September 1988. One evening, five neighborhood friends, all born in 1971, watch "A Better Tomorrow II" in the bedroom of Taek, when their parents call them down for dinner.

Deok-sun is the middle child of the Sung family, led by Dong-il and Il-hwa, that struggles to make ends meet. She fights a lot with her older sister, Bo-ra, who is a top university student, and is sometimes jealous of her younger brother, No-eul. Deok-sun demands her birthday celebration to be separated from her sister's, whose birthday is a week before hers. They live in a 'half-basement' home. Jung-hwan is the youngest child of the Kim family, a family of relative wealth, which lives upstairs to Deok-sun. Their breadwinner is Sung-kyun, an eccentric and often childish electronics store worker. The father's behavior is frowned upon by Jung-hwan and his mother, Mi-ran, and by nearly everybody except Deok-sun. The tech-savvy first-born son, the 24-year-old Jung-bong, refuses to study and angers Mi-ran further. Sun-woo is the oldest child of his family and lives with his widowed mother, Sun-young, and toddler sister, Jin-joo, in the block next to Deok-sun's. His mother is a bad cook, but he approves of her cooking because it's hers. Across the street, Dong-ryong lives with two full-time working parents, Ssangmun High School's fearsome dean, Mr. Ryu, being his father. The families share and switch side dishes to go with their evening rice, sending their children to exchange those dishes. Taek, who lives next to Dong-ryong, goes downstairs and has dinner with his widowed father, Moo-sung; their dinner table is slowly filled with dishes their neighbors brought to them.

The neighborhood mothers discuss whether sons or daughters are best while preparing food. Dong-ryong and Jung-hwan confront a gang of people who want to steal their money to buy tteokbokki and lose their sneakers, after their classmate 'Michol' (nick-named after a Dooly the Little Dinosaur character)^[12] has lost all of his money. Sun-woo involves himself in the case and hurts himself in a fight, and his mother is concerned about him, especially after finding his room empty after calling him for errands. She is concerned that her son had taken up smoking, but he comes home after buying a drink for his father's altar.

Deok-sun is preparing hard for her role as picket holder for the Madagascar delegation at the Seoul Olympics opening ceremony, about to be held on her 18th (Korean age) birthday. She struggles, but she is committed, practicing every night in the bedroom she shares with Bo-ra and in the streets after rehearsing. As she is one of only three high schoolers taking part in the event, the entire neighborhood is talking about her role. Stakes become very high when rehearsals start in the Olympic stadium. During a TV interview, Deok-sun finds out that Madagascar is part of the countries that refuse to take part in the games. However, her reaction in the television broadcast impresses the Olympic organisation, and she is reassigned to the Ugandan delegation. After fulfilling her role as a picket holder in front of the world, she comes home to her father, who gives her a separate birthday cake.

Grandma, the mother of Dong-il, visits the Sung family. She tells her granddaughters about how she bore and raised two daughters and two sons, and how the oldest-born son worked jobs to earn money at a young age so that their father could study hard and become a banker. Deok-sun adores her.

The next morning, Deok-sun is late for school, but finds time to greet Taek on her way. Deok-sun is befriended with two classmates at the Ssangmun Girls' High, Wang Ja-hyun 'Joey Wong' and Jang Mi-ok 'Maggie Cheung'.

The parents joke about how everyone wants Taek, a Baduk player of the 6th dan, to be their son-in-law after he wins a major tournament with the equivalent of 50.000 dollars in prize money, enough to buy a high-end apartment. Bo-ra later comes home, and announces that her superior wants her to go on a trip.

The Seoul Olympics have come to an end, with Korea winning the largest amount of medals in their history. Dong-ryong, who has instant foods for his meals every day, complains how bad Sun-woo's meal is, to the disdain of the class president. The boys later play shirtless soccer, and Sun-woo impresses the opponent's captain. He is picked on for wearing his father's bracelet by the opponent, but defends himself. That evening, Dong-ryong plans to sneak into the cinema without tickets, but rethinks that and instead borrows an adult movie to watch at Taek's. The next evening, Dong-ryong, Sun-woo and Jung-hwan attempt to hitch a seat at the cinema, but they get caught.

At the girls' school, the juniors each get a different book about romance or another topic to read. Deok-sun panics when she hears she has to meet the headmaster. Instead of a punishment, she gets a phone call with bad news: her beloved grandma has died.

When arriving at grandma's hometown with her family, she is surprised that nobody, including her dad, feels down or saddened, happily eating Korean barbecue and drinking copious amounts of soju. Dong-il is instead happy to see family and friends again who he has not seen for a long time. Only after the first-born of grandma, coming all the way from a laundromat in the United States, arrives at the site, everyone breaks down.

The next evening, Dong-il is back in town, and asks Taek when he misses his mother the most. Taek, who lost his mother at the age of five, responds with a clear answer: every day. As the youths come together to celebrate his birthday, the episode flashes back to the 1970s, when they were toddlers. Taek moved to Seoul with his father after his mother died to cope with the loss, and despite his shyness, he was accepted as a friend by the other, much noisier kids.

October 1988. Joey and Maggie congratulate Deok-sun with getting a boyfriend after assuming Sun-woo has a crush on her. She has in fact dated Sun-woo for the first time in the past summer. The girls practice hard for their performance at a school trip, with a cassette player at stake. Deok-sun is motivated, because she now has to share her player with her sister.

Dong-il gets mad after seeing boiled potatoes on the dinner table. Il-hwa is mad at him for spending all the little money that is left after paying expenses and debt on useless things and alcohol, instead of saving it. Dong-il then proceeds to say that sellers of useless things are sympathetic, as young as his children or reminiscent of his mother. Mi-ran is irritated with Sung-kyun to such an extent that she jokes about selling him off. Jung-bong is caught saving postal stamps instead of studying. Il-hwa tells Mi-ran that the Sung family is poor, because they are indebted. Moo-sung struggles with cooking meals for his son.

When she goes off with her school on the trip, Deok-sun is reminded to never lose her parents' expensive camera. When she finds out that she left the camera in the train, she breaks down, and her headmaster informs her parents calmly about this event. She continues the trip with a good mood. Meanwhile, No-eul is caught selling alcohol in the streets, and Il-hwa is concerned further. Sung-kyun buys an expensive jacket which he thinks is of good quality, only for his wife to easily break its zipper.

When Joey and Maggie attempt to venture into the boy's pavilion, they are injured after falling from a high ledge. Jung-hwan, Dong-ryong and Sun-woo are reluctant to replace them, but they accept the offer. They perform so well that they win the cassette player for their neighborhood friend. Deok-sun and Jung-hwan run off, but are being chased by master Ryu. They are driven into a small hole in the wall, where their bodies are pressed against each other. Deok-sun gets home, and is chased by an angry mother because of losing the camera.

November 1988. Deok-sun and Jung-hwan miss the bus to school. The next day, they succeed, but it gets tumultuous in the full bus. In an attempt to stabilize herself, Deok-sun rips open the shirt of Jung-hwan in an embarrassing moment. As their final year of high school gets closer, the youths of Ssangmun spend more and more time in rooms dedicated to studying. They listen to music, study and fall asleep. Deok-sun has decided to study hard, but refuses to get tutored by Bo-ra.

The parents eat with the Kim family, where fried fish is served; a luxury for the Sung family. In order to get better at focusing, taking up Baduk is suggested for Deok-sun. She spends one evening with Taek, where she fails to remember the rules of Baduk.

It's Mi-ran's birthday, and the Kim family eat out at a pork cutlet restaurant. When Sung-kyun calls everyone for dinner, the family members appear distant to each other, and the family elder struggles to keep everyone together and in a good mood, while the waiter asks if he could take a picture of them as a souvenir. Dong-il is revealed to like marinated clams so much, he angers his wife over their absence at the dinner table. Tired of the fights between his parents, No-eul puts on the TV loud. After coming home, Sung-kyun tries to attract family members by buying premium ice cream, but finds the box untouched and the ice cream melted. Drinking in broad daylight, the ladies complain about their husbands' behavior, and deem Sun-young the luckiest one before suggesting she should be together with Moo-sung. The kids gather to get tutored by Bo-ra. She is gravely disappointed with the work attitude of most of her juniors.

Taek lost to a novice opponent, and has difficulties dealing with his very first professional match loss. The neighborhood friends come to help, skipping dinner with their parents to gather at his place. They say discouraging things to Taek, who soon realises they are jokes. They teach him to let things out by swearing, and they spend the rest of the night doing fun things.

Disappointed with the school grades of their middle child, Dong-il and Il-hwa eat at a restaurant together to cope. They see another couple loving each other, and that inspires them to get along. Sung-kyun gets further disengaged with the rest of his family. Jung-hwan realizes that, and greets his father the way the elder likes to greet Deok-sun, only to tell him he eats dinner elsewhere. His mood is lifted when his wife makes him a hot meal and asks him for soju. Similarly, Il-hwa cheers Dong-il up with freshly marinated clams.

After former President and dictator Chun Doo-hwan apologizes for his actions, Seoul experiences a wave of renewed student protests. Dong-il is caught in these protests and gives his pocket money to a student to pay for his way home. The breadwinner gets home safely, but with Bo-ra nowhere in sight. Bo-ra later enters the living room and fights with her parents. In her room, she cleans up wounds on her forearms and checks a note for a follow-up meeting with a political party. When the mothers gather, Il-hwa assumes that her eldest daughter is taking part in the protests.

During recess, Sun-woo successfully re-enacts a popular commercial, but when asked to do it again, he falls and injures his ankle. Concerned about her son, Sun-young plans to cook him certain foods, but Sun-woo thinks she may not be able to afford the ingredients needed. She buys both of her children banana milk instead.

When an amount of briquettes are delivered to the Kim household that could warm their house for a thousand days, Sun-young defends herself against comments about her poverty and appearance. Mi-ran, who had to warm her house with firewood until not long ago, is concerned about the way Sun-young's mother-in-law treats her daughter-in-law. When Sun-woo's paternal grandmother pays a visit, Sun-woo politely declines any conversation, after which she talks down on Sun-young on her financial situation and how she lives in her house for free, on the pension of her son, after he died.

Deok-sun goes to the study room for the first time, but soon falls asleep. She dreams of being in a relationship with Sun-woo. At the meantime, Jung-hwan is asleep in front of the TV and dreams of being in a relationship with Deok-sun. Leaving the study room late, she manages to get a ride home under Jung-hwan's umbrella.

Mi-ran is irritated that the men in her house are lazy, dirty and incompetent in doing housework, or at least appear as so. A concerned housewife, she explains everything that needs to be done in the house in detail before she leaves home for the weekend to tend to her mother, who has injured herself. Jung-bong turns out to have extensive expertise in housekeeping. After Mi-ran leaves, the gentlemen do as they wish, finish the leftovers she ordered them to eat for dinner and clean the house in a hurry just before she returns. It turns out that they intentionally keep Mi-ran busy with tasks since she could afford to be a housewife.

Deok-sun is requested by her parents to study as hard as her older sister, when the latter is seen protesting in front on television. Bo-ra comes home, and her parents are enraged. She is grounded by her father, who guards the door of her room tightly to prevent her escape in the middle of the night. Her mother insists that she at least gets to eat.

Unlike her mother-in-law, Sun-young's own mother is a warmhearted person who cares about her children. She pays a visit to her, shows concern for Sun-woo, and brings in goods before having to leave quickly. Luckily, she has time to call her daughter by phone that evening. Jin-joo requests a banana from her mother, which costs a fortune in 1980s Korea. After receiving a hefty sum of money from her mother, Sun-young treats her children with a real banana.

One day, Il-hwa finds her daughters' bedroom empty and searches for her troubled daughter. Bo-ra is on her way to a conference with the protest group when she gets arrested. Only after her mother defends her firstborn child to the tooth by explaining that her child is the pride of the neighborhood, Bo-ra confesses to the police officer and her mother what she has done.

December 1988. Dong-ryong helps pack Taek's suitcase for his next tournament in China and requests him to buy pizza for his friends when he gets home. Taek instead insists that he watches a movie with his prize money. At the tournament, he is the only representative of Korea left, and he has a handicap of three dan against most opponents and six consecutive lost matches behind him.

Jung-bong regularly writes letters to the editors of the nationally broadcast radio program Starry Nights, and with his seventh college entrance exam upcoming, he gets several letters of his read on the show, in which he wishes good luck to Taek and praises Bo-ra. Taek makes it to the final round of the tournament, and Bo-ra saves his butt while he is confronted by two unruly, smoking men.

Jung-hwan finds out that Deok-sun plans to send a letter about her crush on Sun-woo to Starry Nights. Taek wins the tournament, and orders pizza to eat for his friends. During the pizza party, Jung-hwan asks Sun-woo to confess his love on the first day of snow. Instead of confessing to Deok-sun, he meets up with Bo-ra on the first day of snow. When she bawls her eyes out after realizing that Sun-woo has his eyes on her sister instead of her, the love letter she sent to Starry Nights is read aloud on the show.

The neighborhood's children play Secret Santa on the initiative of Jung-bong, who is collecting LPs and would like someone to buy a record he misses from his collection. Bo-ra does not like taking part in games, but Sun-woo insists that she still take part. Dong-ryong meets the fate of picking his own name.

The parents discuss which presents to get for Christmas. For long hours, they cannot decide how to play Santa for Jin-joo, who is purposely kept asleep. Sun-young tells the other parents that Jin-joo was told the previous year (by Bo-ra) that Santa does not exist, which the toddler later confirms. Nevertheless, the parents try to make her believe in Santa again, as only he can get what she wants: a snowman.

Sun-woo meets up with Jung-hwan, who insists to watch Die Hard with him later that afternoon. He declines, as he finds more value in studying. Jung-hwan then tells him that he found out about his relationship with Bo-ra, and is surprised that he does not like Deok-sun.

After the parents have decided what to get for Jin-joo, they all insist to leave, but Sun-young and Sung-kyun decide to order Chinese. Moo-sung is concerned that Taek won't eat dinner while he is training at the Baduk association, doing everything he can to bounce back from several consecutive losses. Il-hwa asks Deok-sun to order delivery for the entire block, while Sung-kyun and Mi-ran are fighting. Moo-sung waits outside the association, in streaming rain, for Taek to come.

During dinner, Dong-ryong is revealed to also know about the relationship between Sun-woo and Bo-ra. Jung-bong and No-eul are shown to be good friends. Jung-hwan sneaks into Deok-sun's bedroom to read an adult content book. Deok-sun comes in and is embarrassed about this. They exchange rumors about which person has drawn which person's name. It is revealed that Deok-sun has to buy a present for Jung-hwan. Moo-sung sits down for an interview about his son shortly before he leaves to Busan to compete.

Taek calls Deok-sun and asks what he could get for his father as a birthday gift. Deok-sun misinterprets this, thinking that he has picked her for Secret Santa, and asks for pink gloves. Mi-ran gets jealous of Sun-young because of the good-hearted, hardworking nature of Sun-woo compared to her own two sons. Instead of forcing Dong-ryong to sleep at home, Sun-woo puts him in a more comfortable position in the study room, as he understands that he does not want to sleep where his dad is. He then goes outside to meet Bo-ra. It rains, and Sun-woo does not want her to get wet, so he gives her his umbrella, much to her dismay.

Sun-young meets with Moo-sung after the interview. The interviewer had asked for his wife's conception dream and time of his son's birth, something fathers cannot answer. Moo-sung feels sorry for his son for not having an ordinary childhood and ordinary household, especially when it comes to food. Sun-young then tells him she saw him trying his very best to be a good father to his son, and Taek really appreciates that. Moo-sung then spends much of his time drinking. Taek goes home and brings his father a present: pink gloves. Moo-sung is very appreciative of this gesture.

Deok-sun meets with Joey and Maggie at a McDonald's, far away from Ssangmun, where they ask Deok-sun if a boy she knows could join the table, preferably Jung-hwan. Deok-sun is disgusted, but still calls Jung-hwan, which arrives at their table surrounded by a flattered Joey and Maggie. Deok-sun goes home with him that night, and he tells her that he has Taek as Secret Santa, to the unpleasant surprise of Deok-sun. On Christmas Eve, the teens watch the MBC College Campus Song Festival together (the series' title song wins it that year).

The parents discuss how exactly they would build the snowman they had promised Jin-joo, because upcoming rainy weather would make that very difficult. They come up with the idea to sculpt a snowman out of ice, since there is an ice vendor in the neighborhood, and they are not worried about rain on Christmas Eve. The sculpture is a success, however, it melts entirely, as it does rain on Christmas Eve. Sun-woo clarifies to the disappointed parents that Jin-joo referred to a waffle cone with two scoops of vanilla ice cream, and gets some for his sister at the nearby shop.

Every morning, Moo-sung makes breakfast for his son and sweeps the street, this time showing off his pink gloves.

Deok-sun meets with friends at the tteokbokki shop. Joey and Maggie think that Deok-sun has a crush on Jung-hwan, angering her. When Deok-sun returns home, she finds her mother angered, because a large sum of money disappeared out of her wallet. Bo-ra immediately suspects her younger sister, while Deok-sun thinks No-eul did it. Il-hwa suspects that her son is in the rebellious phase of his life and does not blame him. Dong-il comes home late. Drunk, he is yelled at by his wife for using up his time and money to 'help out others'.

Jung-bong fails his college admission exam for the sixth time. Mi-ran is mad and disappointed, while Sung-kyun says failure is nothing to worry about and is still proud of his oldest son. The parents worry about his upcoming heart surgery: Jung-bong wears a pacemaker and needs to have its batteries replaced. The once-poor family can now afford the best hospital of the country to perform surgery on Jung-bong. The oldest son is still very scared and concerned that he would not make it, packing all his possessions in boxes in case for the worst.

Bo-ra and Sun-woo call each other. Sun-woo suspects that Bo-ra already has a boyfriend. The boys discuss how people show that they are attracted to someone. Bo-ra meets up with a good college friend, who reveals that she has kissed Bo-ra's boyfriend. Bo-ra sees her boyfriend and he tells her that he ends his relationship with her. Sun-woo remarks that it was Bo-ra that advised him to express his feelings when his father died two years ago, and formally begins his relationship with her.

For the surgery, Jung-bong needs to be sober and not consume any food for an extended period of time. Mi-ran brings festive foods to the hospital, which her son refuses to eat. Sung-kyun praises the strength of his wife. The night before the surgery, Mi-ran tells Jung-bong that he is very strong, having to deal with a heart condition since a young age, and breaks down in tears. The surgery is a success, and Jung-bong does not have to go under the knife for a decade.

January 1989. Dong-il and Il-hwa warn their youngest children about kidnappers and low grades. Deok-sun is almost attacked by a kidnapper, who turns out to be Jung-hwan. The parents notice that Moo-sung is absent and his shop closed.

Starry Night organises a public jam session on January 11, with big names on the lineup. Deok-sun is particularly excited about this concert. She reluctantly attends the jam with Jung-hwan after the other boys reveal that they have other plans; the two get a picture taken at the concert together. Sun-woo continues dating Bo-ra, but struggles in connecting to her as a loving person, instead of Deok-sun's childhood friend. Bo-ra masks her dates, saying she meets up with fellow student protesters. The relationship fares well, despite the fact that Bo-ra is older than Sun-woo.

Life continues to be unfair for the widowed parents. Moo-sung is in Busan to pay respects to a friend of his who recently died at age 45, leaving behind a wife and 10-year-old daughter. He explains the harsh reality of life and death to another friend, who is grappling with grief and uncertainty. Taek stays home and eats with his neighbors. Sun-young receives a letter from the district court that her house, formally owned by her mother-in-law, would be taken from her and sold if she does not complete a payment of 10 million won. She is afraid of taking too much money and help from her fellow housewives to make ends meet. Shortly after Moo-sung returns home, he falls unconscious and collapses. Dong-il, who planned to have some drinks with him, arrives on time to call emergency services and save his life. This incident means that someone else than his usual companions must accompany Taek during his upcoming tournament in Shanghai. Moo-sung appoints Deok-sun for that task, assuming she likes his son.

Deok-sun receives a coveted passport and travels to China to assist Taek with his tasks. In the hotel, she becomes known as a chaotic, but cheerful and lovable young woman, who communicates the best she can with the Chinese staff to get everything according to her and Taek's wishes. Taek sleeps well without the abundance of sleeping pills he usually takes, and plays Baduk at his best. Deok-sun gets a picture taken with Taek at the hotel after the tournament.

Deok-sun meets with Joey and Maggie, who consider going to a group date, at her house. They tell her that Jung-hwan appears to actually have a crush on her, judging on his remarks. Sung-kyun has bought a new car, much to the dismay of his wife. Jung-bong is crazy about Bubble Bobble and attempts to finish all of the game's levels on one coin, gathering angry elementary schoolers around him. Instead of playing at an arcade elsewhere, he persists, and as he runs away from the young boys mad at him for not letting them play, he crashes into Maggie and instantly falls in love with her.

Sun-young takes care of Moo-sung until he recovers and prepares him meals. She is concerned about him when he plans to help clear the table and do other tasks. Bo-ra is busy studying and leaves the ticket for a concert she planned to attend with Sun-woo on the desk of her study room. She rushes to the concert hall to bring the ticket back to him, but ends up attending the concert.

Sun-woo, Bo-ra, Jung-hwan, Deok-sun and Taek head to the beach, where Dong-ryong is also going. Deok-sun accompanies Taek throughout the trip, eating at cafes and playing Baduk against elderly men, who praise him for his skills. Taek and Deok-sun then go for a walk on the cold beach, when a volleyball shoots their direction; Taek protects Deok-sun from the impact.

Sung-kyun celebrates his birthday, but he is not as happy as usual. It is this time of year that he feels melancholic, as he longs to his mother every time he is served seaweed soup. He decides to throw out stuff he had put in boxes and stored somewhere. Mi-ran stumbles upon an old audio cassette from when the boys were still toddlers, and plays it.

Dong-ryong also celebrates his birthday. After being tasked to throw his own party with his parents' money for years, he is eager to finally get seaweed soup from his mother, Chief of an insurance company. As he comes home, he finds out it is the usual situation: his parents do not care about him. His friends throw him a birthday party instead.

Il-hwa, Mi-ran and Sun-young go to a fortune teller. She tells that Jung-bong awaits great fortune in life, causing Mi-ran to think that he will finally make it into a university this year. She estimates that Sun-woo is bound to do well, but Sun-young is destined to be more fortunate than her son. To Il-hwa, she advises her middle daughter to be called by the name Soo-yeon from now on, because it would increase her chances to go to a college in Seoul. At home, Dong-il disagrees with the prophecies of the fortune teller, especially with calling his daughter by another name.

Joey is sad because a boy dumped her. Maggie and Soo-yeon immediately know why: Joey has confessed her love towards him too soon. Jung-hwan asks himself if he could get a hold on Soo-yeon as he realises that Taek is a serious challenger. Mi-ran gathers the neighborhood for a meal of Hamburg steak. Soo-yeon is asked to drop the meal off at Taek's room, as he refuses to leave his room in preparation for his next match. Soo-yeon holds on tightly to her new name, determined to make it into college.

The mothers play Go-Stop. As they discuss playing against Mr. Ryu to the men, they are warned about the dean's cheating behavior. Sun-woo always insists to be the good son and eat dinner with his mother and sister every evening, no matter his schedule. To stretch the ends of her husband's pensions and simply have more to spend, Sun-young now works as a cleaner at a jjimjilbang every evening. She tries her best to not make her children realise. Dong-il, revealed to be an anti-fraud inspector at his bank, plays a match of Go-Stop against Mr. Ryu and soon overpowers the dean by barring him from cheating. The Kim family hears that Jung-bong has failed his college entrance exam again, leading to Mi-ran distrusting the fortune teller.

As Sun-young decides to work longer hours during the holidays, Moo-sung meets up with her more often, and babysits Jin-joo when she is working. As now, all Koreans are allowed to travel abroad, Mi-ran and Sung-kyun prepare to go vacationing in China for Lunar New Year. While Sun-woo and Bo-ra have their first kiss, Jung-hwan and Soo-yeon spend the night together, in one bed.

February 1989. Between long hours of studying, Sun-woo and Bo-ra meet up as often as they can afford to. Aiming to keep their relation secret, they call each other up in the middle of the night one day, but the younger kids in the street notice. Taek notifies to his friends that he can confirm they are in a relationship, angering Soo-yeon. Bo-ra brings food to Sun-woo and they stay in his room until Sun-young comes in, while Soo-yeon joins the dinner table at Jung-hwan's.

Sun-young negotiates prices on the market while Moo-sung improves his relationship with Jin-joo, who is learning how to write. The mothers discuss their children's grades and school attitudes as they approach their last year of school. Jung-bong is in a letter writing frenzy, hoping that he can keep in touch with Maggie. Bo-ra tells Sun-woo she is studying to become an accountant to earn extra money, as teaching math would be difficult because, owing to her participation in the student protests, she now has a criminal record. Dong-ryong loans a tape with 'X-rated content' from Michael; he and Taek get scammed.

As the friends get together to eat cutlets, and Soo-yeon leaves for the toilet, a man with a long coat approaches her and shows his business. She manages to fend the man off by telling him he has a sausage too small to impress anybody, then breaks down in tears. Taek enters the lavatory to comfort her. Sun-woo is favoring Bo-ra over cutlets, and finds out that his mom is cleaning bathrooms all evening.

When walking down the streets with Jung-hwan, Soo-yeon has a shock encounter with her middle school crush. Back home, she is asked by Moo-sung to encourage Taek to eat, as he is facing his next tournament. Dong-il and Sung-kyun drink and play Go together, while Sun-young discusses remarrying. Bo-ra meets up with her friends while planning to meet up with Sun-woo, who is introduced to them as a younger sibling of hers.

Jung-bong sends chain letters to the kids in the neighborhood. The block gets threatened by a thief and chase him down, only to find out it was someone they know. The kids play Blue Marble, and Sung-kyun is busy trying to fix things, angering his wife by making things worse. Concerns about Taek grow when news of a plane crash comes out.

Dong-il and Il-hwa are having a medical checkup, paid for by the husband's employer. The wife is concerned that she has breast cancer. Dong-il and Il-hwa concern themselves so much, they could not gather the energy to make dinner for the household. Fortunately, the doctor finds out Il-hwa just has a pocket of water under her breast.

March 1989. Taek brings home fruit after winning the tournament and shares it with the neighborhood. Bo-ra studies hard, although Sun-woo alerts her about public holidays. The Kim family's clothes iron has broken down, and Sung-kyun manages to fix it, but as a result, the plug cord is too short for Mi-ran to actually iron clothes with it. Sun-woo builds a model plane for a school competition, using the instructions his father gave him when he was younger. He sees no problem with his mother working as his little sister grows up and gets taken care of by Moo-sung, as long as mom takes good care of her health. He later breaks down in tears, thinking about how hard his mother works for him, and he is not used to another man taking care of his mother and sister.

Dong-il comes home late again after binge-drinking at the local stall after work, where he met up with the person to whom he is indebted to. Dong-il comes home, and announces that his debt has been paid off. The next morning, Il-hwa cooks a feast for breakfast, and the children beg for sneakers as they are about to restart school. The parents talk to Bo-ra about how they regret not being able to support her financially back then.

Things are getting serious for the neighborhood kids now that they are in their final year of high school. Dong-ryong still refuses to focus on studying, and a new student takes her seat in the class of Soo-yeon. Maggie tells Soo-yeon and Joey she is going on a date with Jung-bong. They both arrive at the same restaurant, but take a seat on different floors, never meeting each other. After Jung-bong leaves out of frustration, Soo-yeon insists he return to the restaurant, and he succeeds in finding Maggie. The two have their first kiss.

Sun-woo thinks about his father often, and mentions that even though he likes soccer and gladly plays it with his friends who prefer the sport, his real passion is baseball and he has not been able to play catch with someone since his father died. The new student has an epileptic seizure while in class, panicking everyone in the classroom, except Soo-yeon. When recovering, she is ashamed of who she is, but Soo-yeon manages to make her feel comfortable. The mother of the new student trusted Soo-yeon to do the right thing if her daughter, Song-hee, would have a seizure, because the principal found Soo-yeon best suited for that job.
