Shabnam is controlling DD's house, and Roshni is taking care of Nani and Ayesha. She meets a mechanic named Raghu; who is the exact copy of Sid. She finds him only the way to save her mother and to avenge Sidharat's murder from Shabnam. Raghu helps him like Sid and this against the advice of sumati, his "supposed mother" suffering from mental disorders. With this asset, Roshni follows Raghu during his marriage with Shabnam and thinks that he is Sidharat suffering from amnesia. Raghu acts to be in love with Shabnam as Sid, and takes advantage of this personality to reconcile Sam and Yash. Sid's mother puts up an act of being sick and the truth for Sidharat being Raghu is revealed. Roshni supports Sid and they manage to defeat Shabnam. The day after Shabnam and Raghu's failed marriage, which ended with the arrest of the bride, the Patels and Sid are surprised to see coming to their house a backward Rajhistani family who claims that Roshni married their son Kunal; until she reveals Roshni isn't DD's real girl which turns out to be just blackmail on her part, she leads her and Nani to the wand while Kunal does her better to please Roshni by hiding his violent character. Bansi's daughter and also Kunal's aunt, Skakun falls in love with Sid's father and only belatedly realizes Raj's insincere feelings for her.

Shabnam; who claims to be bipolar to avoid jail, returns to the Pathels after saving Roshni from a traffic accident perpetrated by Kunal. She (initially) pretends to be nice, then allies with Bansi to accomplish her revenge against Sid. Later, they drug Roshni, which causes her to lose her memory, telling her that they are her family.

She leaves him and everyone thinks that she died..

2 years later

Roshni and Sid have been separated after the death of DD as Roshni thinks DD died because of Sid. Two years have passed since Roshni's presumed death. Siddharth still blames himself for being responsible for the incident and refuses to remarry. On the other hand, Roshni, who turns out to be alive, has forged a whole new identity for herself alongside a good friend, Neil. She calls herself Ragini Desai and acts exactly like DD at the start of the show.

When Sid goes to meet Ragini on business unaware that she is actually Roshni, he crosses paths with and saves a girl called Anya from suicide. It turns out that she is part of the Sengupta family, being herself Neil's sister and Ragini's assistant. Her concern is about her illegitimate pregnancy and the abandonment of her fiancé for whom she had to rebel against his family. In order to convince her not to commit suicide, Siddharth proposes to pretend to be her fiancé and to become the father of her child while waiting to find the person concerned.

As the future son-in-law of the Sengupta family, Siddharth regularly visits Anya, without meeting Ragini/Roshni. Some days later, on Roshni's birthday, Sid and Roshni meet again. Constantly, Roshni seeks to get away from Sid to avoid further trouble while Sid himself is blinded by his love for her. When the link between Sid and Anya becomes known to Roshni, she takes it so badly that in revenge, she asks Neil in marriage, who accepts. According to her, it is only like this that they will manage to forget each other.

So, Roshni is going to marry Neil Sengupta. Misunderstandings soon arise considering Roshni always thinks it would be better for everyone if she and Sid don't meet again, which ends up happening in a twist of fate. These characters, once lovers, both become brothers-in-law. But Neil's conspiracies and his bipolarity issue bring them together again, as Anya takes Siddhart's services for love and seeks for a while to separate her alleged fiancé from her sister-in-law.

Meanwhile, the aunt and the cousin of the Segunta siblings are far from stupid. From the start, they never approved of Neil and Roshni's relationship, for the simple reason that they are secretly working on behalf of Neil's ex-sister-in-law, Payal Walia, who has promised to give them more attention than their family if they were to make her the owner of the premises. This goal being finally achieved with the help of Anya, Roshini and Sid reunite to save this family in distress, and reconcile at the same time. Payal is out against Neil's family and creates a lot of drama in their lives.

Later, as Payal is sent away and released from prison and Neil reconciles with Ria, his lost love, Roshni gives birth to a son who is named Karanveer by Neil. Getting ready to join the Khurranas in London, Sid and Roshni are invited one last time by the Sengupta family where they share a romantic dance. Payal, who planned to take revenge, refrains from learning this sudden departure and now being a changed person. Unfortunately, unable to prevent her revenge which she herself carried out, she just hopes to see them leave as soon as possible.

This is how after moving farewells, Sid, Roshni, Karanveer and her governess, Gangu, experience a road accident perpetrated by an old enemy of the Patel family, Gafur, whom Payal allied with in prison. Everyone predicts that Karanveer Khurana has died with his parents, but the truth was that Satya, the son of Roshni's governess, died, but Gangu makes Karan as Satya. Ria gives birth to a daughter who was named Mahi by Sid on the day he died with Roshni. Ria dies after Mahi's birth.

21 years later

Things have changed after the death of Sid and Roshni. Karanveer "Karan" Khurana, Sid and Roshni's son, has grown up. Gangu named him Satya as her deceased son (that's what she believed), raised him and taught him good values despite his innate street boy character. Neil and Ria are dead too. Their child, Mahi Sengupta is taken care of by Payal who changed her surname from Walia to Sengupta. Mahi and Karan's relationship is like Roshni and Sid. But unlike DD Patel who loved her daughter, Payal hates Mahi for her parents' mistakes. By making her brother-in-law her husband, she thought of taking back the property that the Sengupta stole from her. Then finally, she adapted to passing herself off as a nice mother in the eyes of her niece, because this one turns out to be the true heiress.

When Satya comes into Mahi's life, it is Mahi's half-sister, Koyal, who interests him. But Sid's prediction about his son's future had an effect. Satya has fallen in love with Mahi, but Mahi does not immediately realize her feelings for him. Knowing Payal's malicious intentions towards his daughter-in-law, Satya vowed to protect her.

With the help of a friend who will turn against him, he will succeed in bringing down Payal's mask. But she comes back into their lives, still pretending to be a good person. It later turns out that she is in contact with Kritika and is blackmailing her to see her nephew again. Thus, after a series of attempts to repossess Sengupta property that will lead to the revelation of Satya's real identity, Payal is still exposed and goes back to prison while Kritika brings Mahi and Karanveer (Satya) back to the Khurannas.

Along the way, they meet and take in a weirdo who turns out to be an exact copy of an old family acquaintance. It is in fact Kareena, Shabnam's daughter. She also comes back to take revenge for her mother knowing that she took her model just like Karanveer took her father's.

Several attempts by Kareena would later involve the return of a more loving Payal. When Mahi is expecting twins, everyone will be happy. Payal, who has made herself accepted in the family, tries to keep Kareena away from Mahi. At the end of the show, Kareena will be hit by a car after yet another attempt while Mahi, Satya and the entire Khuranna family welcome the newborns to the maternity ward.
