Season-1

Kavya's latest attempt at marriage fails when her fiancé's family demands her to transfer her family's ancestral property to her future husband's name, which would leave her widow mother and unwed younger sisters homeless. Kavya later falls in love with her friend and tenant Sreejith, only learning after they are engaged that he loves her sister Keerthi.

Keerthi begins working for Siddharth, and after a time they confess their love for each other. However, his best friend Jeeva expects Siddharth to marry Shivani, Jeeva's sister. Shivani presumes that it is Kavya that Siddharth loves, and so in a misguided attempt to come between them, Jeeva marries Kavya. Kavya later learns of this and accepts her presumed role to protect Keerthi. Marriage plans are finalized for Siddharth and Shivani, but he abandons her to secretly date Keerthi.

Jeeva and Kavya become closer. Jeeva's ex-girlfriend Neethu tries to get Jeeva back by claiming that he is the father of her unborn child, faking a DNA test. She, Shivani, and Dhyan (the biological father of Neethu's child) then attempt to kill Jeeva. This fails, and Vijaylakshmi, Jeeva's grandmother gives ownership of Ishwaramatam Group to Kavya. Later, Jeeva and Vijaylakshmi work together to expose Neethu and Dhyan, who are thrown out of Ishwaramatam.

Shivani and her mother, Indira Bhai plot to have Neethu suffer a miscarriage, and they blame it on Kavya. Neethu presses charges against Kavya, but Jeeva sets himself up as the culprit to save Kavya, jeopardizing his film career. Kavya and Sreejith save Jeeva and Indira is arrested.

Shivani steals money which was meant for Jeeva's new film project, and uses it to release Indira from prison. Conflict results as blame shifts over the lost funds. Keerthi resigns from the company along with Siddhu, whom she pressures into marriage. With Indira's help, Shivani plots against her brother Shiva, having him kidnapped but saying that Kavya and Jeeva won't pay the ransom to turn Shiva against them.

Indira blocks the sale of a property needed to finance Jeeva's new film project, leading to her expulsion and a lawsuit. Kavya is pressured to appear in the film. Shivani destroys evidence and frames Siddhu, causing a rift between Kavya and Keerthi. Pregnant Kavya is hospitalized when Shivani poisons her food. The machinations eventually become too much for Shiva, who admits to his misdeeds with his mother in order to protect Sreejith's sister, Sreekutty's baby.

Jeeva suffers amnesia following an auto collision, with the family warned not to force his memories. He misbehaves and quarrels with Kavya, who is explained to be his nurse, but when she leaves he has her brought back as his secretary. Although Shivani schemes against Kavya, Jeeva realizes his feelings and arranges to propose to Kavya. Kavya learns of this and gently tries to explain their life together but Jeeva develops a severe headache and cannot understand.

Jeeva is arrested for abducting Abhirami, said to be his wife, who is found in a mental asylum. She and the police convince Jeeva to take responsibility and bring her home, and he tries to make amends though others in the family say she is a fake. Abhirami schemes to have Kavya expelled from the house. Jeeva reads Kavya's diary and realizes that she is his wife and carrying his child; uncertain of who his enemies are, he feigns ignorance of this but is more caring toward Kavya. After Abhirami's claims become more outrageous, Jeeva confides to Kavya that he remembers her, and asks her help catch those responsible for his automobile collision.

Later another girl, Sahira, is appointed to take care of Kavya's health. Kavya, however, miscarries the baby and requests Sahira to be a surrogate mother of Kavya and Jeeva's child. In return, Kavya takes care of the expenses of Sahira's sister's treatment. Sahira accepts the proposal. However things took a turn when another man, Shankar, claims that Kavya is his wife and shows photographs to Sahira. He raises the claim in court. However Kavya proves him wrong in Court. Things go downhill when Sahira miscarries the child. Later Kavya finds that she is again pregnant with Jeeva's child.

A marriage proposal comes Shivani's way. The guy, Jayesh, is a doctor. Indira wants Shivani to marry Jayesh thinking about the status they could get once Shivani is married to a doctor. The astrologer, however, tells Vijaylakshmi and others, that if this marriage is solemnised, it could create problems in the groom's family. Later Kavya and Jeeva plans to trick Indira. They make Shivani and Indira observe several poojas. The marriage finally took place and the situation quickly deteriorates.

Neethu and Dhyan tries to ruin the marriage by telling Jayesh about the relationship Shivani once had with Sidharth. Shivani seeks help from Kavya and Kavya discloses the truth to Jayesh. He, however, states that he is not bothered by such stories and fires Dhyan.

Listening to her mother's advice, Shivani creates havoc in Jayesh's house. Jayesh slaps Shivani when she questions about the purity of his mother, Vanaja, who is a retired school teacher. Indira challenges him claiming that she will make him pay for slapping her daughter, Shivani. A case is filed and Kavya appears for Jayesh and his mother and pleads not guilty. They win the case and Shivani and her mother feel disappointed. Later Shivani finds that she is pregnant with Jayesh's baby. Indira, however, forces her to abort the baby. Dr. Annie Thomas who is an old friend of Dr. Jayesh, informs him about Shivani's pregnancy. He requests her to somehow convince Shivani and Indira not to abort the baby. In an attempt to cause abortion, Indira mixes poison in the pudding made by Vijaylakshmi. Shivani is suspicious and seeks help from Jeeva and Kavya. Also Shivani finds Jayesh with a new girl. She is disturbed and follows Jayesh. Kavya and Jeeva later decide to take Shivani back to Ishwaramatam with them. It turns out that the girl Shivani saw with Jayesh was his cousin, Devika.
