[5] 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.

Marriage plans are finalized for Siddharth and Shivani, but he abandons her to secretly date Keerthi.

She, Shivani, and Dhyan (the biological father of Neethu's child) then attempt to kill Jeeva.

Shivani and her mother, Indira Bhai plot to have Neethu suffer a miscarriage, and they blame it on Kavya.

Shivani steals money which was meant for Jeeva's new film project, and uses it to release Indira from prison.

Indira blocks the sale of a property needed to finance Jeeva's new film project, leading to her expulsion and a lawsuit.

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.

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.

However things took a turn when another man, Shankar, claims that Kavya is his wife and shows photographs to Sahira.

The astrologer, however, tells Vijaylakshmi and others, that if this marriage is solemnised, it could create problems in the groom's family.
