Karthik waits until Poorni and Raghu's marriage is confirmed before telling Shakti. She and her husband have not spoken to each other for a long time. This development takes place without Shakti knowing. He arranges a blind date between the two, which initially fails, backfiring on Karthik, however, with more meetings, Poorni and Raghu become closer. Meanwhile, Karthik takes it upon himself to sort out Poorni's adjourned marriage proposal to Raghu.

Wracked with guilt, the two return home, their relationship taking a turn for the worse. Upon arrival they get the news that her father has died. She and Karthik decide it would be best to visit him. Shakti learns that her father is seriously ill back home. They cope for a while, however it's not too long before the couple start arguing over various issues that the two seemed so much more tolerant of before they got married. With the help of friends, Shakti and Karthik move into an apartment, in development. Karthik and Shakthi are thrown out of their homes. Shakti eventually tells the truth, and Poorni's engagement is called off. Shakti's mother Saroja urges her to accept the marriage proposal, unaware of the fact that Karthik and Shakti are already together. The prospective groom's father offers his second son's hand in marriage to Shakti. Poorni is willing to marry the suitor - Raghu. Poorni gets a engagement proposal soon after. With the help of their friends, and Shakti's older sister Poorni (Swarnamalya), they marry legally, and they continue to meet without their parents' knowledge. They decide to get married, without telling anyone, but carry on living with their parents, hoping that a time will come when both families will see eye to eye and can be told of the development. Unable to stay separated for very long, coupled with chance meetings, Karthik and Shakti find themselves resuming their relationship, albeit secretly, without the knowledge of their respective families. Shakti decides not get married without her parents' consent, and the relationship is called off altogether.

However, upon meeting, the two parents disagree and the wedding is called off. He asks Selvaraj, a railways employee, for his consent to a marriage between the two young lovers. Karthik's father Varadarajan, a lawyer, learns of the relationship and meets with Shakti's dad Selvaraj. Karthik and Shakti eventually fall in love. The two meet regularly after their that on suburban trains, to and from work and university. Karthik (Madhavan) is an engineering graduate who happens to lay eyes on Shakti (Shalini), a medical student, at a wedding.
