In a climax displaying her disorder, she kidnaps Suji, and Vallavan arrives and frees her. Swapna realizes her mistake and they reconcile, infuriating Geetha. In an effort to win his love, Vallavan once again as Pallan, goes to convince Swapna, and tells her that even though he is younger than her, his love for her is true and that age does not matter.

Geetha returns for payback and tells Vallavan that she is the reason for the current mess in his life. She is not ready to let him go so easily and he teaches her a lesson. Learning of her true nature, he ends things with her. When he was in higher secondary school, Vallavan met the hysteric and toxic Geetha ( Reema Sen), who ensures that Vallavan is mad about her. As Vallavan walks in the streets wondering how things got so messy, he recalls his school life. Meanwhile, a sequence of events take place, much to the chagrin of Vallavan, who is highly insulted by them. When Swapna comes to know that Pallan is younger than her (from one of Vallavan's rivals in the college) and also a student, she dumps him and decides to marry another man. Pallan makes Swapna fall in love with him for his heart. He decides to woo her by turning into Pallan, an ugly duckling with buck teeth and thick glasses. Vallavan encounters Swapna again in college and she is revealed to be a teacher who is three years elder than him. While they are at temple, Vallavan sees Swapna ( Nayanthara) and immediately falls in love with her. Vallavan ( Silambarasan) is a happy-go-lucky college student who is friends with Suji ( Sandhya), Soori ( Santhanam) and Subbu ( Sathyan).
