Vasanth joins a Chennai engineering college and immediately clashes with Shankar, a hot-headed senior. Their initial hostility is sharpened by small clashes and pride, setting up a tense dynamic that will shape their future. The campus atmosphere is charged with rivalry as the two test each other's limits.

During a tense encounter with street ruffians, Vasanth steps in to defend Shankar. Impressed by Vasanth's humility and restraint, Shankar's respect grows and the two begin to see each other as friends rather than rivals. The act proves Vasanth's calming influence over Shankar.

Vasanth is invited to Shankar's house, but overhears Shankar's mother questioning why he would invite guests. The cold reception unsettles him, prompting an excuse to retreat and leaving Shankar embarrassed. The moment foreshadows deeper family tensions.

Despite the rocky start, Shankar's mother gradually understands Vasanth's good nature and grows affectionate toward him. This change strengthens the fragile trust between Vasanth and Shankar’s family. It also deepens the contrast with Shankar's protective, secretive past.

In a separate thread, Vasanth chances upon a girl at the Coimbatore railway station and is drawn to her. He pursues her with persistence, and the situation leads to a misunderstanding with the police that lands him in jail for eve-teasing. The girl turns out to be Priya, Shankar's younger sister.

Vasanth is jailed after a rumor-laden incident. After his release, he chooses not to reveal Priya's identity or his involvement to Shankar or his mother, and withdraws from her life. Priya, however, learns that she loves him in return.

Vasanth and Priya's affection survives in private as they struggle to navigate the obstructive loyalties to Shankar. They refrain from making their romance public, fearing how their families will react. The tension builds as Priya's feelings grow stronger.

Before any public confession, Shankar discloses to Vasanth that one of his closest friends betrayed his family. The revelation forces a shift in their relationship and prompts a flashback to the past. It illuminates the fragility of trust within their circle.

The story rewinds to Shankar's family history, introducing Shanthi, Shankar's sister, and Shakthi, his close friend. Shanthi runs off to marry Shakthi, triggering humiliation and betrayal from the wedding party and police as Shankar and his mother try to salvage the family. They eventually disown Shanthi.

Seeing echoes of his own dilemma in Shankar's past, Vasanth resolves that love should not override friendship. The moment hardens his resolve to stay loyal to Shankar and his family even as his feelings for Priya grow. It marks a turning point in his moral code and future decisions.

As Priya's family presses to arrange her marriage, she despondently consumes poison in a desperate bid to win time and secure a chance with Vasanth. She is rushed to the hospital, highlighting the danger of their unspoken love. The incident intensifies the sense of urgency for a resolution.

Boopalan reveals to Shankar and the family the true depth of Vasanth and Priya's love and how Vasanth sacrificed his own happiness for his friend's sake. Moved by the loyalty, Shankar declares his pride in their friendship and gives his blessing for the couple's marriage. This moment seals the alliance between the two families and the couple's future.
