Shanmugamani arrives at his alma mater as a Tamil teacher. He is a state topper who has risen above poverty, which earns him respect and high expectations at the school. His return starts a tense dynamic with the current twelfth standard batch, especially Priya.

Priya and her mischievous classmates plant a fake love letter in Shanmugamani's desk. He misreads it as Priya's own prank and confronts her directly. The incident makes Priya a focal point of attention and triggers a cycle of further pranks.

Believing the letter may have been written by him, Priya starts to fall in love with Shanmugamani. He continues to see her actions as mischief and clashed with her, deepening the conflict between student and teacher. The dynamic draws the rest of the class into the unfolding drama.

Shanmugamani warns Priya and submits the matter to the Headmaster, convinced she is at fault. Priya is suspended from school without a fair chance to defend herself. The suspension damages both reputations and compounds the misunderstanding between them.

Shanmugamani later realizes Priya's innocence and apologizes for the misjudgment. With reputations tarnished, Priya proposes that they marry so they can start anew together. The idea unsettles Shanmugamani, who still fears the ethical implications of a teacher marrying his student.

Priya asks for a Transfer Certificate and stops her studies. She then moves into a paying guest near Shanmugamani's house to stay close and press her case. Despite her determination, Shanmugamani remains firm about the professional boundary.

To escape Priya's persistent pursuit, Shanmugamani marries Deivanai, a girl from an orphanage. Priya is shocked by the turn of events, reshaping the power dynamics in the household. Deivanai begins married life with hopes of compatibility, though tensions linger.

Shanmugamani envisions a wife who fits a certain ideal, but Deivanai does not fully meet that image. She nevertheless tries to live up to his expectations and support him as a good wife. This contrast creates a quiet strain within the marriage.

Priya, understanding her position, secretly helps Deivanai with cooking, English, and other skills to attract her husband. Deivanai grows more trusting of Priya, even as Shanmugamani disapproves of Priya's continued presence nearby. The trio's entangled relationships complicate everyday life.

Priya keeps trying to win Shanmugamani's love, while Deivanai stays supportive. Shanmugamani issues a clear warning to Priya to stay away from their life. The atmosphere becomes tense as boundaries blur between friendship, romance, and duty.

Deivanai overhears their conversation about Priya's schemes but does not react openly. Instead she takes Priya to the hospital for a check-up, showing concern despite the mounting tensions. This moment foreshadows Priya's fragile health.

Medical checks reveal that Priya is battling cancer and has limited time left. The news reframes the conflict and underscores the urgency of Priya's final wishes. Deivanai and Shanmugamani must confront the reality of her illness.

Deivanai urges Shanmugamani to marry Priya so her last wish can be fulfilled. Though reluctant at first, he agrees, moved by Priya's suffering and the prospect of fulfilling her final desire. The plan centers on honoring Priya's life rather than dwelling on past conflicts.

Priya dies in the school, in her classroom while wearing her uniform. Her last speech, captured on a tape, praises Shanmugamani for upholding ethical boundaries between teacher and student. She entrusts Deivanai with her jewels and speaks of being born again as their child.

Shanmugamani and Deivanai place Priya's jewel on their newborn, believing she will be born again as their child. The scene closes on a note of reconciliation and continued memory of Priya. The family carries forward Priya's spirit through the child and the shared vow.
