In childhood, both Shiva and Sai were competing for the same girl, Thiripurasunthari. Shiva gave her a rose and sweets and received a kiss from her, which made Sai extremely jealous. When Sai discovered that Thiripurasunthari had actually kissed him first that morning, it sparked a heated fight between the two boys. This incident created a lasting grudge that stayed with them into adulthood.

The childhood rivalry over Thiripurasunthari sets the pattern for their later competition over Sundari.

Shiva and Sai are invited to their school reunion years later. Despite their old rivalry and mutual skepticism, the reunion brings back shared memories and helps them rediscover their friendship. They decide to put their past differences behind them and become friends again.

Sundari is Shiva's ex-wife. They got married at some point before the story's present timeline, but their marriage ended due to misunderstandings between them. When Sai meets Sundari in Chennai, she doesn't initially know about Sundari's past connection to Shiva.

The fact that Sundari is Shiva's ex-wife creates the major complication in the love triangle.

Sundari develops genuine feelings for both Shiva and Sai. She confesses that she cares for both men and cannot immediately choose between them. This creates a difficult dilemma as she wrestles with loyalty and fears hurting someone she values, especially since both men are friends.

After a heated argument during a Chennai event where both men confess their love for Sundari, the situation escalates further when Sai's mother goes missing. Once she is found safe after a frantic search, the experience makes Shiva and Sai realize that their friendship is more important than their romantic competition. They decide to stop fighting over Sundari and instead support her happiness, letting whoever she chooses pursue a future with her.

The missing mother incident serves as a turning point that helps them prioritize friendship over rivalry.

During the chaos of the argument between Shiva and Sai over Sundari at a Chennai event, Sai's mother suddenly goes missing. This triggers a frantic search that lasts several hours until she is eventually found. The scare strengthens the bond between everyone and makes Shiva and Sai realize family matters more than romantic rivalry.

Thiripurasunthari, the girl from Shiva and Sai's childhood whom they both liked, returns unexpectedly. She has met Sai's mother and becomes part of a family gathering. Her return brings back old memories and creates a warm, family-like atmosphere. Both Shiva and Sai feel happiness seeing her back in their lives, momentarily setting aside their drama with Sundari.

Thiripurasunthari was the original source of their childhood rivalry, and her return completes their emotional journey.

The movie ends with a joyful family reunion where everyone is laughing and celebrating together. While the specific resolution of the love triangle between Sundari, Shiva, and Sai is not explicitly detailed in the summary, the focus shifts from their romantic competition to a more family-oriented celebration, with Thiripurasunthari's return bringing everyone together.

Shiva asks Sai to move to Chennai to help with his mother's medical treatment. Sai agrees to this request, and their decision to relocate together to a new city marks a new chapter in their lives. This move brings Sai closer to Sundari and creates the circumstances for the main love triangle to develop.

In Chennai, Sai meets Sundari who is a chef and his neighbor. Sundari's warmth and culinary talent draw Sai into a tender romance. This new relationship becomes a significant part of Sai's life in Chennai and ultimately creates the complicated love triangle with Shiva.
