In a picturesque hill town of Coonoor, Aravind, Jiiva, runs a cozy restaurant and charms guests with a light-hearted, flirtatious approach to life. Widely known for his playful persona, he navigates love with a carefree motto: Kavalai Vendam (Don’t worry). Yet beneath the easygoing surface lies a tangle of memories from a complicated past, tied to his ex-wife, Divya, Kajal Agarwal.
Flashback to a youth-filled courtship, where Aravind and Divya were inseparable friends who eventually pledged themselves to each other in marriage. Their bond, however, was tested by Aravind’s immaturity and Divya’s strong-willed nature. A painful moment occurs when Aravind’s mother scolds Divya, and Aravind fails to stand up for her. The hurt runs deep, and Divya, feeling rejected and unsupported, walks away, ending the marriage without giving him a chance to explain. The couple separates and loses touch, leaving a lasting ache that neither can fully erase.
Years later, Divya reappears in Coonoor, now living with her new boyfriend and poised to remarry. She arrives seeking Aravind’s signature on divorce papers to finalize the separation, but the sight of her stirs old emotions that haven’t faded. Rather than sign immediately, Aravind chooses to hold on to the moment, inviting Divya to stay with him for a few days so they can “reconnect” before any decision is made.
What follows is a boisterous, comic clash as two former lovers are forced to share a roof again. The small domestic puzzles—snide remarks, competing routines, and endless bickering—become a stage for a broader realization. Aravind’s mother, Mayilsamy, nudges them toward reconciliation, while friends tease him about still clinging to Divya. Divya tries to keep her distance, focusing on practicality, but memories—both tender and painful—rise to the surface in waves.
As the days unfold, Aravind rekindles the warmth of their past by cooking for Divya, coaxing laughter from her, and tending to her when she falls ill. A new dynamic arrives with Shanti, a friendly woman who secretly harbors feelings for Aravind, and her presence stirs a fresh round of jealousy in Divya, who refuses to admit her own lingering sway of emotion. The tension between past and present becomes a delicate dance, with every moment hinting at a future that could still belong to them.
Amid the humor and heartbreak, Aravind matures. He begins to understand that love is about more than fun and flirtation—it requires understanding, support, and compromise. Divya, too, starts to sense this change and questions whether their separation was truly the right choice. Misunderstandings flare again when Aravind’s light flirting creates confusion, leading Divya to briefly doubt whether he has truly changed.
The climax arrives when Divya is ready to leave for good and marry Shahid. In a heartfelt confession, Aravind opens up about his growth and his enduring love for Divya. He admits he was immature before but has learned a great deal from their time apart. His sincerity touches Divya, who realizes she still loves him as well. She calls off the wedding to Shahid, and the two choose to give their relationship another chance.
The film closes on a joyful, low-key comedic note as Divya and Aravind reconcile and begin again, but this time with a deeper understanding and a more hopeful approach to life. Aravind’s motto shifts from carefree abandon to a resilient, worry-free commitment to each other, embracing love with maturity and devotion. A light cameo by Yashika Anand as a swimming instructor punctuates the mood, adding a playful ripple to the story’s warm, romantic heartbeat.
