On a sunlit beach, Hari and Sonia celebrate their engagement, surrounded by friends and family. The mood is festive, but Sonia’s mother watches with a wary eye, hinting at misgivings about the union. Elsewhere, Tamizh proposes to Roobini with a ring, while Hari shares with Viknesh that Sonia’s mother wants the couple to let their horoscopes steer the wedding. Hari’s father, a firm skeptic of astrology, dismisses the practice, and the clash between family beliefs and personal choice fuels growing tension as wedding plans move forward.
As preparations press on, Hari and Sonia navigate the friction between tradition and fate, with wedding plans looming large. Sonia starts dreaming of a Maldives honeymoon, but her mother strongly opposes it, warning about a water-related disaster predicted in Sonia’s horoscope. The elder’s concerns reach Hari, leaving him torn between heeding the warning and honoring Sonia’s wishes.
Tamizh pushes Roobini to meet his father, but she tries to dodge by asking Viknesh to stage a fake phone call claiming the wedding is off. Tamizh presses for the meeting anyway, and Roobini is stunned when his father begins laying out marriage plans. The moment triggers a heated conversation, and Roobini, shaken, confides in Sonia, urging them to work together rather than clash. Hari agrees to the horoscope reading but asks Sonia’s mother to keep the results secret from his father.
The couple travels to Singapore to personally invite Harini to the wedding, but their trip becomes tense as they argue about the Maldives plan. The argument spirals, and a devastating car crash leaves Hari and Sonia critically injured. Hari loses his memory, and Sonia falls into a coma. Grief-stricken, Sonia’s mother blames Hari and Hari’s father, and Hari’s father promises to keep him away from Sonia forever.
Hari is moved to Singapore, where Viknesh and Sukran accompany him. After his recovery, Hari’s father introduces a prospective bride, while Sukran arranges a plan to test the waters. In a twist, Viknesh goes to confirm a restaurant reservation and discovers Sonia there, on her first date with Mohandass. Sonia seems not to remember Sukran or Viknesh, and Hari arrives to find the scene tense and familiar, even as they struggle to recall each other. Easwary, Hari’s new date, arrives and helps ease the moment, allowing Hari and Easwary to walk away for a quiet talk.
Soon after, Sukran wonders aloud about the strange coincidence of their meetings and jokes about the possibility of dating Sonia if she were single again. He and Viknesh coordinate another encounter, and they end up crossing paths with Sonia and Mohandass once more. At the reunion, Hari experiences a growing yet unclear attraction to Sonia, even though their memories of the past remain tangled and uncertain.
Back home, Tamizh confronts Roobini about his abusive behavior, and Hari’s father and Harini stand up for Roobini. Tamizh’s emotions erupt into a sobbing, almost psychotic breakdown as he laments the end of his long relationship. Sukran and Viknesh pivot to press Mohandass to step aside, even conjuring an AI-generated “potential match” for him. The ruse works, and Mohandass agrees to back away if a suitable alternative can be found.
A final beachside reunion brings Hari and Sonia back into focus, and Mohandass arrives with Sonia to share the moment with their friends. The gathering culminates in a heartfelt reconciliation for Hari and Sonia, witnessed by everyone who cared to see them through the chaos. After the reunion, Mohandass asks for the “girl’s” number, and Sukran hands over a contact. When Viknesh asks whose number it is, Sukran merely smiles and says, “The number to Raaga.”
