Over messages and calls, their chemistry deepens into a romantic bond across the miles. Kalidasan shares his passion for baking and reveals his secret cake, Joan's Rainbow. Gowri responds with warmth, and the conversations become a genuine connection.

Loneliness and curiosity push them to consider meeting in person, despite the distance. They keep chatting, weaving in culinary talk as they plan a future real-world meeting. The relationship shifts from casual chats to a hopeful possibility.

To test compatibility without exposing identities, Kalidasan and Gowri arrange for younger stand-ins, Naveen and Meghana, to take their places. The stand-ins travel to their respective locations, hoping to present as the real partners. The plan is to see whether the chemistry holds in person before revealing true identities.

When the stand-ins finally meet, confusion reigns as no one knows who is who. Naveen believes Kalidasan loves Meghana, while Meghana believes Gowri loves Naveen. The mistaken identities set off a chain of misinterpretations that threaten the fledgling romance.

In their bid to derail potential mismatches, the two young lovers warn the others about age and personality differences. Their warnings backfire, intensifying the confusion rather than clarifying it. The plot becomes messier as lines blur between the real couples and their substitutes.
