As they spend time together, Santhosh believes fate has brought them together again and finally confesses his love. However, Nithya rejects him, leaving him heartbroken and forcing him to accept that their story is over. That night, Santhosh dreams that Nithya messages him from the bus and calls him to meet her. When he says he will never return if she stays silent, Nithya finally confesses that she loves him—but Santhosh suddenly wakes up, realizing it was only a dream. 12B is an emotional romantic drama about first love, hope, and the bittersweet difference between dreams and reality.
