Aarathi, best known as Aashi or Radhi, is the only daughter of Revathi and Prashant. She is a woman who toils day and night as an auditor. As a daughter, she wishes to fulfill all her dreams, which always revolve around her parents. A pulviophile (rain lover) within the heart and a silent yet audacious woman out. She is steering clear of every matrimonial affairs for now and needs to settle down financially and set her heart on rain for peace. On the other side of the tale is Vishnu, a professor in the science stream. He is a fun-loving yet well-disciplined man who can not tolerate indecency. He is a present bibliophile and an ex cinephile. Currently, he is proving to be a good son by aligning with whatever his parents say. He is their firstborn and has a younger sister and brother. On a cloudy day, when Aarathi returns home dizzy and weak from work, her parents decide to send her off for a 2-3 week-long vacation for her well-being. After several refusals, Aarathi finally agrees to take the vacation and ends up booking three train slots. But the next morning, the two people traveling with Aarathi were not her parents. Who were they?
