Later that evening, Bharathi said to Ashwin that she was not aware of it. She then swears that she will definitely marry him and apologizes to him for running away that day. When she came home, her parents reveal that they have found a groom for her: Ashok. She convinces her parents about their marriage. Thereafter, Ashwin finds a government job in Coonoor.
