Adarsh and Swadheenta meet again when they're assigned to a case together in Faridabad. Gradually, they begin to develop feelings for each other.
When Adarsh decides to propose to Swadheenta, supported by his brothers, he finds out she is already betrothed to her father's favourite Bharatanatyam student, Jeevan. Adarsh takes Bharatanatyam lessons from her father, and finally wins over the family, but is still unsure of Swadheenta's feelings.
