Later on, Avi runs into Milli on the golf course, and they start to talk. Milli tells him that a stupid old man ruined her painting and points out that it was Balraj; but Milli doesn't know that Balraj is Avi's father and Avi doesn't tell her. They start to have lunch together and hanging out while slowly falling in love with each other.
When Milli comes home, she is visited by her childhood friend Rajat (John Abraham). She tells him that she loves someone (Avi), which devastates Rajat because he is also in love with her.
