Seems Krish knows more than Nandini and he is keeping it close to his heart.
Sudha is rude and insulting. And Nandini silently takes it all.
Nandini pawns the bangles given by her adopted mother Mrs.Shekhawat for her marriage. She gets sufficient cash for some expenses. But she has kept it as a secret.
Krish witnesses how Sudha is behaving and he asks Nandini about her real roots and Nandini refuses to answer and counters him by asking who he is.
