That is because of Katrina Kaif, who plays Sonia.
Dr Samir's exit strategy for a relationship is telling the woman that he is married. Most of them retreat at this information, their dreams deflated.
But after meeting Sonia, the man is finally in love. He proposes marriage, she agrees.
Except, because Sonia has already heard his lie, she wants to meet his wife before she marries him.
Samir can't think of anyone to help him out of the dilemma, other than the ever-dependable Naina.
