He is Sameer's best friend and best friend are always for showing right path if friend is confused inon taking decisions.Right now yes Sameer is desperate to propose naina which I impulsive.. He should have given time to naina to settle down.Naina already have many things to handle.
i think there is only one way to make munna realise that he can't take decision on Sam 's behalf or can't decide Sam life all by himself... n the way is let swathi pretend n tell him that naina take a promise from her that she have to break up with him for naina 's sake... just like he took a promise from sameer naina take a promise from me...may be then he'll understand that some decision should be taken by own self..
