Did some introspection on the characters involved in the movie.
Both sharukh & rani character have something in common
Both have nothing much to do.. kind of loosers in life looking for some adventure and change. Both having inferiority complexes and looking for a way out..
If both the characters had been busy with their respective careers, lives. they would have found less time to find faults in their spouses, picking up fights. This seems to be an ideal case of empty minds devils workshop.
I am bound to think, considering their picky nature. They would end arguing. figthing with each other (i.e. rani and sharukh after getting together).. and then where’s the end.. both start looking at more partners.. to give them a temporary relief.
one has to search happiness in their lives.. there is happiness in seeing your other family members happy... and not just in happiness for the self.. and not go around looking for other partners to satisfy lust. once you have children, children’s happiness also counts. you have to sacrifice a lot.. its not that you marry for 5 years.. have children..a nd suddenyl realise you dont love your partner but someone else.
to me it looks like a simple excuse for lust in a extra marital marriage.. people having no control over their action, and making a story around it.
