This movie is all about the change of work of gender ie male is getting into work of women and women is getting into work of male.
As the story started with Ki & ka in which kareena kapoor played the role of Successfull women in her career. And later one she want to become the ceo of the company.BUt she refuses to marry as she think that marry is only a bullshit owrd for him.and after marriage she will do work as other housewives.
Whereas kabir which is played by arjun kapoor is topper of iim-b and son of a very succesfull bussinessmen.he want to like his mom.I think you should watch movie if want to know more story.Overall its is just a one time watch movie.
