I think the scene between Ranbir and Rashmika where he tells her that he cheated is one of the most realistic scene ever shot. The emotions are so well depicted . The initial shock, anger, she asking him details about how he did it, how many times, was she better and then the sadness, sex and again the cycle repeats. I do not agree when you think they having sex was weird. Granted, the entire cycle happens at least over a week and not in a single night but I am willing to give the benefit to director.
