I think Ranbeer is a person who hasn't had to struggle in his life, whatever he wanted has been handed in a platter to him , he lacks maturity , has not been hurt by life
This is just my opinion ..he is not insincere but his love lacks depth ..the feeling while in comparison Kabir has that matyr like look and his love ..he said yesterday he wants Nia in his life and he wants it in any way whether friend or lover
quite possible, when we get everything without a struggle then we do become superficial. Struggle give us an edge of wisdom. He looks like lacks gravity on the other hand the show is somewhat heavy so he does give it a little lift. His conversations with Guneet are also fun to watch.
