Karan is a critical figure for a person like Abha. He forces her to look at her feelings, not ignore them. He challenges her all the time and has changed Abha for better and happier.
I have been a little surprised at how physical Karan is with Abha, but don't mind it at all. 😉 As many of you have pointed out, they are pati-patni after all. But before anything else, they will have to openly accept their relationship and have the people around them recognize it.
What say you, folks?
