For right or wrong, for good or bad Karan married Tanya. She is his wife that is the reality. But after Nandini came back from the coma he should have made a clear choice between the two women. But instead he strung along two women in this emotional roller coaster. No matter whose fan you are you can agree I don't think either women deserved that.
Now Nandini has moved on by marrying again to Aseem or so we think. All the romance they showed between Karan and Nandini in todays episode. What is she trying to prove, that she is also in love with two men. Nandini shouldn't string along Karan and Aseem. She must make a clear choice, if she married Aseem she should just move on. She shouldn't do to Aseem, what karan did to her.
All in all what I am trying to say Everyone should move on. Lets get a happy ending to the story. Tanya loves Karan, let them be happy. Aseem loves Nandini, even though I don't like the actor who is playing Aseem, I think the character is a nice guy so let them be happy. 👏
