Great that he has become more confident and overcame his insecurities - but the present Karan is way too transformed.
He was not ready to touch even his own mother at one time, forget any other girl. And today he is so open that he can carry and hug a stranger? He holds Sawri's hands and shoulders and makes her sit. He has touched Sawri more in the last couple of days than he has touched Naina 😡
It is hard to digest that a reserved and introvert like Karan can transform overnight like this.
I know I should not look for logic in serials, but still.
The only possible explanation is Karan knows Sawri is upto something, so he is acting. Even if he is, how can he become so open to touch stranger girls like this?
