Because anything that happens to anyone in that family becomes Dhara's business, whether or not the other person wants it to be.
Krish seems to have not only acquired another wealthy wife but also extremely loving in-laws who treat him like their son. His attitude, lack of guilt and victim play make me want the girl to be someone who shows him what torment and agony truly are.
Also, did they forget he is still just supposed to be in his late 20s. Why give him that particular look. It makes him appear a lot older. It's not even as if he lived a hard life over the years.
He looks to me like a crook..or even a serial killer who is on a hunt for closure..đ€Ș
