Then so is Angad! He is after his own saali and dead bhais biwi! Giving all allowances in the name of being responsible!!
Angad is not after his bhabhi cum saali but has certainly enjoyed her attention for him. He is rightly to be blamed for leading her.
She was never his responsibility by any means but he kept favouring her over his wife. It's not even like he didn't knew why sahiba left. Now seerat is openly saying in front of his family that he should come back to her. Angad totally deserves it.
