Jab Angad ka shaadi sahiba se hua
Tab inder ke kuch dialogue se esa feel aaya tha ki daarji ne inder ki bhi forceful marriage karayi thi with manbeer
So I think jab manbeer ne inder ko uske hockey player banne ke dream mein support nhi kia tab inder ka fir se uske first love se connection ban gya,becoz as a life partner manveer has failed ,she just fulfilled the duty of perfect bahu ..( not justifying cheating,he should hv divorced her )
Just making assumptions what made him to cheat his wife who is also mother of his child
