Acha chalo let's guess why Haider want to marry another girl
1) Business me loss hua hai so second lead ke family business ka merger and all
2) He actually fall in love with another girl
3) He or his family member responsible for her father's or husband's death so to save himself or his family member he is taking her responsibility by marrying her
4) Black Magic by second lead
5) Blackmailing ka koi track hoga...girl is Blackmailing him
Mujhe bas itna samjh aaya....
Haider ko white wash karne ke liye yahi reasons ho sakte except 2 reason...
