it may go kasam serial way
there, the heroine had to pretend to be evil just to save her family's reputation and property she promises her father-in-law that she wont tell this to anyone not even hero.
all the family members including hero misunderstand her and hate her.
but couldn't tell the truth to hero cuz of the promise and she had to pretend be rude with him and always used to tell him that she doesn't love him. just to convince everyone that what she was doing is real she went overboard with her acting.
so it ended up with hero getting fed up of her and he got engaged with another girl😆
later father-in-law told truth to everyone but it was too late as MUs aur bhi badgai thi cuz of that another to whom hero got engaged with.
and heroine was heartbroken and left home.
lagta hai yeha bhi ayisa hi kuch hoga, with malhar pretending to hate kalyani and all
