This is actually a serious problem, not only for you but also for her and her family. Now she has to decide between you and her father who gave her this life and all she is because of her father.

But what was the reason that her father got heart attack, is it that he was shocked by her daughter's love affair or he didn't like you or it is cast problem ?
