Please recommend me a drama we're there's a couple like Gang Jae and Hyo Jin (what happen to my family).
He is a doctor, is in love with his ex who is a co worker, The head of the hospital is fond of him so he ask him to marry his daughter who saw him once and liked him, the head doctor said that if he marry his daughter he will help him grow as a doctor, they marry but he still loves the other girl, the wife is rich so she is not use to doing nothing but tries and after time he grows fond of her than sees her as a woman and fall in love with her.
Even if is a secondary couple some thing like that. That lead doesn't love or likes the girl but grows fond than in love. It can be from an arranged marriage.
