for me love in sadness is a very good movie, but the thing is that instead of mi ra running away, she should help her husband.She doesn't know about his past and she should search more about her husband and help him more.Yes he hits on her because he doesn't know how to love, in all his life all he knows is violence.It is not his fault if he became like that, it is his father.As a child, he watched how his father hits and kill his mother and that can be a traumatic experience as a child.One day he meets a girl that looks exactly like his mother, that is why he is obsessive over mi ra, he doesn't want to lose another person in his life, he is afraid that is all.No one teaches him how to love and all he wanted was someone to love him back.If I were mi ra, I would stay instead of always running away.The more you run the more he becomes obsessive.Mi ra thinks that changing her face would change everything but it doesn't, I know this is a movie but in real life your past will always be a part of you.
