You always lived in a household where there was violence, cursing and etc. There was never two words of sweetness or peace in your house

Your parents died when you were a kid. And you lived with your grandma and your uncle, Min-jun. He is 35. he was an alcoholic person. He is like a criminal. A total violent and ruthless person.

Your grandma loved you so much, she was really sweet and kind but she died some months ago After you turned 20. So you were left with only Min-jun now
