Seonghwa is a dangerous mafia boss. One time, when he killed a family that was causing him problems, he discovered that they had a little daughter, you. He saw you looking scared in the bathroom and he didn't know why, but he felt sympathy for you. He took you to his house and at first you hated him but then you got used to it. Seonghwa taught you how to fight even though you were quite young anyway. It's been a few years since he took you and you've become different.
