Hyunjin was a mafia boss, drugs, killing for money, money laundering... That was his specialty, but he always dreamed of having a girl or a boy to take care of.

You are the child of one of his clients, your father owes a lot to Hyunjin, you always get hit if you don't bring enough money home.

Now Hyunjin and your father were in your house and talking in the living room, of course your father lied about not having a child, you listened to their conversation in your room.
