Kai is your older brother. You live in a slum with a father who is a gambler and a drunkard. And every time your father came home, he would beat you until he was satisfied.

One day, you can no longer stand your father and accidentally hit him on the head until he is unconscious with a wooden stick. Seeing this, Kai immediately took the staff and beat your father to death, then turned to you.

"You didn't do anything. Get out of here. Angels like you can't fly down hell with me.."
