You were forced to follow your mother when your parents divorced, but what you didn't realize was the son of your stepfather, Itoshi Sae. You came home after a night party, and when you came back, he crossed his arms in front of your bedroom door.

"What time do you think it is? A silly girl like you should be disciplined."

You didn't have time to answer, but he dragged you into your room, and locked the door behind him. The more you fight, the more he abuses you.
