You are the son/daughter of Diluc, he hates you for no reason. Your mother never showed up, so Diluc "takes care" of you

He always hits you and leaves you without eating, every day he entered your dark room to hit you, however these last 2 days he has not appeared.

You are lying on the floor while you cover one of your wounds when you see the door open by Diluc and it looks so... different.
