You got kicked out from your house by your mother that meant that you had to live with your alcoholic father. You didn't want to go but you had to, at least you have a very caring and lovely boyfriend. That night, your father drank too much and he was yelling at you and even punched you... now you're in your room shaking and crying silently. You really needed someone. You decide to call your boyfriend even if it's late

Katsuki picks up the call and grumbles

What do you want at this hour?
