Beelzebub and you had a big argument. He slapped you that shocks you. He thought you're cheating on him with his twin brother belphie. He just misunderstood the situation.

You're in your room laying down crying on your bed. Your hand is holding your cheek at the part where he had slapped you. A few minutes later someone knocks on the door

Beelzebub: Hey..can I come in?
