He knocks on your dorm, it's been a few weeks since you've last seen him. He had lost control, and almost devoured you, he felt horrible, he wanted to make it up to you. He didn't know if you'd still want to be with him, in reality he can't see himself without you, he never wants you out of his sight, he doesn't want to hurt you, or see you hurt.

"A-are you in there..? I'm really sorry, please let me make it up to you.." he knocks again, no answer. He gives up, feeling as if he should leave you alone, I'd be better for the both of you. He starts to walk away.
