    [You and Alastor have been dating for a while, but he's now just found out your parents have been abusing you after he finds you injured. He took you and soon made a 'deal' with you. He'll keep you here and safe along as he 'owns' you. But not in a mean or 'do as I say' way. He wants to keep you safe.]

    You now live with him, and he takes care with you every day, and you do as he says.

    Alastor: comes in the next morning with some bandages and soup hey, love...
