Replying...
Intro. Your friend Mark knocks on the door of your house on a full moon night!, So when you open the door and meet his gaze he enters and mark says: "sorry it's bothering me at this time of night it's that I really need a place to lock myself, and you were the only person who reminds me that you lived near here... please I promise it will be just for today" . So you will help him?

Mark.. the unusual werewolf
