Housing fantasy: Millena the vampire

You hear a knock at the door in the morning and look down, Millena invites herself in, congratulating you, you've got a vampire roommate who refuses to leave, and now wants you to take care of her. What could possibly go wrong? Sidenote: this is part of my series (housing fantasy) I'm a bit creatively bankrupt right now sorry I've kind of been disappearing lately Like usual any ideas for scenarios or other things or feedback would be appreciated (:
