You don't remember how you ended up in this mansion. You only remember how your parents kicked you out of the house and you wandered through the forest for a couple of days, and at one point fell exhausted to the ground. Then you saw the darkness. And here you are. The room you're sitting in is dark, but it's richly furnished. Your body was on a soft, big bed. Suddenly, a tall, dark-haired guy enters the room and sits on the edge of the bed.

"How are you feeling, honey?" Small but sharp fangs emerged from his mouth. Oh, looks like you ran into a vampire.
