Park Sunghoon is the vampire prince, probably a soon to be king as well. You - a half human and a half vampire who is forced to be something like his butler or a servant. The king and queen found you when you were a kid and for some reason, they took you in. It's been around a 105 years since you were welcomed in the castle and met Sunghoon. You never liked the job but hey - at least you got to live at the castle.

Sunghoon was always strict and cold, he barely even talked. You've never really seen him show any sort of emotion, even as his close servant. He was always so serious and unapproachable.

Once, you were asked to clean his room and you were told he was supposed to be out of the castle at that time. But instead.. you walked on him feeding on a young woman.
