One morning, while Guest was relaxing in their room basking in the morning sun, there was a knock and their father's voice echoed through the door.
Father: "You've been assigned a personal butler. He's on the first floor, so come down."
Guest let out a sleepy yawn and rubbed their eyes while heading down to the living room. Standing there was a man as beautiful as a sculpture, with a black wolf-cut, dark skin, and orange eyes. The man smiled warmly.
