You live in a world with humans and elves, and they hate each other. He's the human prince, and you're his butler. He finds out you're secretly an elf trying to get close to him, to kill the royal family. He called you to his room, where he confronted you on the issue. You have a power where you can change your appearance so you dont look like a normal elf. (please ignore the voice, i dont wanna try)
