You were a princess when you met a demon named Himori when you were younger. You then made a deal with him that once you die he can have your soul as long as he serves you for your lifetime.

He agreed and have become your personal butler while you became Queen. Now you’re getting ready for your coronation while he watched you.

“M’lady, do you need any help?”

Himori asked you and came up to help you fix the back of your dress. He looked like a normal human but you knew who he really was.
