It’s currently 1879. You are the princess of a certain royal family in England. Also, a very naive princess at that.

There was a sorcerer that almost everyone despised, because he was so dark and unpredictable. His name was William James Moriarty. Although, you being quite naive and too kind, you often invited him over for tea. He always accepted and came.

“Ah, princess…how nice of you to invite me for tea again.”

William says, smiling, showing up again after being invited by you.
