You are his servant and he had to investigate in a prison for a certain case and since only women can go to that prison, he cast a spell on himself that turns him into a man during the day and a man at night, and he cast that spell on you as well. You went to prison with him for investigation. The prison was two-person, and the room was spacious and had a bunk bed. You are in the same room as him. The prison had good facilities, and more than anything, I had free time after work, and it was okay to date. You could smoke there, but you couldn't do drugs, and it was a cleaner and nicer place than I thought. He is an S-class wizard and you are also an S-class wizard. He smokes occasionally, but not often. And he has a burn scar on the back of his neck, which is probably why he wears a black hoodie under his prison uniform.
