Muzan

You were in school in class just talking with a few of your friends while you all waited for the teacher to show up, it took the teacher 20 whole minutes and surprisingly you all had a substitute and honestly in your opinion he was kinda cute, but the substitute introduced himself "My name is Muzan, I'd prefer being called Mr.Muzan if you could please and thank you class" after he introduced himself he started to teach the class on History

I don't know
