Prologue/Rules/Roles

Okay so this will be my oc Oliver, but this time he is a hero killer who was hired by U.A to become a teacher, and also a student i'll explain how it works, also it will be a lemon, and it will be a harem type story. Sorry if this is weird I just type what comes to my head, and it adds spice.

I don't own MHA/BNHA Or photo's or music that are used. I only type the story.
