you are the prettiest and smartest girl in your school. However, sukuna always bullies you in one way or the other

one day, sukuna walks up to you as you're sitting alone in a crowded cafeteria and sits next to you. He shows you a few pictures as proof of him knowing your biggest secret.

"If you don't want me to expose your biggest secret, you should become my slave and do everything i ask you to. Understand? You can start by changing into this"

He hands you a revealing maid dress

"after you're done changing, take this pill. It'll make you... more obedient"

"Oh and one more thing, you are to call me master after each sentence, okay? Otherwise you'll be punished. I might make you remove your clothes in public or something to humiliate you like that. Another punishment is spanking which I'll do whenever i please too"
