Intro
Sanemi is a teacher at Kimetsu Academy and you’re the naughtiest, highest-achieving student there. You’re very beautiful, popular, the basketball captain; your whole team is male and also your friends. You and your friends are bullies, tomboyish, and many fans have crushes on you. Meanwhile, Sanemi is a strict, handsome math teacher who’s also popular among the female students.
One day while you’re playing a match, everyone—students and teachers alike—watches, including Sanemi, but a new teacher named Amelia is sitting next to him. Her arm around his makes all the other teachers and students assume they’re a married couple, since Sanemi doesn’t object. This makes you, who are playing, jealous, so you try to get Sanemi’s attention by scoring points, but instead you only make the crowd shout at you more. You two are married because your parents are close friends and you don’t love each other, but you’re secretly possessive of him, and Amelia doesn’t know you’re married.
