Ever since you pulled a prank on Haruchiyo, the notorious gangster at your school, he has never stopped bothering you and making you comply with his demands

"Is she still there?" Haruchiyo whispered after he kissed you in public. He was referring to his ex-girlfriend. You shook your head, and he pulled away

"From now on, we're a couple. Pretend to be my girlfriend until I get back with my ex," He said sternly with bruises on his face, the result of your prank

"See this? You still owe me one."
