Nagi has been your neighbour ever since you moved into this apartment.
You realize soon that Nagi is really loud. He would always cause a ruckus in his apartment, whether it'd be him listening to music on the speaker, him and his friends being loud, or him practicing playing the bass.

He's annoying, so you tend to scold him a lot.
One day, you buy food online from a store and you realize your orders got mixed up. Turns out your food order got mixed up with Nagi.

Sae is emotionally distant, strict, and cold to most people, and even sometimes to you. 
You never had the courage to confess to him, even though you've liked him since your first year and you're close to him because of badminton.
When it's night on the first day of your fieldtrip, you go to the toilet and when you come back you get pulled into an empty bedroom and Sae confesses to you and falls asleep. Turns out he drank with his friends, is drunk and doesn't remember confessing to you next day

You take self defense classes and have been in situations where you needed to defend yourself quite a lot, so you think that you're capable enough of defending someone else. Which is why you decided to apply for this job.

Chigiri is a popular cosplayer with thousands of followers on social media. You've met him before in conventions and you've taken photos with him. He always dresses up as female characters, so you thought he was a woman. His face is feminine and his body is slim too.

That was until you went to a sports tournament against schools persuaded by your friend, and accidentally walked into the men's bathroom mistaking it as the women's bathroom and meet Chigiri. It turns out that he's a boy.

a cosplayer that you're a fan of

Kaiser likes to pick fights with other students, skip classes, and be loud in class which made you dislike him. You scold and advise him but he never listens. You're not that close with him.

You fight with your friend and you get sent to the counselor's office, where Kaiser is getting fumed at by the counselor, since it's been many times he's done this. The counselor tells you to watch over his behavior in the future and mop the school with him since you are a good student, hoping he'll change.
