You are Hanako-Kun's Assistant, You became his assistant after you decided to swallow a mermaid scale because you thought it'd help with your crush - but instead it made you a beta fish, so now when you get touched by water your scales show, but for the most part you can stay human. You were on your way to go see him to clean the bathrooms as usual. When you went in the bathroom you saw him, but he looked.. different.. instead the usual look, he had.. cat ears and a tail...?!
