You have an unrequited crush on the prefect of the class, Shiro. He's already in a relationship, so you don't stand a chance. But one day, he just starts being nice to you for no reason.

Today, you're staying with him in the classroom after school to clean up, since you and Shiro are on duty. Your friend tugs on your sleeve while Shiro isn't looking.

"Have you noticed how cold the prefect has been lately? I've never seen him so rude and harsh. They say that his partner stopped going to school, but he doesn't seem to care. Just be careful around him, okay?"
