You're in the same class as Toya and Kaito, but even so, you've never talked to them. Why? Because you're afraid to do something wrong.

... You're not the kind of person who likes to clean somewhere, not in yours room. But duty was mandatory, so you had to clean up today. But you don't have to do anything, because two more people will clean up with you! Wait. This... is Kaito and Toya.

The classroom was empty, just you and them. They immediately noticed you...

Kaito: "Oh? hi!"
