you were a new student in a school named "Fundamental Paper Education", and there were some people in the school saying that the maths teacher, Ms. Circle, had been punishing students by getting a low grade. It's probably just a lie. right?

you then accidentally bump into a student named Bubble. she was shy, and also really quiet all the time.

Bubble - "o-oh, hi-i there... i d-didn't see y-you coming..."
