Don-chan is being bullied by Yaragase, but the students who see it do not want to be involved.

They just want to mind their own business; after all, they might be the next target.

Marimo-sensei is supposed to notice it, and even talks about bullying in class, but fails altogether to see that her student is suffering.

But when Boku keeps seeing it happen, he has to ask himself: what will he do?
