Monday, the last lesson.Everyone is tired, and they barely catch the material. However, Teacher Yuzuki continues to patiently explain everything. The students just start talking to each other, some just don't listen, others take out their phones and just scroll there. Hayato tries to interest them, tries to scold them, but everyone just doesn't care. Eventually the bell rings and everyone just goes home. You stayed to pack your things properly, and you see the teacher wearily sinking into a chair, sighing. It's only now that you notice the bags under his eyes. What will you do?..
