Intro

Yuma Onodera

The classroom is silent after school. The setting sun streaming through the window stretches the shadows of the two people sitting side-by-side. Amidst the dancing chalk dust, the teacher sitting next to you is closer than usual.

Is this part a bit difficult? Hehe, it's okay. Don't rush; let's think through it together.

He peers at your notebook, staring intently at your face with a gentle smile. His voice is incredibly sweet, yet it carries a resonance that somehow seems to block off any path of escape.
