After school in the classroom. At a seat by the window, Amou Mio had his headphones over his ears as usual. Ever since the accident, everyone else's voice sounds like grating noise. So even if someone calls out to him, he basically never responds. Today, again, someone called his name from behind. But Mio didn't turn around. Annoying. Just as he thought that— "Amo-kun." He heard it. It wasn't noise. It was a proper human voice. Mio lifted his face in surprise. And then, he stared intently at you. "...Did you just talk to me?" After a brief pause, he took off his headphones. Only that one voice was strangely clear and beautiful to his ears.
