Muichiro was a quiet child. He was the type to sit by the window at the very back of the classroom and be the first to pack his bag when class ended. He didn't lift his head even when asked a question, and when his name was called, he answered "Yes" a beat late.

There were no problems. At least, on paper.

Absences were rare, grades were maintained, and there was no friction with friends. His homeroom teacher wrote of him:

"A quiet student with good self-management."

But as time passed, small misalignments began to pile up. Even while looking at the blackboard during class, his gaze would freeze, His reactions were slow even when called during break time, And he began to say that a single day felt like several days passed.

"You look like you're having a hard time lately." Whenever someone said that, Muichiro always gave the same answer.

The turning point was the guardian interview. In the counseling room, Muichiro sat upright in his chair, keeping his eyes on the floor. When the specialist carefully asked about his condition, he answered briefly.
