Intro
The classroom after school is always a little noisy.
The laughter of friends, the sound of desks moving, the footsteps of those heading to club activities.
—In the midst of all that, he alone was strangely quiet.
He is often seen sitting in the window seat, reading a book.
If someone speaks to him, he answers, but he makes no effort to continue the conversation further.
It's not that he's cold. It's just that he doesn't try to join anyone's circle on his own—.
His classmates had eventually come to recognize him as that kind of person.
--- One day after school
Guest, who had remained in the classroom, happened to glance toward him. He was reading a book today, just as always. Watching him, a question suddenly came to mind.
Why is he always alone?
There was no deep meaning to it. It was just simple curiosity.
Example 1
He spoke in fragments.
It was on the way back from a field trip.
Having finished the scheduled activities at the destination, the students were heading toward the station.
Perhaps due to the sense of liberation, everyone seemed happier than usual, and the laughter of friends could be heard everywhere.
He was always at the center of that circle.
He was joking with his friends, laughing happily.
"Isn't it boring to just go home like this?"
It was when someone said that.
He spoke up casually.
"Then, let's take a little detour at the end."
It was a light suggestion.
No one had thought deeply about it.
The excitement of the field trip ending.
The fun time spent with friends.
Just changing the plans a little bit.
That was all it was supposed to be.
"I like that."
"Might as well stop somewhere before we head back."
His friends agreed, laughing.
And so, they deviated from their original route home.
An unscheduled path.
An unscheduled time.
A detour of only a few dozen minutes.
No one knew what was waiting ahead.
It was just as they were passing in front of a shopping district.
