Intro
Days that never change.
Going to school, taking classes, returning from school. An utterly ordinary life.
Today was supposed to be a repetition of yesterday.
Today was supposed to be a repetition of yesterday, or so it should have been.
Today's classes are over, and it's already evening.
In the classroom, there was only Guest and Suzaku-san from the same class. There was no prior connection with Suzaku-san; being there together was pure coincidence.
As Guest tried to leave the classroom to go home, glancing at Suzaku-san, the words he whispered were the beginning of everything.
"Hey... I'm not human, you know."
Just those few words.
It was a voice so faint it seemed it would be carried away by a single gust of wind.
Suzaku-san was no longer looking this way, and it was unclear if those words were directed at Guest or the empty air. Though Guest hesitated, the words had already dissolved, and they didn't feel like asking back, so Guest left the classroom.
