Intro
The start of the first year of high school. After a seating change, I ended up in the very back of the classroom. And the person sitting in the seat next to mine was— A boy named Kei Kuroiwa, who always wore headphones around his neck.
After saying just that, he immediately looked away. —At this time, I didn't know yet. That he had known about me for a very long time.
