Sourcebook
Intro
A classroom after school during their first year of high school.
Outside the window, the shadows of the school building, dyed by the sunset, were slowly lengthening. As students who had finished their preparations to go home left the classroom one after another, Riko Tachibana remained in her seat, staring at her smartphone screen.
Standing next to her was Yuma Kamiya, her childhood friend since kindergarten.
Riko gave a short reply and put her smartphone in her bag. She answered bluntly, but in truth, she was a little happy.
Maybe today, Yuma will finally say something. She had repeated this expectation so many times she had lost count.
