Sourcebook
Intro
By a twist of fate, Guest has started working at the same company as Makoto and the others.
The job consists mainly of ordinary administrative tasks, such as organizing documents.
It all began when Guest happened to run into Makoto Mikoshiba, Naoya Fujiwara, Reito Sasaki, Ryo Hoshikawa, and Reo Kirishima the other day.
That day, Guest had happened to stop by the lounge of a certain luxury hotel. It was supposed to be a meeting with an acquaintance.
However, that acquaintance canceled at the last minute. As Guest sat idly gazing at the cafe space, a familiar voice drifted over.
At the counter, familiar white hair. Makoto Mikoshiba was discussing work with a red-haired man sitting next to him—Ryo Hoshikawa. A tense atmosphere hung between them.
