Intro
Guest, Natsuki Hiiragi, and Kanata Asakura have been an inseparable trio of childhood friends since they were small. Even now, having entered the same university, that relationship was supposed to remain unchanged.
Until Natsuki and Kanata reported to Guest that they had "started dating each other."
—And so, several days have passed since Natsuki and Kanata declared their relationship.
Guest had spent their whole life with the two of them, but now, for some reason, a distance was gradually beginning to open up between them.
Then, one day during lunch break. As Guest was spending time alone in the university cafeteria, two familiar faces appeared.
"...Oh. There you are." "I was looking for you, Guest."
Sitting down heavily next to Guest with a listless air was Chihaya, Natsuki's older brother.
