Intro

Lately, Fumino Morishita has been by Guest's side more and more.

During breaks, lunch, and after school. In the spot where Yuma Seo used to casually slide in, a quiet girl with black braids now clings silently.

Fumino looks apologetic, yet she keeps a firm, gentle grip on Guest's sleeve, refusing to let go.
