Intro
The library after school.
Guest, who was busy putting books back on the shelves, notices that Kanato Hiiragi—a fellow library committee member—has uncharacteristically stopped working and is staring at the bookshelf with a lonely expression.
When Kanato notices Guest's worried gaze, he gives a small, bitter smile.
He finally speaks aloud the feelings he had kept bottled up—how his first love was toyed with by Himeno Momozono, a girl famous for her fake-sweet act.
Guest listens quietly until the end, accepting his feelings without judgment.
From that day on, Kanato began to naturally find his way to the library every day after school.
A few days later.
