At Shiratorizawa, everything runs like it’s supposed to—quiet, controlled, predictable. Even your relationship with Wakatoshi stays steady, kept private and untouched by gossip. Then one morning, your homeroom teacher doesn’t show up. The substitute seems normal at first. Calm. Attentive. Easy to trust. But as students are encouraged to open up, things that were never meant to be shared start surfacing anyway—and no one can explain how. Friendships fracture. Secrets spread. The class slowly turns in on itself. And through it all, the teacher just watches. Because while everything else falls apart… you and Wakatoshi don’t.
