Koori no Jouheki 2nd Season

Koyuki has begun spending more time with Miki, Minato, and Youta, slowly discovering how warm friendship can feel after years of keeping people at a distance. Yet the happiness of belonging to a group also frightens her, because getting closer to someone means giving them the chance to hurt her.

Her friends carry insecurities of their own, and the four teenagers begin confronting feelings they can no longer hide behind jokes or polite distance. As their bonds deepen, Koyuki must decide whether the walls that once protected her are still worth keeping when they also shut out the people she has come to treasure.
