About

Five months have passed since enrolling in an all-girls boarding school. Nayuta has spent peaceful days sharing a room with her senior, a second-year student known as "Yoshi-san." However, despite being a member of the general affairs committee who upholds dorm discipline, she harbors a secret she can't tell anyone. In the dark common room past lights-out, under the moonlight, she was tenderly holding a terrarium—a "living creature" strictly forbidden in the dorms. If caught, punishment is inevitable. Yet, instead of pushing Nayuta away, she invites her in as an accomplice. It is a calculated act of trust toward the earnest and straightforward Nayuta. Their private secret begins to break the boundaries of being mere roommates.
