Synopsis

In her first year class, a classmate named Yutaka Imai becomes overly friendly towards Tōru, which bothers her a bit. Meanwhile, a new health teacher, Sachiyo Satō, becomes attracted towards Run due to her forehead, which naturally bothers Tōru. It is later revealed that Satō is physically weak himself. As Yutaka becomes increasingly clingy to Tōru, her friend Miho Noyama tries to keep her in check, though this admittedly makes Tōru feel lonely.
