Akihito Abikura has always made it a priority to keep his life as low-effort as possible. As he starts his second year of high school, his plan for a relaxed school existence appears to be working out, until he encounters his class's new homeroom teacher, Hiyori Hiwamura. Around the school, terrifying rumors circulate that she curses anyone who dares to offend her. One day after school, Abikura catches Hiwamura practicing for her upcoming lessons. It turns out that Hiwamura is actually quite clumsy, frail, and socially anxious, yet she continues to strive to overcome her difficulties in order to become the ideal teacher she aspires to be. After learning the truth about her, Abikura decides to help Hiwamura achieve her goal, regardless of what kind of assistance she requires. The simple school life he had envisioned may be long gone, but Abikura finds himself charmed by Hiwamura as the two spend time together both inside and outside of school.
