During his childhood, Atsushi Arisawa fell for Masami Shibata, the older neighbor who lived next door. Even after Masami left town, Atsushi kept writing letters to his former crush. When he was about to enter high school, he chose to enroll at Jougaouka High School—a place with a notorious reputation—because Masami had become a nurse there.
Yet upon arriving, the man in the infirmary was nothing like the gentle boy he remembered and seemed to have forgotten him entirely. While Atsushi struggled to understand this strange encounter, he began to value the sharp‑tongued nurse for who he truly was.
