Sawaranaide Kotesashi-kun follows Kouyou Kotesashi at Seiwa University Affiliated High School, a sports powerhouse where elite athletics and relentless pressure shape everyday life. A gifted masseur who dreams of becoming a sports doctor, Kouyou is determined to win a scholarship to medical school and build a future his family’s finances could never support on their own. To cover his school expenses, he accepts a live-in job in the school dormitory, expecting little more than maintenance work and a place to stay. The position quickly proves far more complicated.
Instead of a quiet residence, Kouyou finds himself living with a houseful of highly talented but quirky female athletes, including Miyuki Hongou, Aoba Kitahara, Izumi Sumiyoshi, Aroma Kusunoki, and Chiyo Sayamagaoka. Each has her own routines, demands, and personal burdens, and Kouyou becomes responsible not only for keeping the dorm in order, but also for caring for their physical condition and emotional well-being. His massage skills are essential for helping them recover after intense workouts, stay focused under constant strain, and keep training without falling apart. With cramped living quarters, nonstop practice, and the awkward intimacy of dorm life, the series turns recovery sessions into the center of a fast-paced school comedy about ambition, discipline, and the messy bonds that form when everyone is chasing the same goal.
