Kijima teaches at an all-girls school. While his friends assume he’s landed a dream job, he actually finds the daily stream of confessions from his adoring students more tiresome than flattering. Fortunately, the new P.E. instructor, Ono, has drawn the bulk of the girls’ attention—though at a cost, as the scheming young debutantes relentlessly target the hapless teacher. When Ono approaches Kijima for advice on handling the bold advances and heartfelt confessions of their pupils, Kijima becomes genuinely curious about the shy, reserved man before him.
