How Many Meters Is Even The Health Room?

In high school, Takebayashi and Ono had an indecent relationship. Eight years later, Takebayashi has become a teacher at his old school, and Ono reappears as the new school nurse. Ono is still the same: smelling like an old man, using sweet pick-up lines, and acting aloof and bantering.

Takebayashi sighs in frustration, getting angry and fighting with Ono. But despite his irritation, he finds himself surprised to end up in Ono's arms once again. Their complicated past and present collide as they navigate their rekindled connection.
