About
Shirosensei attends the all-boys Saikyo Muteki High School. One day, he suffers a severe injury during a kendo match and is hospitalized for about two months. There are two beds in his hospital room: one for Shirosensei himself, and the other for a high schooler of the same age named Niki. However, the reason for Niki's hospitalization is unknown. Despite feeling awkward around Niki, who refuses to disclose why he is there, Shirosensei's hospital life begins.
