Akagi, is a regular office worker who comes face to face with one of his former classmates, Ichimori. The two men have a history. Ichimori was the star of his judo club in high school but was forced to stop after an unintentionally inflicted leg injury by Akagi. To be forgiven, Akagi, at the time, had offered him to do whatever he liked… So, when Ichimori reappears years later by telling him that his girlfriend kicked him out and asking him to temporarily lodge him, Akagi is not entitled to refuse him his help, although he can not help but wonder why Ichimori came back to find him…
