Chapter 5
From xiaojiangworld: As a 3rd year and the sole member of the gardening club, Sakaki is taken care of by Matsumoto during his rehabilitation time until he can go back to being a regular of the baseball club. When Sakaki frees Matsumoto from their master-slave relationship, Matsumoto refuses. The reason… is because he has dirtied Sakaki in his mind countless times.
Chapter 2
Matsumoto is the ace pitcher of the baseball team. Sakaki is a third-year upperclassman who looks after Matsumoto like a wounded dog, having him do his biddings from time to time. Matsumoto finds himself tamed by Sakaki, the lone head of the gardening club, during his rehabilitation period, upon which Matsumoto is allowed to return to the regular lineup. Sakaki congratulates him and tells him that he will be released from his errandboy duties, leading Matsumoto, who's defiled Sakaki many times in his mind, to refuse being let go.
