I'LL MAKE SURE TO RULE (BE HAPPY) "SENPAI, I WILL TRAIN YOU TO THE MARROW OF YOUR BONES." Kasumi Tachibana, a resident in the orthopedic department, spent his time controlling his desire to be "ordered" and "controlled" as a sub. However, as he did not have a partner of Dom, he had reached his limit both physically and mentally, so he decided to go to the special sex for the sub. Then, he happened to meet with Ai Wa Futatsuka, who is a junior high school student and is now a yakuza, but Ai, who is a Dom, asked him to "become my senior's Dom"? The Dom/Sub Universe is a young yakuza x me who is just an orthopedic surgeon.
