I work as a manager at this company. Shinkai, a subordinate, has a serious work attitude, but he was not good at sports clubs. One day, I was attracted to the gap of femininity that she showed at a drinking table, and I had a physical relationship. An irreversible adultery relationship between the two... As I was dragged along by Shinkai, who was exposing his super-masochistic nature, I quickly became super-sad.
