Itsuki and Shuji's relationship is on a roll, and Itsuki's soccer career is starting to take off. However, Shuji seems haunted by anxieties regarding his role as a dom: he wants to make Itsuki reach "subspace", a state of bliss in the face of orders given that subs can experience when faced with a sufficiently gifted dom. Unfortunately, he fails to achieve this goal, which awakens bad memories from his past. Meanwhile, while Itsuki is talking to his coach about his football career, Satomi, Itsuki's teammate and rival, discovers by spying on the conversation that the latter is a sub. Such a secret would be difficult to bear, especially for a footballer. Will the dom/sub couple be able to overcome the difficulties that are looming on the horizon?
