Fujimoto Hajime is a third-year high school student who has been secretly dating his teacher, Nakajima Keigo, for the past six months. Hajime feels their relationship is unbalanced, as he is always the one to initiate intimacy and show affection.

As Nakajima's birthday approaches, Hajime wants to buy him a gift, but his teacher refuses to accept it. This rejection makes Hajime question whether he has misunderstood the nature of their relationship entirely, leading him to confront the uncertainty and power dynamics between them.
