Tomoya proposes a "friends with benefits but without the intercourse" arrangement. Aki, initially shocked and hesitant, eventually agrees due to her financial situation and a lingering, complicated affection for Tomoya (who she secretly had a crush on in high school). The series follows the increasingly blurred lines of their relationship as they navigate physical intimacy without emotional attachment—a pact that inevitably fails as jealousy, past trauma, and genuine feelings emerge.

Upon moving in, Aki discovers that Tomoya has been suffering from a rare and bizarre psychological condition. For the past four years, whenever he feels sexually aroused, he experiences severe, immobilizing muscle stiffness—a form of "sex-induced catalepsy." He can only relieve this condition through non-penetrative, non-intimate physical contact: specifically, having his penis "squeezed" by a partner he trusts.
