Collar ni Kuchizuke

College student Miki Kuroda carries the lingering scars of a traumatic past in which he was forced to wear a collar. Because of this painful history, he has developed a deep aversion to Dominants, doing everything in his power to keep his distance from them. Yet, despite his psychological resistance, his body instinctively craves submission. To cope with his overwhelming and unrelenting desires, Miki relies on reading erotic novels as a private outlet to manage his urges. His carefully guarded routine is disrupted when he takes a job as a babysitter and crosses paths with Moriya, a Dom. Though deeply unsettled by the encounter, Miki pushes through his confusion and manages to complete his duties. Shortly after, however, his suppressed instincts betray him, and he suddenly slips into heat. In his desperate attempt to find relief, Miki reaches for one of his erotic novels, only to realize too late that Moriya has caught sight of his highly compromising state.
