Sachio Kurumizawa is a mouse beastman and an omega, working as a manga artist. He lives in constant fear of his editor, Shinobu Ukano, a fox alpha whose eyes always seem to size him up as prey. In a world where predator-prey dynamics and secondary genders dictate social hierarchies, a mouse omega is at the very bottom, both a sexual target and potential food for carnivorous alphas like Ukano. The story follows Sachio as he navigates this dangerous attraction, terrified of being devoured yet increasingly drawn to the very fox who could consume him.

The situation escalates one night when Sachio goes into heat at an omega-only bar. Ukano appears to rescue him, but when Sachio's heat shows no signs of ending, the fox offers a solution: sexual intercourse, which can end a heat immediately. Despite his terror, Sachio agrees, leading to a physical relationship that blurs the lines between editor and author, predator and prey. As they grow closer, the narrative explores whether genuine love can exist when one partner's instincts scream to consume the other.

The series delves into a richly constructed world where laws regulate animalistic urges, omega-only spaces provide safety, and citizens must navigate constant biological danger. A notable narrative arc involves Sachio's painful reunion with Tomo, a wolf alpha and former college friend who once betrayed his trust. This confrontation forces Sachio to confront past trauma and the societal pressures that blamed him for his own near-devouring. Ukano acts as a mediator, embodying the ideal of an alpha who takes responsibility for his instincts rather than surrendering to them, directly contrasting with Tomo's cowardice. Throughout their journey, from dangerous misunderstandings to tender moments of fur-grooming, the central conflict remains whether Sachio can overcome his fear of being eaten to fully trust the fox who loves him.
