Always leave work on the dot and never stay late for overtime, because the beloved Kyōko-san is waiting at home. That is the unwavering rule the protagonist lives by. His devotion borders on obsession: he loves her with an intensity that verges on trembling, and he would do anything she asks. Kyōko-san, however, hides secrets he does not yet know. What begins as a seemingly sweet, if overly ardent, domestic romance quickly takes a darker turn when Kyōko-san makes a request that shatters his perfect little world.

The protagonist is an ordinary office worker whose entire life revolves around returning to Kyōko-san as quickly as possible. Kyōko-san appears gentle and affectionate, but her true nature gradually surfaces through the wishes she expresses. The first of these requests is to bring her a young boy or girl to be a sacrificial offering. He manages to obtain one victim somehow, but when Kyōko-san asks for more, he finds himself unable to find additional children. Panic sets in: if he fails, Kyōko-san might lose interest in him. Just as his desperation peaks, a mysterious man appears, offering to make him happy. The encounter propels the story into an unpredictable spiral where the meaning of love itself is questioned.

The manga unfolds as a comedic love story, but one that is deliberately twisted. The protagonist’s eyes often look unsettlingly manic, and his monologues reveal a mind warped by excessive adoration. Kyōko-san’s own secrets—what she truly is and why she demands such offerings—remain a central mystery. The narrative mixes dark humor, romantic devotion, and horror-tinged absurdity, all while exploring the lengths one person will go to preserve an idealized relationship. As the plot advances, the line between love and madness blurs, and the protagonist must confront the horrifying consequences of his unconditional devotion.
