The Fertile Female is Incredibly Sweet and Soft; The Sterile Beastman Pulls Her in for a Kiss

Lu Xia, a researcher who survived the apocalypse, transmigrates into the body of Duke Lu Xia in a world where females hold absolute dominance and males are subservient beast-humans. The original host was infamous for her cruelty and lecherous nature, yet physically weak due to a heart condition. Lu Xia awakens to find herself in the bed of Grace, a male beastman with a gene fusion rate below thirty percent, labeled a defective product. Grace is the eldest son of the Leslie Duke family, sent to Lu Xia as a Husband-Attendant because of his low status. Despite his humble position, Grace is a colonel in the Empire’s First Military District, a rank he achieved through immense personal struggle against systemic discrimination.

Lu Xia refuses to indulge in the original host’s abusive habits. Instead, she establishes a submission contract with Grace, not to torment him, but to secure a loyal ally in a hostile world. She allows him to retain his military career, a decision that shocks the military district, where males are typically forbidden from working outside the home. Lu Xia also takes charge of the family’s failing pharmaceutical research institutes. Using her knowledge from the apocalypse, she plans to revitalize the companies by developing advanced beauty and health products, such as scar removal creams and hair regrowth solutions, aiming to create a profitable enterprise that will secure her financial independence.

The narrative takes a dramatic turn when Lu Xia’s terminal begins flashing a green light, indicating pregnancy. In this era, natural conception has been impossible for centuries, as reproduction relies entirely on technology. The Empire’s Reproduction Research Institute detects the signal and launches a search for the source, viewing it as a potential breakthrough for human evolution. Lu Xia, initially in disbelief, confirms her pregnancy through a private medical examination. She learns that Grace, despite being classified as a defective product, is actually capable of natural reproduction, a fact that contradicts all known biological data in this world.

As Lu Xia navigates her new reality as a pregnant duke, she faces increasing scrutiny from both the military and the research institute. At the First Military District, Grace faces hostility from colleagues who resent his promotion and his continued service. Colonel Kofi challenges Grace to a duel, questioning his worth as a defective product. Lu Xia arrives unexpectedly to support Grace, publicly claiming him as hers and challenging Kofi to a duel with high stakes. Her intervention shifts the perception of Grace’s status, elevating him from a mere Husband-Attendant to a figure of respect within the military hierarchy.

Lu Xia’s actions begin to dismantle the rigid social structures of the Female-Supreme world. By treating Grace with dignity and allowing him autonomy, she disrupts the expected power dynamics. Her focus on rebuilding the family’s research institute also positions her as a serious businesswoman rather than the frivolous duke rumors describe. The story follows her efforts to balance her growing responsibilities as a business owner, a pregnant woman in a society unprepared for natural conception, and a partner to a man who is slowly learning to trust her. The impending attention from the Reproduction Research Institute looms as a significant threat, forcing Lu Xia to protect her secret while establishing her authority in a world that underestimates her.
