Yun Yang transmigrates into the body of a female in the Federation, a society with a severe gender imbalance where males outnumber females by one hundred thousand to one. In this world, males can transform into beasts and possess superpowers, but using these abilities generates pollution that can lead to loss of control. Females, though physically weaker, possess spiritual energy capable of purifying this pollution. The original owner of Yun Yang's body was engaged to Wei Zhuo, a male who consistently rejected her and demanded the engagement be annulled, believing she hindered his pursuit of true love. Upon waking, Yun Yang immediately agrees to the annulment, surprising Wei Zhuo, who had expected her to plead otherwise. The Federal Marriage Center swiftly processes the dissolution, and Yun Yang, now single, decides to utilize the Federation's polyandrous marriage system to find suitable beast husbands.
Yun Yang submits her matching information to the Federal Marriage Center and is surprised to learn she has an S-rank mental strength, a rarity that places her among only three such individuals in Federation history. This revelation triggers an influx of match requests from males across the galaxy. The Marriage Center selects five high-quality males with S-rank superpowers and high genetic compatibility for her. Among them is Qin Mo, a Deputy Commander in the Federation Army with a white tiger beast form and an S-rank metal ability. Qin Mo arrives at Yun Yang's villa, initially appearing nervous and gentle, but reveals a fierce, protective side when Wei Zhuo reappears to regret his decision and attempt to reconcile. Qin Mo physically assaults Wei Zhuo and reports him to the authorities for disturbing a female, establishing his dominance and loyalty to Yun Yang.
As Yun Yang adjusts to her new life, she discovers she possesses a latent, unknown F-rank superpower alongside her S-rank mental strength. During a test with Qin Mo and another matched husband, Xuan Yu, an S-rank ice ability user with a frost wolf beast form, Yun Yang realizes her power functions as an enhancement or blessing, temporarily boosting the abilities of other superpower users. This discovery marks a significant turning point, as it suggests Yun Yang holds unique value beyond her mental strength. The narrative follows Yun Yang as she navigates relationships with her five beast husbands, manages the political and social dynamics of the Federation, and uncovers the true nature of her abilities while dealing with the aftermath of her broken engagement and the sudden shift in her status from an overlooked fiancée to a highly sought-after S-rank female.
