In a society where humans can buy and bond with genetically engineered werebeasts, Y/N, a low-tier human, purchases Carden, a high-grade werefox who once begged her to save him when he was considered defective. At first, he is grateful, but after experiencing humiliation from society and growing close to a wealthy human named Cecelia, he becomes cold, arrogant, and increasingly cruel toward Y/N. Carden begins insulting Y/N’s status and dismissing her care, while Cecelia’s presence reinforces his belief that he deserves a higher-class life. Despite this, Y/N endures his emotional neglect and mistreatment for a long time. Eventually, she realizes the bond has become toxic and one-sided. Y/N secretly arranges a transfer through the Werebeast Exchange and chooses a gentle, unwanted werewolf to save from being sent to a deadly arena. As she prepares for a new beginning, she tells Carden she is transferring ownership, ending their bond and reclaiming her freedom.
