Elaine, an Omega of the Rabbit Clan, is framed and exposed to aphrodisiac mist, then temporarily marked publicly by Kaiel, an Alpha Marquis of the Black Wolf Clan. The pair with vastly different social statuses grow increasingly entangled through incidents including spa compatibility adjustments, Kaiel rescuing Elaine, and slaying Hawkes in a cave. Elaine awakens from a lowly servant and intimidates everyone by leveraging the duke’s mark. Flynn, Kaiel’s illegitimate younger brother, and Cecilia from the Snake Clan covet the title and repeatedly plot against them. In the end, Kaiel exposes the conspiracy via blood identification, completes the permanent mark with Elaine on the full moon night, and their three-hundred-year blood oath is fulfilled.
