Sylvia, a chaebol heiress with a rare heat that requires beast-kin companionship, is abandoned by fox boyfriend Felix, who tends to her cousin instead. Seeing his selfishness, she dumps him and chooses Seth, a devoted snake-kin, buying his freedom. Felix assumes she's bluffing—until she signs Seth's contract, realizing he's replaced. He kidnaps her, expecting her to beg, unaware she's already cured and free of him forever.
