After a father turns into a serpent monster and dies, she’s taken into a noble household—paraded like a pampered lady but used as a scapegoat to “absorb” the family’s misfortune. Only a fellow servant in the same plight gives her room to breathe. As life grows more brutal, she discovers the heirloom she swallowed is actually that man’s Reverse Scale—a taboo core that binds fate, rage, and desire. Determined to free him and escape this house of curses, she’s pulled into a dark, adult web of power plays and forbidden intimacy—where one wrong touch can awaken the beast.
