Seven years ago, human girl Cecilia made a cruel deal with a black witch to save the dying Alpha heir Lucian, sacrificing all her memories, while her mortal body was branded with a fatal curse mark from the backlash of the dark magic circle. Seven years later, the amnesiac Cecilia struggles to survive at the bottom of a remote border town with her daughter Amaya, who is born with top-tier werewolf bloodline. To save her seriously ill mother, Amaya sets out on a journey to find the werewolf tribe's sacred treasure, the "Moonstone," but repeatedly clashes with Lucian—cold, violent, and relying on medication for seven years to forcibly suppress his wolf's manic nature. When the bond of bloodline can no longer be hidden, Lucian finally discovers that the Mate he has desperately searched for over seven years is right before his eyes. Facing the brutal persecution of pure-blood nobles and an insurmountable class chasm, Lucian transforms into a wife-protecting maniac, while Cecilia awakens the sleeping white witch bloodline within her in desperate circumstances, tearing apart the scheming villains and reclaiming her Luna glory!
