My Father's Killer Is My Master

DramaBox synopsis

Hunter heiress Scarlett's family is slaughtered. Vampire lord Cassius claims her as his own, but she plots escape. Kidnapped and nearly sold, Cassius rescues her, cutting ties with his kind. The elder's conspiracy emerges: Cassius spared her not for slaughter but for her blood's power. Forced to fight together, they forge a blood bond. They defeat enemies, end the hunter-vampire war, and marry—from enemies to partners.
