Seven years ago, medical researcher Selena accidentally entered a hotel room and saved Lucas—a vampire prince and CEO of Morgan Group—from his Blood Thirst with her sweet blood. After one night together, she fled. Seven years later, her daughter Amy is hospitalized with a rare genetic disease and is revealed to be Lucas's biological child. Diana, who claims to be Lucas's destined wife, forces Selena into Morgan Group's underground lab to develop a blood stabilizer, using Amy's treatment as leverage, while a dark witch seals Selena's true scent. Amid workplace persecution, Amy sneaks into Morgan headquarters and shares an uncanny father-daughter bond with Lucas. When Diana turns murderous, Amy awakens her pure-blood vampire powers to protect her mother. Lucas finally discovers she is his daughter, and the family's fated bond is revealed.
