In a world where humans and dragons coexist, Claudia, the daughter of the noble Charon family, refuses the Dragon King's marriage proposal and insists on marrying Ben, a human. To test their love, her father seals her dragon powers, promising to acknowledge their relationship if they remain unchanged for three years. Three years later, pregnant and full of hope, Claudia receives a video of her husband's affair with Raven, suffering a devastating betrayal. During a confrontation, she is hit by a car and rescued by a mysterious man in a suit, Maxim, unaware that he is the cursed Dragon King seeking a female dragon to prolong his life. Raven is not only the other woman but also impersonates Charon's daughter to deceive Ben. Claudia suffers repeated humiliation in the hospital and at home, even being kidnapped and tortured by Raven. On the verge of death, she is rescued by her father and Maxim. After the seal is broken, she transforms into a giant dragon but collapses due to exhaustion. After miscarrying her child, Claudia awakens her dragon powers and, with Maxim's help, returns as the true heiress. She uses business and social means to take revenge on Ben and Raven, ultimately making them pay a heavy price. She also stays with Maxim, beginning a new legend.
