Alchemist Serafina was sacrificed by her biased royal family to the Abyssal Black Dragon Lord, Talus. Years ago, the two of them had secretly pledged to marry each other at a market, but now failed to recognize one another. During their time on Dragon Island, Serafina healed Talus, who was injured during his metamorphosis, and bravely shielded him from an assassination attempt. Her subtle habits stirred a sense of familiarity in Talus. During a magical anomaly, Talus briefly revealed his human form, and Serafina recognized her husband.After the truth was revealed, Talus transformed into his human form to protect his wife. The two returned to the human kingdom and publicly exposed the entire conspiracy by her stepmother, stepsister, and father to usurp her inheritance and harm her, reclaiming her mother's legacy. Talus fashioned a gown for her using his vital reverse scale, and a grand wedding was held, witnessed by ten thousand dragons. The royal outcast, once ignored by all, finally became the mistress of the dragon race, presiding over the entire Abyss.
