The human princess, Catherine, witnessed the fall of her homeland at the hands of the dragon king, Victor. Her father perished tragically, and she was reduced to an orc slave. Driven solely by the desire for vengeance, she set her sights on obtaining the Heart of the Sun to assassinate the dragon king. At their first encounter, Victor was captivated by Catherine's defiance and decided to keep her by his side. Meanwhile, Helen, a female general infatuated with Victor, repeatedly framed and persecuted Catherine, attempting to end her life on multiple occasions.
Catherine managed to turn the tables on a cruel overseer in the mine. During a banquet, when she was humiliated, Victor intervened forcefully to protect her. To ensure her own safety, Catherine falsely claimed to be pregnant, but Victor saw through her ruse from the start and merely used it as an excuse to keep her close. Helen set fire to the place in an attempt to burn Catherine alive. Undeterred by the dragon - fire that could subdue his kind, Victor transformed into a dragon and rushed into the inferno, rescuing Catherine at the cost of severe injuries. In the courtroom, Catherine skillfully utilized a sacred iron box to expose Helen's crimes, leading to Helen's exile to the desolate wasteland.
