The Dragon King's Secret Daughter

Four years ago, human Elena jumped into the abyss to protect Dragon Emperor Balthazar's Heartscale. She raised their daughter Aria to age three before dying. Braving snow and wind, little Aria travels alone to the dragon castle to return the precious scale. Though consumed by misunderstanding and rage, Balthazar is gradually softened by the girl's pure affection. Power-hungry noble Seraphina plots against Aria and stages a rebellion with the Elder. At the critical moment, a memory stone hidden in Aria's doll exposes the truth of Elena's death. Enraged, Balthazar breaks the magic seal, crushes the rebellion and punishes the traitors. At the baptism, Aria—once dismissed as a worthless half-blood—awakens the legendary Pure-Blood Dragon-God power. After countless hardships, the tyrant turns into a devoted father. Healed young Leo swears lifelong allegiance to Aria, and the found-family embraces a peaceful new life.
