Ayla Winter, the eldest princess of the Kingdom of Winter, is poisoned and thrown into the sea by her younger sister Leah and her fiancé Eric on the eve of her coronation.
She miraculously survives and is rescued by a shepherd girl named Sophia. After suffering a severe head injury, Ayla loses her memories and her mind regresses to that of a five-year-old child. Sophia names her Angel, accepts her as her mother, and begs her disabled duke father, Ron Marlborough, to marry her.
After witnessing Angel’s extraordinary strength, Ron chooses to marry this woman whom everyone believes to be foolish and insane, in order to protect his family.
With her memories lost, Ayla instinctively protects Sophia. In moments of crisis, her royal ice magic awakens. She pretends to remain childish and foolish to deceive her enemies, while secretly gathering her loyal followers and preparing to reclaim her throne during Leah’s coronation.
The cold and distant Ron has already discovered her true identity and silently protects her from the shadows.
As the coronation approaches, Leah summons dark mages to eliminate her rivals. At the grand ceremony, Ayla finally removes her disguise. Wearing the royal gown and riding an ice dragon, she stands proudly atop the Ice Tower.
A devastating blizzard engulfs the royal city. The rightful queen has returned, and the final battle to punish the betrayal begins at the coronation banquet.
