Athanasia de Alger Obelia, the sole legitimate princess of the Obelian Empire, begins experiencing flashes of memories from a past life that reveal a tragic future—her own death at the hands of her father, Emperor Claude. While Claude showers affection on her older sister, Jennette Margarita, he treats Athanasia with cold detachment, making her desperate for his approval. Determined to change this bleak destiny, the infant Athanasia plans to flee the palace once she grows old enough, avoiding her father until then. However, their meeting occurs sooner than anticipated, and Athanasia finds herself exposed to Claude's unpredictable temper. To her surprise, he does not display the indifference she dreaded. Now acknowledged as part of his family, Athanasia works to become a worthy successor to the throne, yet her dark premonition continues to hang over her.
