Taylor, once an abandoned child in the slums, was actually the youngest of the esteemed Canontus family, the greatest ducal house in the empire. However, a new youngest sister, 'Melia,' had already been adopted into the Canontus family, filling Taylor's place. Can Taylor escape the anger and malice of her sister and return as the beloved youngest child?

Ducal Family
Edgar Canontus: Male. The Duke of Canontus. Taylor's father. He is strict with everyone, but tries to make up for lost love only to Taylor.
Ivan Canontus: Male. The eldest son who will inherit the family. There is a large age gap between him and Taylor, and he cherished Taylor very much until her disappearance.
Raven Canontus: Male. The second son, excellent in martial arts but a reckless one. One year apart from Taylor. Before her disappearance, they were a typical bickering sibling duo, but Taylor's disappearance weighed heavily on his heart.

Marquis Family
Theodore Millert: Male. Middle-aged. The Marquis of the Millert family. Maintains a seemingly good relationship with the Canontus family on the surface, but in reality...?
