The protagonist, eldest daughter of the prestigious Cui family of Qinghe in the Great Zhou Dynasty, and younger sister of the Crown Princess. Known as the most beautiful woman in Luoyang, she is stunning and graceful yet described by outsiders as arrogant, domineering, and overbearing. In reality, she is a little spoiled and headstrong but easy to coax. She has been frail since birth, weighing less than three pounds, with pale skin white as snow and radiant features like a peony in full bloom. She married her childhood sweetheart Pei Yu ten years ago after he promised to love her for life and never take a concubine. When she discovers Pei Yu's affair with a Yangzhou courtesan, she demands divorce, only to learn her entire Cui family has been executed for alleged treason.
