Baoyu City in the Huan Kingdom is wealthy and captivating, a bustling city famed for its abundant white jade.
The Bai clan, led by its city lord, Bai Senchi, appears splendid on the outside, but decaying values and extravagant habits are eating away at the family.
Five years ago, the Bai family's enemy set fire to their home. Bai Senchi's wife and three children perished in the flames. Bai Senchi was spared because he was away from the city, but he lost his son, whom he considered his only heir.
The only one left was his eldest daughter, Bai Bingying, who was shunned by the family.
He forced his daughter to live as her deceased younger brother, Bai Ying, because she looked so much like him. Living under Bai Ying's identity, Bai Bingying left Baoyu City with her uncle, Bai Cheng. They went not only to lie low, but also to undergo five years of grueling training.
Five years later, at seventeen, she has grown into a "beautiful young man" who makes countless girls swoon. Yet beneath tremendous pressure, her hatred for the family has not faded in the slightest.
The arrival of that girl, Zhang Yuan, may bring a splash of new color to her monotonous life.
