The married, celibate Crown Prince of Great Zhou × a commoner who becomes a princess through marriage to the Western Regions × a knight turned domineering, calculating minister of the Western Regions
She was a princess of the Western Regions, but after an accident, she became an orphan in Great Zhou and was adopted by Bai Heyuan on Mao'er Mountain.
During an outing, she took in another orphan, Xu Qiyue, as her younger sister. She also met Ning Weiyou, the Crown Prince of Great Zhou, who was destined to be the love of her life. He was unmarried then, but by a twist of fate, the two missed their chance.
On his wedding day, he took Qin Nanyi, the third daughter of the Chancellor, as his Crown Princess. At the time, he still did not know who she really was...
After the imperial edict was stolen and a sword pierced her heart, her beloved senior brother treated her wounds and saved her. They fell for each other, but neither had the courage to unravel the tangled relationship between them.
In the end, he left and became an adviser to the Western Regions, making an enemy for life of Ning Weiyou, the Crown Prince of Great Zhou. They clashed for years.
In the end, he was the one who failed her, while the other man never married.
