After Shen Zhiyi, who grew up in the countryside, learns that she is the real daughter of the Earl of Changshun's family, the only thing she sets her sights on is the marriage tie with the Xu family, the empress's maternal clan. So she promptly claims her birth family and seizes the marriage for herself.
The Shen family survived a case that should have wiped them out only because, after saving the Xu family's matriarch, they arranged a marriage between her and the Xu family's eldest son. Now that the real daughter has returned, the two families disagree over who should receive the marriage tie that will decide the Shen family's fortunes.
Xu Fengmian took charge of his household at fourteen. Handsome and exceptional, he was among the finest young noblemen in the capital. He valued Shen Zhiyi's thoughtfulness, gentleness, and pliable nature, and so he married her.
Each of them thought that, if only they were patient and gentle with each other, they could surely live together in harmony.
Until one day, he discovers she is the adopted younger sister his political rival cares about most.
And she discovers he has a chivalrous first love he could never win.
(First married, then fall in love. The heroine admires her adoptive older brother; the male lead's first love is the heroine.)
