The Yongchang Marquis's Concubine-Born Wife by Proxy

Xie Qingyu, a concubine-born daughter of the Xie family, has always been cautious and meek. Everyone thinks she's an easy target they can push around.

Only she knows that her mild, timid nature is merely a disguise to keep others from seeing through her.

Xiao Jinghuan, Marquis of Yongchang, has rendered such great service that he threatens the throne. To avoid arousing the emperor's suspicions, he decides to marry a daughter of the Xie family.

Everyone envies the Xie family's legitimate daughter for landing such a fine match, but Xie Qingyu secretly plots to switch the marriage and take her sister's place in the marquis's household.

From now on, she will no longer be the lowly concubine-born daughter of the Xie family, dependent on others and forever meek.

She will become the honored and cherished Marchioness of Yongchang, master of her own fate and heir to the riches she deserves.
