A Swap of Brides into a Marquis’s Household: Two Sisters, One Scheme

On the eve of their weddings, the Shen sisters uncover a decade-old military grain scandal hidden in an unfinished piece of embroidery left by their late mother. The accounts are concealed in the northern granary of the Marquis of Dingbei’s residence, while a witness is trapped in the western courtyard of the Marquis of Jing’an’s residence. Their father deliberately sends the elder daughter, Shen Zhiwei, who is skilled with accounts, to marry into the Marquis of Jing’an’s residence, and the younger daughter, Shen Mingtang, who excels at tracking, into the Marquis of Dingbei’s household.

The weddings can’t be called off, so they’ll switch bridal sedans!

A proper young lady marries Pei Yanci, the cold-faced marquis rumored to bring death to his wives, while a frontier warrior finds herself paired with Xiao Chengyi, the capital’s most notorious playboy heir. Everyone expects a spectacle, but the sisters turn the tables: one manipulates the accounts to set a trap, while the other takes up her blade to hunt down the culprit. Together, they tear through the layers of darkness surrounding both marquis households. They also gradually discover that the cold-faced marquis is willing to hand his wife both his power and her way out, while behind the playboy heir’s smiling face lies an intelligence network that has saved countless lives.

A missing wedding-gift ledger, eight thousand dan of vanished military grain, and a “dead man” imprisoned on an imperial estate eventually lead them deep into the palace.

The sisters don’t turn on each other, and the couples solve the mystery together. The bridal sedans were switched, but they married exactly the right people. They will avenge their mother, win justice for the wrongly slain, and drag the mastermind behind the phoenix crest from his lofty position with their own hands, while carving out a future where they can hold their heads high.
