Vicious Matriarch’s Daily Whitewashing

Gu Wanning transmigrates into the body of a vicious matriarch who has been tormenting her husband's four concubines for three years. Her husband, Xu Weibai, a decorated military marquis, is returning home furious after receiving letters from the concubines claiming abuse. Gu Wanning must survive his wrath while navigating a household in financial ruin due to embezzlement by the steward.

Xu Weibai returns on their wedding day to find his concubines treated brutally—forced to wake at 3:30 AM for manual farm labor under the sun, causing them to age rapidly. He accuses Gu Wanning of jealousy and talkativeness, grounds for divorce, but she refuses to accept being cast out with a tarnished reputation. Instead, she demands an amicable separation while secretly discovering the household's accounts are missing six hundred taels.

The Grand Princess, Xu Weibai's grandmother, insists the couple produce a legitimate heir together and forbids any concubine from bearing children before Gu Wanning. She also arranges a bedding schedule for Xu Weibai to visit each concubine. Meanwhile, Gu Wanning sells poultry and discovers corn seeds, hoping to profit from agriculture. The Second Concubine, a merchant's daughter, reveals the pawnshop is family-owned and offers eight hundred taels to ensure Xu Weibai visits her courtyard.

Gu Wanning realizes she can monetize the schedule, auctioning off Xu Weibai's nights to the highest bidder. She plans to sell her own slots and expand the business externally, turning the Marquis Residence into a profitable enterprise while avoiding intimacy with the man she despises.
