Gu Xiuniang's sister-in-law, following Gu Xiuniang's instructions, secretly swapped the newly born baby girl with one from another family.
The mother-in-law seized the opportunity and switched the Marchioness's son for Gu Xiuniang.
And this son was naturally the male lead.
Thus, Gu Xiuniang became the foster mother of the male lead.
However, Gu Xiuniang herself was unaware of this arrangement. Satisfied with her own achievements, she raised the male lead as if he were her own cherished son.
Meanwhile, Gu Xiuniang's daughter became the "Fake Lady" of the Marquis Mansion.
However, it wasn't many years before disaster struck the Marquis Mansion, leading to its downfall and auction.
Though Gu Xiuniang's mother-in-law served in the Marquis Mansion, her husband was a decent citizen and, under the protection of the Marquis Mansion, had a modest estate.
After the fall of the Marquis Mansion, Gu Xiuniang's husband quickly redeemed his old mother.
