In the hidden storyline, it was revealed that the original Jiang Lai and the female protagonist Jiang Yu were deliberately swapped in identity.
Eighteen years ago, Madam and the concubine were pregnant simultaneously and gave birth on the same day. On that ancestral worship day, the entire Marquis Mansion stayed in the temple because the temple abbot said that it would be best for the double joy of the Marquis Mansion to give birth in the Bodhisattva Temple.
Thus, that night, a fierce wind blew out all the candles in the temple. After giving birth, the energetic concubine secretly switched her own child with the daughter of the fainted Madam.
When the candles were reignited, the concubine was holding the crying baby, her eyes filled with tears.
From then on, the true daughter of the Marquis Mansion, Jiang Lai, was raised by the concubine, while the concubine's daughter was pampered and cherished by Madam.
