In a dimly lit secret chamber, Chu Zhi discovered, in an erotic painting, the secret of her husband's mistress.
Then she found out that the child she'd raised with such hardship for four years had long ago been switched by her scoundrel husband for his mistress's son!
Desperate, Chu Zhi wondered where her two biological children were. Were they still alive?
To find out what had happened to them, Chu Zhi secretly searched for the midwife from back then, the artist who painted the erotic picture, and the whereabouts of the mistress's daughter...
But in the end, she discovered that everyone involved had either died or gone mad, and the trail had gone cold.
The only way to find out where her children were was to get the truth from her scoundrel husband.

Later, Chu Zhi welcomed the mistress into the household, making her a concubine and putting the two boys born to her at risk of losing their status as legitimate eldest sons.
She used this to threaten her scoundrel husband into telling the truth, or she would ruin his reputation!
But he retaliated by using the children's whereabouts to threaten her into keeping quiet and restoring the eldest son's status.
Chu Zhi nodded in agreement and heard him say, "The children aren't mine. After I threw them outside their biological father's door..."
She trembled all over as she demanded, "Who was the man that night?!"
Her scoundrel husband only sneered. "Chu Zhi, you can't afford to provoke this man."

Four years earlier, at a prince's residence, Xie Wang gripped the fragrant handkerchief in his hand, fury simmering in his dark eyes.
"Turn the whole capital upside down if you have to. Find her for me!"

Before their divorce, Chu Zhi was once again sold by her scoundrel husband to a high-ranking official in exchange for favor. At the critical moment, Xie Wang intercepted her and coldly thrust two children into her arms.
Chu Zhi: "Your Highness, please don't kill me. I can take care of children..."
Xie Wang: "They're the children you left behind!"
