After marrying Zhou Yuan Shen, she learned that he had a concubine with a powerful background and had an affair with his widowed sister-in-law. She hated the rigidity and dullness of noble ladies.

Since she was married as a mistress, she would clean up the mess for the Duke. When my position is stable and I have children, you will be the next mess to be cleaned up!
