After her husband left and sold Shanjue and Qianhui, the mother continued prostituting herself.
The only difference was that she had three fewer burdens.
She thought to herself, why didn't she do this earlier? Life would have been so much easier, and she could have taken many more clients. Besides, she never thought much of her husband's money anyway.
She already had a backup—a man who could truly satisfy her. The key point was that this man was a sugar daddy, which in her eyes was ideal.
She also thought it was very clever to sell off her two remaining children, especially since she wasn't even sure who their real father was.
