The story of a fallen heiress's struggle. Pei Daining, the daughter of a noble family, lived freely and indulged her whims in her youth. Then, in a single night, her father lost his title and her family fell into ruin. To make matters worse, the First Scholar of Chang'an broke off her long-arranged engagement and married her sworn sister instead. Pei Daining nearly spat blood. She became a laughingstock across the city and couldn't even find a decent family to marry into. Unwilling to drag down her childhood friend Chen Puchu, she had no choice but to save herself. Taking her cousin Sun Xuerong with her, she embarked on a career in business. She was deceived and swindled, but with the help of friends like Li Minzi, she stumbled along and eventually found some success, as well as love. Then, on an impulse, she married the capital's most notorious libertine, just as she was about to lose her way of making money. But Li Ningyu had a side no one knew about. Not only did she help Pei Daining take down the scoundrel, she also let her run wild in the business world. Pei Daining takes on her mother-in-law, her sister-in-law, and even a princess, ultimately rising to the top.
