Synopsis;
Ning Qingwan learned that she is not the biological daughter of the Ning Marquis's mansion only 3 years ago. All her devotion to the family and hard work to fill the mansion´s millons of deficit were in vain, when she was betrayed by the biological daughter, Ning Qingle, who seduced FL´s fiancé and got pregnant, and her family who discarded her as she wasn´t useful any longer.
Being brutally murdered by her family, FL was reborn with a thirst for revenge. She meticulously planned her revenge, regaining control of the household management before relinquishing it at the opportune moment, plunging the mansion into a financial crisis, exposing Ning Qingle's conspiracy, and making her look foolish. During this time, she met and allied with the Third Prince, Xiao Yan, to investigate the mansion's secrets. Ultimately, Ning Qingwan exposed the mansion's crimes, leading to the exile of its members. She also broke free from the mansion's constraints and finally married Xiao Yan.
