Luo Mingzhu, the legitimate daughter of the Marquis of Yong'an, appears to be unpopular and her marriage is being manipulated, but in fact, she secretly runs Dayan's largest business, "Wan Zhen Lou", and is the richest man in the capital.
In the beginning, Luo Mingzhu was drunk and framed by her fiancé, Prince Xiao Chengyu of Anping County, and her concubine, Luo Yunrou. She was originally going to be sent to the dandy's camp to destroy her innocence, but she mistakenly broke into the camp of the regent Huo Yuan and entangled with him all night.
After she woke up, she dropped the jade pendant and ran away, preparing to refuse to admit her guilt, but Huo Yuan came to propose marriage with the jade pendant in hand, causing an uproar in the capital.
After marriage, she appeared dignified and well-behaved, but in her mind she was planning to take away the dowry, save the business, and run away every day. Huo Yuan, who suffered a head injury in his early years, could hear her voice alone. So he started to push the limits of "she thought she had deceived the whole world, and he had already listened to her heart", and from then on, he pretended to be cold while protecting her shortcomings.
