Qi Yue is a doctor. She accidentally crossed into ancient times and became a young lady of Dingxi Houfu, that is, Qi Yueniang, the wife of the Prince of Dingxi Houfu (the wife of the man). The man didn't like Qi Yueniang at first, but after the woman crossed over, the two fell in love in a quarrel, and the people in Dingxi Houfu also changed from disdain to love when they got along with her. But the man's stepmother (his sister-in-law) refused to accept the woman and asked the man to remarry. The man thought that maybe if he married someone else, his stepmother would not be so targeted at the woman, so he agreed. The hostess was very disappointed when she learned that. In the end, the two separated. Later, the woman devoted herself to the development of her career (saving lives through medical treatment), and later became more and more famous. A lot has happened during this period. The woman forgave the man, and finally, all's well that ends well.
