Just like the title of the novel, the male protagonist has bad luck every time he takes an exam, and the female protagonist will predict the future that will harm his situation. The male protagonist marries the female protagonist, and the female protagonist dreams about the future, which changes the male protagonist's destiny. To think about it from another perspective, the female protagonist is the golden finger given to the male protagonist by the author. But the writing is good. I read it in one sitting when I didn't think much about it before.
After the heroine Chuang Cheng just got married to her husband, a young general, she tried to save the hero in prison. The two escaped from prison, saved their families, found helpers, fought, and supported them all the way. I feel that in the hero's heart, the heroine is his support.
The female protagonist travels through the book and marries the male protagonist (who is a big villain in the book) who is exiled to the northwest. The female protagonist sets up a stall to earn money to take care of the family, while the male protagonist supports the family with his widowed mother and sister. I have forgotten what happened in the back, but the front is more profound.
The heroine dresses up as a princess and escapes with the hero on the way to exile. The escape is very exciting. The two complement each other and finally return to Kyoto.
