I recommend "Love with the Two-Faced General" to you. This ancient romance novel has a plot where the female protagonist has been married for three years without having a child, and there is also a plot where she marries the Crown Prince after being divorced. Moreover, the female protagonist had forged a marriage agreement as a delaying tactic. In addition, the novel also had various fights such as house fights and palace fights. The female protagonist finally became the princess of a weak country and became the winner of the house fights and palace fights in a domineering manner. I hope you like this fairy's recommendation.
