I recommend "The Reborn Daughter Becomes a Concubine", an ancient romance novel. The protagonist, An Shi, was betrayed by her husband in her previous life. After her rebirth, she vowed to repay all those who betrayed her and change her life at the same time. She used her intelligence to help her husband become the emperor, and at the same time, she took revenge on the enemies of her previous life. I hope you like my recommendation. Muah ~
