After the female protagonist was reborn, she vowed to take revenge, but she involuntarily fell into the trap of another man. I hope you like this fairy's recommendation. Muah ~π
He recommended the novel " Double the betrothal gift and marry his ex-girlfriend." The plot matched the question. After the male protagonist and the female protagonist got married, the male protagonist's ex-girlfriend came back and misunderstood that the female protagonist had pushed her down the stairs, causing the male protagonist to divorce. But later, the male protagonist proposed to his ex-girlfriend and her ex-girlfriend agreed. They finally got married. Although the plot was a little twisted, it eventually led to a happy ending.

The book," Enchanting Wife's Marriage," might meet your needs. The female lead, Xia Xiao, was exposed to sinister gossip. Later, she married Chu Rui and found out that her originally mighty and domineering husband was actually a soft bun. During the refund incident, she was pressed down by him and asked for a refund, but he refused. The book also included the plot of the female protagonist being pushed down the stairs and causing a miscarriage. I hope you like my recommendation.
In the novel,"Supreme Favor: The Foppish Demon Concubine Concubine," the female protagonist died after the surgery was ineffective. The male protagonist became a spiritual fox. The female protagonist pushed the male protagonist and caused him to receive an electric shock. In the end, the male protagonist doted on the female protagonist. It was an oriental fantasy novel. The plot was varied and interesting, and the interaction between the female and male leads was also very interesting. I hope you like this fairy's recommendation. Muah ~π
I recommend the book "The Female Supporting Character, God's Assist" to you. This novel was about a female supporting character who felt that the female protagonist was better than her in all aspects, but her emotional intelligence was not enough to hang on to the male protagonist. The female supporting character who transmigrated became a stumbling block on the male protagonist's way to pursue his wife. The female protagonist also traveled back to her childhood and started anew, wanting to change her fate. This novel is quite similar to the problem plot you described. I recommend it to you. I hope you like this fairy's recommendation. Muah ~π
"A Guide to Self-Saving Through the Book: The Female Supporting Character's Strategy on the Male Lead's Counterattack" was a book that fit the description of the title. The male protagonist treated the female protagonist very well as a substitute for the female supporting role. Later, when the female supporting role came back, the male protagonist gave the female protagonist to the second male lead. The female lead later fell in love with the second male lead, and the male lead regretted it. I hope you like this fairy's recommendation. Muah ~π
