Yes, I recommend two novels, You Are My Painted Landscape and Three Treasures in One Birth: The CEO's Daddy Has Many Tricks. In "You Are My Scenery," the male and female leads slept with each other. The female lead threw 200 yuan to the male lead and left. Five years later, the male lead chased after the female lead and asked her to return a son. "Three Treasures in One Birth: The CEO's Daddy Has Many Tricks" The female protagonist fled after she became pregnant. She did not expect to give birth to three babies. One of the daughters was even stolen. Five years later, her son returned strongly. The female protagonist realized that the male protagonist was originally not married. After she became pregnant, she wanted to force the female protagonist to go to him and did not want the female protagonist to escape. The two novels were about the male and female protagonists having a relationship before they met and had a child. They met the requirements of the question. I hope you like this fairy's recommendation. Muah ~π
