There are a few books that fit this plot. I recommend the following: 1. Beast Taming Cute Treasure: The Black-bellied Princess Run With the Ball. The female protagonist bid farewell to the male protagonist after having a child out of marriage. They met again six years later. The male protagonist rushed to be a father, but the female protagonist thought that the male protagonist was not qualified. 2. "Reborn Little Baker". After the female protagonist transmigrated, she had a child out of marriage. In order to cure her illness and support her family and raise her two sons, she worked hard and finally fell in love with Qiao Yuandong. 3. 'Mother, His Royal Highness Father is here to urge us to get married again.' The female protagonist had a child out of marriage. After her rebirth, she refused to marry and returned to the Bai residence with the child. The male protagonist continued to pursue the female protagonist and received her daughter's approval. I hope you like this fairy's recommendation. Muah ~😗
