I recommend the modern romance novel," Love in the Willows ". The female protagonist is an orphan, and the male protagonist is a business elite. As his secretary, the female lead helped the male lead relieve his sleep problems, and the two of them gradually developed feelings for each other. However, there was a problem between the two of them, and the female lead eventually left quietly. Three years later, the female protagonist returned to the male protagonist with a pair of twins, but she said that the children were not the male protagonist's. The male lead was furious. I hope you like my recommendation.
