I recommend " Good Morning, Young Master Qin." In this modern romance novel, the male protagonist, Young Master Qin, fell in love with the female protagonist at first sight. The female protagonist was always by his side, but he did not realize his feelings. It was not until the female protagonist suddenly left that the male protagonist realized that he could no longer leave the female protagonist and began to track down the female protagonist. In the end, the two of them got together and lived a happy life. I hope you like my recommendation.
