There were two novels with the main characters named Leng Xin. They were "Leng Xin Charming the World" and "Exclusive Marriage: CEO Please Get Out." "Cold Heart Charming the World" was an ancient romance novel. The main character, Leng Xin, was a demon emperor. After being plotted against by a servant girl, she traveled to ancient times and was blossomed with peach blossoms. "Exclusive Marriage: CEO Please Get Out" was a modern romance novel about wealthy families. Leng Xin was the male protagonist's name, and there was a substitute plot between him and the female protagonist. I hope you like this fairy's recommendation. Muah ~😗
