I recommend the following two novels to you: 1. In "The Fox Lord's Demon Slayer is Beautiful and Savage," the female lead, Mu Zilin, was a Demon Slayer, while the male lead, Fox Thirteen, was a nine-tailed demon fox. After the two of them got together, the male lead was extremely beautiful, but he also doted on the female lead. However, the mystery of the male protagonist's background and the obstacles from the outside world made this relationship full of twists and turns and pain. It could be said that it was a torture to the male protagonist's heart. 2. In "Bewitching Concubine: The Gorgeous Demon Slayer", the female protagonist was a demon slayer, while the male protagonist, Nine Hall His Highness, was a cold and heartless person. However, under the treatment and attention of the female protagonist, he was gradually moved and melted. However, the mystery of the male protagonist's background and the obstacles from the outside world made this relationship full of twists and turns and pain. It was also a plot that tortured the male protagonist's heart. I hope you like my recommendation. Muah ~
