I recommend 'The Wind, the Flowers, the Falling Snow, and the Moon' to you. It's a novel about Xianxia and Wuxia romance. The female lead's smile was dazzling, like warm sunlight, emitting light from her entire body. The male protagonist was the Demon Lord of hell. He could only live in endless darkness and could never see the light. I hope you like this fairy's recommendation. Muah ~😗
