There were a few novels that were similar to the love story of King Yama. Among them were Yama's Spoiling: The Story of Meng Po Chasing Her Husband and Love in Hell. These novels belonged to the category of classical Xianxia and fantasy romance, describing the love story between the heroine and the King of Hell. Other than that, there were also some other novels that were recommended, such as " A Warm Marriage in a Prosperous Age,"" The Little Daughter of the King of Hell,"" The King of Hell's Mercy," and so on. I hope these recommendations will meet your needs.
