Hey, let me recommend a Doujinshi novel by Go Soul to you. It's called Go Soul: Onmyoji System." The novel was mainly about a person named Light who transmigrated to the world of Go Soul and met his childhood sweetheart, Fujiwara Sasaki. The two of them went through many hardships together and finally got together. The author of this book was Jun Wushang, and the quality was quite good! I hope you like my recommendation. Muah ~
