I think it's a yaoi manhua or a manhwa but it was full colored. It's about a fantasy world where the seme is a fox-demon? but is also human (he has black hair) and the uke is a human. The uke attended this school that is unknown to the public as a school for these demons? (i forgot the term i just used demons) and the seme gave one of his hearts to the uke so that he could live.
Any Yaoi that has like a depressed Seme and the Uke comforts him, and throughout the story thei character development improves
though uke also has some issues

hello. i’ve been reading isekai/reincarnation/transmigration historical shoujo/shounen ai manhwas lately and i’ve notice a pattern where the MC usually has background knowledge or knows the whole story which makes their character seem trite because of how predetermined everything is. With that context in mind, does anyone know of any works, preferably mystery, where the MC is oblivious to everything; the plot could be about anything, thank you.
