honestly I don't understand why this is so highly rated. I tried reading the novel but I the author's writing style turned me off, so I tried reading the manga, and after 5 years of following the manga, I can say with confidence that the series fucking suck to me, especially since I don't relate to or like any of the character.
It seems like the author tries to develop deep character with complicated personality and problems, but all of that just feel flat and utterly nonsense/whimsical/dumb to me.
(I've read many things over the years, and I can say with confidence that there are many novels/manga better than this. Hell, even the CN manhua/novels are better than this, which say a lot tbh.)
anw, for any new readers who skim the comments to check the story before reading it, my advice to you is: if you don't like/relate to the two MCs within the first 5 chapters, this probably won't be your thing and it's best to skip it.
