The first 4 parts has fan translation in Ao3 (or at least it was still there week ago) but the translation is bad, it is almost unreadable not because the translation would be inaccurate (which it also is at times) but because it almost looks like it was translated sentence by sentence by someone who has no clue about English grammar and sentence structure.
But it was just announced that this will get official translation by Mullebooks. It should come out at the end of this year so I would wait until then. You can read the novel in Korean in Ridibooks. I think reading it in Korean and using AI translation will get you better results than what the fan translation in Ao3 offers.
Guys, despite what Rain said I still think its worth a shot to try the fan translated english novel. Its not perfect but its still readable. Trust me, I've seen worse than that. And if you really dont feel like waiting its a nice way to start the novel until the official translation comes out. Not trying to hate, just putting my feelings on all of this
Where can you find the novel?
