Maybe I’m a little late on this, but I actually got their twitter handle a looong time ago before they decided to delete their twitter account. Unfortunately after hours of trying to find them when I was in your position, it really does seem like it. Coincidentally, they also began drawing/writing a recent BL in a new company, so I assume they must have been forced to due to policies? I’m really not sure. But I do have one screenshot of a simple character bio of the characters as proof. :<

I tried going around and learning who this author is but there is zero information about them out there. Nothing, nada. No social media handles, blogs or websites. Not even a Linkedin. They're completely shrouded in mystery. I know a lot of creators prefer being anonymous but looking at the nature of their work, which will remain their magnum opus for ages to come regardless of what they write next, if ever they do - it's giving that they were either themselves a resident or traveller to Kowloon or they really thoroughly read the book City of Darkness Revisited so well the knowledge manifested itself on paper and ink in story form through the author's hands. I feel like I'm doing detective work chasing dead ends even though I'm just an obsessive bookwork haha. I mean damn author-nim you just dropped an underrated masterpiece and vanished into the fog - no afterword or creator's note or anything, like some disembodied narrator. Mad respect for that buzzfeed unsolved image, but seriously: who are you?
