sorry but, following this. ( ̄∇ ̄") btw, i felt the same way with smells like green spirit. ╥﹏╥ hands down. one of my fave shounen ai ever. i recommend it every time i get a chance. i'll check my list for you! i'm pretty sure i've read something similar to what you're looking for. i just have to look for them too lol.
i can't say that all of these are well written and fit your standards, but these are some of the stories that made me gape in awe while reading it or even after reading it. some didn't, but still made me think of it.

Hey, do you have manga/manhwa/webtoon/whatever recommendations for really extremely well developed story lines, characters, etc where afterwards you were just in fucking AWE with the comic and had to think about it for some time? Or did this happen to you after reading a peticular comic?
I was impressed from A Shoulder to Cry On, Goja Dang, On or Off...
but only really felt that way lately when I read Killing Stalking and Smells Like Green Spirit. Probably also when I read Endless World and Dog Style but that's already a while ago.
Thank you for every recommendation!
