i feel like you'll also like the complex story with a similar historical vibe like this one

The one that I can't forget but also can not read again: The Beast Must Die

https://www.mangago.zone/read-manga/darkness_before_the_dawn/ has probably the most unique setting ive read. The artist flesh out the kowloon city really well and the life and culture in it
https://www.mangago.zone/read-manga/reunion/ I think about constantly how hauntingly poetic and melancholic this manhwa is. The plot is not extremely c complex but the way it was delivered amazes me.
And yes, proxy painter is also the first story that i really liked. The characters were complex, raw, and driven by human nature both good and bad, plot delivery and progression was smooth and properly paced. Each chapter has this raw emotional that u can relate from both mc and ml
For me its Truth or Dare and Murderous lewellyn's candlelit dinner. The build up plot and the twist which u cannot expect. Its really different from other story I've read. And also I love the depth of their narrative and story dialogue, its so poetic and so deep. There is also a grippling emotions, heavy yet not disturbing... wahh recommend me some stories like that tooo
