I think the official translation is by an american company for americans users, so they will localise even the drawings
But yeah, americans in general are probably the least worldly people on earth :p they're used to everyone just changing things to align with their way of things
As an American I agree with everything you said and honestly it's very annoying. Like just put footnotes or whatever to tell readers what this word means. No need to try and equate everything by western or American standards. It's very off putting seeing this is set in SK and yet the currency in his bank account is USD, like come on now.
I'm glad this finally got translated officially, though I'm questioning some of the translators they've been hiring lately. The gen z talk and using western phrases etc, also why did his bank account say USD? That type of stuff with recent manhwa has been kind of annoying. But anyways this story seems fun so I'm glad it is getting updated, thank you uploader!
