It doesn’t bother me too much , tho they’re usually presented as stoic to it if not oblivious lol , maybe it’s a Korean quirk , but I guess since they don’t “commit” flirting is just something that’ll happen as a part of life
Altho “dense MCs” for JP manga too, I saw one Korean WEBTOON where one charas inner thoughts were straight up said “men and women can never be just friends” so hopefully that’s not too reflective of actual Korean culture bc that’d be a pain (esp if ur gay dealing with comphet but that’s a whole nother issue)
It would be interesting if he was invited to a wedding at some point if not a friend who’s been married for a few years having him design a home for them as like an anniversary gift or something lol
