skorea has taken the bold approach of dealing with their distaste for gay people by just pretending they don't exist, but in general it's getting better, still really bad. Your best bet is gonna be subcultures in busan or seoul, anywhere else, like especially daegu, you're in for a bad time.

the homophobias of china and skorea are different tho, china has a vastly more hypermasculine form of homophobia whereas skorea is more of a "eww icky!" kind, take from that what you will. I think it has a lot to do with the sort of religious colonialism inherent to skorea (tons of churches everywhere), but a lot of the shamanists and whatnot are also just as homophobic. Pretty fucked generally. Anyway that's all different to china which has a sort of nationalistic machismo about it

EDIT: just recently there was a rona outbreak in seoul, specifically in itaewon, a foreigner/party district. Since theres a lot of foreigners its a good spot for gay clubs too, and a korean who had it went to one of such clubs and unfortunately spread it around. This lead to lots of antiforeigner (even tho he was korean) and anti-gay sentiment. Shit like that is pretty indicative.
