I know many people are creeped out about age gaps between adults. But what about Korea's entire "oppa" culture? Even underage girls use it to refer to older boys and men. If a Korean woman or transwoman is interested in a Korean man she will call him "older brother" in their language. Japan has the whole oniisan thing, which has incestual undertones. But apparently Koreans think nothing of it. Probably because they are desensitized. ifans seems to be turning a blind eye to it.
