This person is saying they've grown up in Korea and are from a traditional, wealthy family. There's a certain way male Koreans - even if they're westernised - speak/type/write. You can feel them. The westernised ones who are taken in by this SJW shit are assholes. They have a certain smugness to them which is specific to Korean men. There's a certain way Korean men who grew up wealthy speak, even if they're americanised and it's not like a giddy bean flicking fujoshi.
Koreans who are very traditional, also wouldn't be into anime. Traditional, wealthy Koreans are usually more hateful of Japs than your average Korean. This person sperging about anime like a typical weeb is not Korean who grew up in a traditional family in Korea. I didn't even grow up in Korea or Japan and I still have that conservative asian mindset drilled into me. This person lacks all of that. They still could be some kinda asian, but they're so badly westernized.
I suspect more so, that this person is some kinda Hispanic or South East Asian fujoshi. I could be wrong, I doubt it tho.
It goes to school, but is running a business for its family? Get out of here.

정말! 정말! Is it true? YES! Okeydokey Yo! 정말!? YES! Okeydokey Yo!
Nigger pls.
Their Korean is basic, not structured, it's just words and they're words that are conversational. I mean if you speak Korean, as a native, you're going to longform that shit. Not just flick some words in here and there.
I mean, I could understand it if it's replying to a comment and you're too lazy to switch the keyboard to another language so you just rely on your phone's wordbank, but this person is only using single words. Disconnected.
This isn't a Korean native who grew up in Korea, nor is it a man. This is a weeb with a basic set of Korean words in her vocab, copy and paste and a yaoi fetish.
I could go on about the cultural lack of gookness here, but it's pointless since it's obvious to everyone it's a larper.
