I'm sorry, but while there are some chubas who can speak Korean in a pleasant way (Kronii being one of them), the language itself just sounds like dogshit. Same with Chinese. And Indonesian. And to a certain degree even English, barring this here wholesome country accent.
I'm probably ginormously biased because language and culture go hand in hand, and I have years of fawning over Japanese culture under my belt, but I've yet to hear a language that sounds as pleasing as Japanese. Then again, I'm not a big europhile so there may be a European language that sounds nice. I just can't think of one off the top of my head.
Don't get me wrong, the Korean written language looks fun. It's just that their culture seems entirely derivative while Japan and even China are producing entertainment for genres native to their countries.
All I know about Korea is MMOs, TV dramas and boy bands, and I don't have any time nor need for MMOs.
