Yea i'm Korean! lol thought you'd be able to catch that when I said I was fluent to some extent haha.
Mandarin is a hard language though in terms of writing and speaking I heard.
Well if you are pretty serious in learning Korean and becoming fluent I can always help out if you need anything clarified over the net.
I'm a bit loose with proverbs or traditional forms of Korean but anything said on K-Drama or K-Variety shows I understand about 95-100% which is pretty much day to day Korean language.
