With respect of people who do not speak Korean I'd like to write in English, although it contradicts my belief (I hate people who speak English in public in Seoul or whatever, to show off their english skills.. but i'll follow the rule--common space, common language).
Hello there, I'm hunj (either HUNJ or hunj, not Hunj or such), pronounced HEON-j (the "hun" part sounds like "hon" as in "honey").
I'm 17 years old (for your convenience, "born in 1990") and goes to a private high school in New Hampshire as an international student from Korea (so it solves your question, I'm 100% Korean, speak Korean as my first language).
While other Korean international students tend to be pretty much stereotypical international students (e.g. brand whore), I myself is an otaku, or so-called, "Odeokhoo (lol)."
I do not cosplay but rather photograph cosplayers. As I am a senior in high school next year and I am pretty much loaded up with SAT prep and college stuff, I think I won't be able to go to Seoul Comic World this summer (maybe this december!).
Since I am a boarding student, there's almost no possiblity to go to anime cons in the states. I have several american friends who are into anime so I might be able to attend with them
Anyway, I'm so glad to meet you guys.
