Firstly, i'm not a teenage fangirl who just knew kpop for 1-2 days. at least not anymore XD So if you ask me who is who in any rookie groups, or whose this song belongs to whom, sincerely i'll answer i don't know lol
because honestly i'm kind of fed up to the kpop-whole-thing these past years, however i still and will always fond to some groups like DB5K, Shinhwa, Mblaq, Rain and some korean indie bands.

i'm majored in korean language, so if you have anything to ask about some word or grammar, i do not mind to help you :D well, i know there's so much online dictionary, even you could search in on google and taraaah you'll find whatever you need XD but, just in case you wanna make sure of something, i'd like to help^^
but pardon me for my bad grammar, since english isn't my mother language >_<"
