well, Kara is the first group that i watch MV in Kpop.
at fisrt, it was "if you wanna" when they had 4 members ( with sunghee). At that time, i'm not really into Kpop, so i just like the song, and that's all.
recently, when a friend of mine recommend me to listen to Kpop, i remember of "Kara", and go find some MV of them, it was "Mister" that got me immediately addicted to them :x
and then i started to find more infos/videos/ shows/ MV or anything relates to them really really love them, i even cried when they claim the Music Bank no.1 xD
