actually I don't think in korean pervert has the same meaning all the time 😭 By that i mean direct translation is not pervert, but in english the only similar word to wtv korean means is pervert. They use the word pervert a lot in many contexts. Like in english pervert has one definite meaning which is a bad person. But in Korean language it's used in many situations and most times it nothing like a bad person or a disgusting thing,,, infact its mostly "naughty person"
I saw you were confused at the "do re mi fa sol la" part 😄. So Baek said "do re mi fa sol la XI-U-MIN (she-u-mean)" what is a stage name of Minseok (the boy with the pink hair at this clip and the one who said "hawaii you" and "marshamallow" in this video). You pronounce his name "Xiumin" like "Sh u mean" (minus the space I use for better reading ;d). Not "shoe-mean" or "zoo-mean" like a lot of people do this. His name was supposed to sound chinese, because he was in the chinese promoting sub group (EXO-M). Well... Yeah. That's all. Sorry for my blabling and I hope you at least understand what I write, coz eng is not my first language.
