I can only judge Heechul based on what I've seen (and that's mostly Bonamama and what followed), but so far he's always come across as very unenthusiastic, very arrogant. I haven't heard him talk, though, only in performances so he might be an absolute darling and I just don't know it, but I don't find him attractive at all. oO

D'aww, the vids not working for me (Sony Music Content blabla-- not working in "your country") but spamming with biases is totally fine. ;D

Music-wise, I love KT the most but I get my share of happy pills with the other groups. XD You might want to keep an eye on Kis-my-ft2, maybe, since they're promoted very similarly to KT (sexy) and their songs are great even though they're not debuted yet (*hopes*). They are also the ones Kame is biting in his vamp-solo. ;D (and there is fic~)

I've been sort-of-kind-of keeping up with SuJu and Shinee, through a few people on my flist. I like their music and the choreos (I love dancing in general) but the speech-barrier (even though my japanese isn't anything to write home about) and the crazy fandom has been keeping me from actually doing more than watching vids and occasionally reading fic. Mainly Big Bang, who are the only ones I can tell apart. XD
