yesss they're finally debuting ;; I've been waiting forever
jaewoong's profile is here and here is kanto's. Kanto released a song last year featuring Sunggyu & you can listen to his mixtapes here and here. They dance pretty well too (kanto is in white, changwoo has the bandana around his head and his hair is parted down the middle, jaewoong is in grey)
