On December 23rd, SM introduced Kai, the first member of EXO. Judging from the teaser clip, he’s quite the fluid dancer, and is sure to capture many fangirls’ hearts with his mysterious charisma.

SM had explained that they were going debut a Korean-Chinese boy group who would come out with the same song on the same day. It seems that the Korean group will be called EXO-K, while the Chinese group will be called EXO-M (much like how ‘M’ stood for ‘Mandarin’ in Super Junior-M).
