Ummm this was the first kpop video I ever saw lol. This is literally what got me into kpop. It took me forever to figure out that they had a music video for the song they were dancing to, and that this dance practice was actually them and not just a cover done by someone else, and that the reason they had two music videos for Lucifer is that one was in Japanese and the other was in Korean. Man, kpop the good old days. Takes me back to when I was clueless.
