The boys of 24K were "Super Fly" in their first teaser video, and in their second one, they bring it up a whole 'nother notch.

In the second teaser, the members are even more like 'bad boys', as they graffiti, push each other around, and break TVs. The Korean name of their song is 'Nal-la-lee' which roughly translates to a bad kid or a student. That's exactly what the 24K members look like in these teasers, except in the coolest way possible.
