Super Junior-M Swing teaser video

Okay, looks like Super Junior-M is going to release another MV before Super Junior makes their eventual(?) comeback. Swing is the title of the song and march 21 is the day it will be released. The teaser honestly doesn't tell us a whole lot about the actual song but it does tell us that Super Junior-M would be terrible employees. They can sing, they cane dance, but don't hire them to work in an office cause they wouldn't know what to do. Poor guys. March 21 ya'll. This weekend.
