Although they revealed their MV teaser earlier, the MV is still not yet out, but you can enjoy the songs off their single in the meantime.
This 6-member group announced their upcoming debut through a special performance at the '2013 Dream Concert', but it wasn't until today that they dropped their single.
If some of the members look familiar to you, it may be because two of them (Taehee and Useung - former name Jino) are from the boy trio that debuted back in 2011 called BB. Boys. Useung also featured in the recent past weekend drama 'Hundred Years' Inheritance'.
The boys will be debuting on 'M! Countdown' later tonight, so catch them on the show and stay tuned for their MV release!
