The boys of 2AM wowed their fans again with I Did Wrong. After thanking their fans on Youtube, the boys gave some more fanservice on the stage of Music Bank. The awesome choreography coupled with the catchy tune make for a great song. Unfortunately 2AM will be ending their promotions soon, so be sure to cherish the few stages they have left! Check out the performance below. http://www.youtube.com/watch?v=9FwKZ6X7OTo
