Though it hasn't been long since they've finished "Bad Girl Good Girl" promotions,�miss A is already preparing to make a comeback with a brand new track! On the 17th, AQ Entertainment has revealed their first teaser photo through their official website and in true teaser fashion, we can't really see anything. But from what we can make out, their outfits definitely look more quirky this time around. The single cover also says "Step Up," so we're guessing it's safe to assume that it's probably their title track. AQ Entertainment said,�"This is miss A's comeback teaser photo. Please cheer on miss A since they will be back with a shocking new look." I wonder what their new concept will be.
