Topp Dogg released their MV for "Annie," which is short for "anniversary" as the boys celebrate the one year mark since debut!

Although they are celebrating this milestone in their career, they decided to take a step back and rewind the years for a retro, 90's concept in this special comeback.  The boys dress in oversized outfits and show off equally big hairstyles, all of which were vastly popular in South Korea during the 90's.
