Last November, Rainbow colored up the kpop world three months ago with their debut album, it looks like it's time for the girls to wrap up promotions and step off the stage for now. Although their title track Gossip Girl received mixed reactions on the international front, Rainbow has generated quite a fanbase as time progressed; Not Your Girl ensnared more fans with its exotic charm and catchy tune. In a recent meeting with reporters, Rainbow expressed disappointment that their first set of activities were over. "The next album will have a concept that expresses our personality more." The seven gals have been flooded with endorsement invitations, so we'll continue seeing these girls around even if they aren't performing on music stages. Rainbow has shown a cute yet sexy style with their first album; what kind of concept would you like to see from these girls next? UPDATE: Check out their goodbye performance on this evening's episode of Inkigayo: http://www.youtube.com/watch?v=kCktNHZTW7s
