Although they grabbed top spots on music charts with their new single "So Cool", the ladies of SISTAR aren't quite satisfied yet. Trying their best to gain new fews, SISTAR posed cutely for the camera with pleading expressions. Member Bora tweeted,�"Can't you please listen to 'So Cool' at least once? Please!", before she attached this quirky photo set. Followers on Twitter commented, "After seeing only charismatic images from you, [this new look] is refreshing," "I'm going to download the song right now," and "So cute." SISTAR will be performing "So Cool" for the first time this week on Mnet's 'M! Countdown'. Source + Photos: Tv Daily via Nate
