The girls of FIESTAR have come together to introduce their upcoming second single album, 'We Don't Stop'.

The group previously revealed the track "Sweet Love" featuring Sweet Sorrow's Kim Yeon Woo the other day to give fans a taste of some of their new material. This new video was released for CSI (Coming Soon Interview) , a series that takes a behind-the-scenes look at artists who are making a comeback or debut.
