After releasing their music video for "Alone" and performing on Mnet's M! Countdown, SISTAR's Hyorin has now shared a practice attack video.

While the ladies of SISTAR are hard at work practicing the choreography for "Alone", Hyorin barges in and asks her fellow members what they're doing. She displays some of the choreography for "Alone" and also showcases her wonderful vocals for the camera.
