Music VideoEdit

The high definition music video for the single, released on September 3, 2009, featured the girls dancing on various theater-themed sets. They start by coming and getting off their pink car and dancing to the beat in front of a lighted theater entrance during a night. As the song starts, Victoria, Amber and Sulli enter the theater through the door while Luna and Krystal stay behind to sing first two verses respectively. Scene shifts to individual sets. Amber, dressed as a ringmaster is on a dark stage with fire pits in front, red carpet beneath and huge hanging doors as decors at the back. This reflects her name which means 'fire'. Victoria, wearing a formal pink dress and jewelry, is in a room with glittering mauve colored walls and posh pink and white hanging ornaments. Luna, wearing a golden dress, is walking up a black staircase leading to a crescent shaped shimmering golden seat, reflecting her name which means 'moon'. Sulli, dressed in casual form, is in a bed room with blue walls, red carpet and a large teddy bear hanging from the wall. Krystal, dressed in formal black, is in a room with many hanging crystals and mirrors at the back. As song proceeds, girls discover that their rooms are connected in a way or another and start greeting each other. As the song comes to an end the girls come out of the theater laughing and drive off in their car.
