The girl group released the holiday track last month, and the MV was filled with lovely holiday festivities and energy. In the making-of video, the girls goof around with directing, pose for the camera, and give as much fan service as possible. Different from the "Twinkle" concept, you get to see plenty of the Lovelyz' members silly sides as well.
