A Pink member Kim Nam Joo reveals the behind the story of the "A Year Ago" music video that she filmed with BEAST Jang Hyun Seung and fellow member Jung Eunji.

They released the music video yesterday on their official page and YouTube channel.

Kim Nam Joo revealed that the snow that they used for the shoot was all collected by the staff members exclusively so they could film the video.

An official also commented that the team had other plans for the music video, but because of the unexpected snow, they decided to incorporate it into the video.

This song is included in the 'A CUBE FOR SEASON' second album that was released on January 3.
