The video clip not only hints at the video to come, but also a bit of the tune included in their upcoming repackaged mini album, 'Again 1977'.

It's said that this is a teaser that gives us a first listen at the ballad version of their title track '2013 What Should I Do', called, '1977 Don't Remember', which is also included in their upcoming mini album.

"2013 What Should I Do?" itself is a dance track that is the work of Shinsadong Tiger and Polar Bear and features sampling of the song that won the traditional University Song Festival back in 1977, Sand Pebbles' "What Should I Do?".

As this video is already hinting at a dramatic story line to come, it's only fitting that it deserves a premiere of its own, so the girls will be holding an event on the day of the release, December 2nd, to screen their video for 60 fans on the big screen.

The musical-like video is said to be 9 minutes long and there will also be a 10 minute production process footage.
