According to Core Contents Media, "Hide and Seek" is a ballad track composed and written by Park Duk Sang and Park Hyun Joong with acoustic guitar accompaniment. The song is an unreleased track that is part of T-ara's 8th repackaged album, 'Again 1977', that the girls and their agency had planned to reveal at the end of this month. However, thanks to the eager response they've had with "Do You Know Me", they've decided to pull up the release date!

For the excited fans, reps added, "Through 'Hide and Seek', T-ara will show a new image... They will transform into winter girls, different from their concept for 'Do You Know Me' and 'Number Nine'."

Don't run or hide so you won't miss out on the release of "Hide and Seek" on the 14th!
