[3] Hyomin revealed the name and concept photo of the new album through SNS on February 25 and confirmed the name of the new song "Sketch" .

On March 18, Hyomin held her first release showcase for the album at Shinhan Card Fan square in Seoul.

"Gold" is a vocal-based song that features sophisticated synth sound and piano tone.

It is about rhythmic vocals that bring out the mood of the song and vividly express the drive with a loved one.

It's described as a song that you can relate to if you have ever experienced love conveying a contradictory and implicit meaning that 'we are the only ones who don't know our story'.

Guitarist Lee Tae-wook, a member of the band Soran, participated in the song's recording.

On March 1, 2016, MBK Entertainment released a promotional photo of the album teaser.

Tamar Herman from Billboard praised the song's atmosphere and its "warm embrace of the hazy synths and layered strings paired with the T-ara member's breathy cooing sounds" pointing out the similarities to British pop singer Sia's songs.
