The group previously achieved the number 1 spot two years back, with their debut release, Twinkle.

[5][6][7] During an interview with Billboard, the three singers expressed, "This album was really personal for us and it was fun...to put out a much more raw side of our music...the music we put together has so much more layers, so much more depth to it in terms of sound, choruses or harmonizing together....Our main goal was to not be visually entertaining, but be vocally entertaining.

[26][27] The group made some radio and television appearances such as on MBC's "Sunny's FM Date",[28][29] or KBS2's You Hee-yeol's Sketchbook, where they sang a rendition of Destiny's Child's "Cater 2 U".

[30] The single track "Whisper" was released on September 13,[32] peaking at number 4 on Gaon's weekly chart.

[4] Tiffany described it as "a rhythmical song that has a big brass sound that stands out with a funky groove, soul, and is overflowing with energy".
