On November 26, the unit - comprised of Korean member Yoonhye, Taiwanese member Chiayi, and 'Produce 48' contestant Kim Do Ah - released their debut single "Milkshake" as well as its bright and quirky music video.

"Milkshake" has a retro feel that is augmented by the song's heavy synth-pop vibe, and is accompanied by a fun 'shake' dance. The song is sung from the perspective of girls who want a love as rich and sweet as a milkshake.

Among those who worked on the song include producer/songwriter Nassun (KARD's "Oh NaNa" & "Don't Recall"), music video director Zanybros' Hong Won Ki (Wanna One's "Boomerang"), and 'Produce 48' judge and choreographer Bae Yoon Jung.
