Consisting of six songs that fall mostly in the R&B genre with influences from hip-hop and pop, Kick Back featured the participation of various songwriters and production teams that have worked with SM previously, namely Alawn, Jasmine Kara, Bobii Lewis, Ebenezer Fabiyi, Dsign Music, Hyuk Shin, Simon Petrén, Cazzi Opeia, Ryan S. Jhun, and others.

It is the final WayV album and overall NCT release to feature Lucas due to his hiatus and eventual departure in 2023.

The lyrics convey the message of "gathering together in a secret place that only belongs to us, enjoying freedom, and planning the future together".

A self-made practice video was then released by WayV's member Ten on his Instagram account which racked up more than six million views in just three days.
