On September 24th, XUM's debut song 'Ddalala' was released through various music sites at noon.

“Ddalala” was composed by hit composer Sinsa-dong Tiger to enhance its completeness, and XUM's three-person three-color personality was added to predict explosive synergy.

In particular, XUM is going to enjoy the eyes and ears of listeners, boasting a powerful performance and solid singing ability through 'Ddalala', which borrows the Jersey Club genre, which is the first attempt from existing idol music.
