SEVENTEEN member Vernon has released a new solo song, I’ll Be Back, as he begins his mandatory military service in South Korea. The single arrived on August 20, the same day he entered a training center to start basic military training.

A release issued alongside the song confirmed Vernon took part in writing and composing the track. Built around an electronic pop sound, I’ll Be Back gives fans new music as he steps away from regular group activities during his service period.

Vernon had already introduced the song during a V8 live performance in July, giving listeners an early preview before its official release. The title also carries added meaning because of the timing, pointing toward his eventual return to music activities.

After completing basic training, Vernon is expected to continue his service as a social service agent. His enlistment follows a period of recent activity that included work with fellow SEVENTEEN member The8 as part of the V8 unit.
