BTS is on temporary break as a group with three of its seven members currently doing South Korea's mandatory military service.

On Wednesday, BTS's management agency said the remaining four - RM, Jimin, V, and Jung Kook - have begun the process of military enlistment.

"This coming December... I'm leaving you for a short while to serve in the military," Jung Kook said in a separate message to fans on Wednesday.

"After I return, I promise that I will be where I always am, on stage - having grown."

With this, all seven members are expected to complete their service by mid-2025, analysts said.

Hybe, parent of BTS' management agency, benefits by BTS members' staggering enlistments and solo activities, allowing members who have served earlier to be active while others are away.
