THE last four members of South Korean megagroup BTS who have yet to undertake their mandatory military service have begun the process of enlisting, the K-pop stars’ label said today.

All able-bodied men in South Korea must serve at least 18 months in the military and, after a years-long debate about whether BTS deserved an exemption, Jin, the oldest member of the group, enlisted last year, followed by his bandmate J-Hope in April.
