SEVENTEEN's Seungkwan and Dino Enlist October 26: The Final Two Enter Military Service Together

SEVENTEEN's Seungkwan and Dino enlisted in the South Korean Army's military band on October 26, 2026, marking the final chapter of the group's mandatory service cycle. Pledis Entertainment confirmed the SEVENTEEN military enlistment date in August, noting both members would enter together and asking fans not to gather at the enlistment site out of consideration for the other inductees and their families. The two join Mingyu, who began his own service in September — the last three members of SEVENTEEN to formally step away from group activities during the enlistment period.

Both Seungkwan and Dino will serve in the Army as military band members — a track that involves musical performance within the armed forces and is among the most public-facing service assignments available to Korean men. Pledis Entertainment's pre-enlistment statement acknowledged the significance of the date and highlighted that the group had prepared content in advance so that CARAT — SEVENTEEN's fanbase — could remain connected throughout the members' absence. A variety of pre-produced material is scheduled to roll out across the enlistment window, following the model that HYBE has used for BTS members' service periods.

SEVENTEEN had already navigated one high-profile enlistment cycle before October 26. Jeonghan, who enlisted in September 2024, completed his mandatory service and was discharged on June 25, 2026 — the first member to return. His reunion with SEVENTEEN was marked by the rapid announcement of the JXJ unit project with Joshua, culminating in the DREAMSCAPE mini album released October 19. The pattern — enlist, serve, discharge, then re-enter creative activity quickly — has become the standard HYBE playbook, and there is no indication that Seungkwan, Dino, or Mingyu's returns will deviate from it.

Of the three October–September enlistees, Mingyu's service track differs most significantly in duration. He is fulfilling his obligation through alternative (social) service rather than active military duty, which carries a longer total period — expected to extend to approximately June 2028. Seungkwan and Dino, as military band members, are on a shorter active-duty timeline and are expected to be discharged in late April 2028, roughly two months before Mingyu. The stagger means a brief window where Seungkwan and Dino may return to SEVENTEEN activities before the full lineup is restored.

With Seungkwan and Dino's enlistment, SEVENTEEN's service cycle is now fully underway. The group's thirteen-member architecture means these absences reshape every subunit arrangement and live performance configuration for the duration. Previous enlistment periods for BTS and EXO demonstrated that agencies can sustain commercial momentum through a combination of pre-produced content, solo activities, and unit projects — and SEVENTEEN's own unit output in 2025 and 2026 suggests the same strategy is firmly in place. The DREAMSCAPE release arrived just a week before the October 26 enlistments; the timing was deliberate.
