All of the members of the group are in military service.

Fans of the K-pop band have known for a long time that its members would all serve in the South Korean military. A potential reunion concert for the members of the band is at least a year and a half away. It took about 547 days, 13,128 hours or 47 million seconds for the group to sign up. The first two members enlisted a few months before the last two. The band's management said last year that they would return around 2025, but before then, the group's members could perform informally for their fellow troops.
