SEVENTEEN's Hoshi and Woozi announce enlistment plans following Wonwoo
During SEVENTEEN's annual fan meeting, "SEVENTEEN in CARATLAND," held on March 20 and 21, 2025, members Hoshi and Woozi revealed their plans to enlist for mandatory military service.
During the fan meeting, Hoshi addressed the audience, sharing that both he and Woozi had received their enlistment schedules and would commence their service later in 2025. He reassured fans by stating,
"Woozi and I have received our military enlistment schedules. We’re planning to enlist in the second half of the year, so we’ll be able to spend the 10th anniversary together and make some fun memories before we go. […] I’ve never said this before, but I’m really grateful to S.Coups for keeping all 13 of us together since we were young. […]"
Hoshi continued:
"Maybe because it’s time to enlist, every performance feels even more precious. It’s not like we’re disappearing—we’ll continue to work hard even after we return. People say nothing lasts forever, but SEVENTEEN is going to take on that challenge. We’ll need your support to do it."
Prior to their enlistment, Hoshi and Woozi are actively engaging in musical projects. They recently released their first single album, Beam, under the subunit Hoshi x Woozi.
