What did STARSHIP confirm about SeolA and Eunseo?
Two short notices, posted minutes apart, closed a decade of agency ties for two WJSN members — and left the bigger question untouched.
STARSHIP Entertainment confirmed on September 17, 2026 (KST) that the exclusive contracts of WJSN (우주소녀 / Cosmic Girls) members SeolA and Eunseo with the agency have ended, announcing each departure in a separate notice posted to its official X account . The two posts were identically framed and deliberately narrow: they address agency status and nothing else.
In the notices, STARSHIP said it was "truly grateful to SeolA and Eunseo, who have been with STARSHIP for a long time," adding that it "will remember all the moments we shared and our precious memories for a long time" and wishing the pair "every step forward to be filled with happiness and good things" — the agency's only public statement on the exits .
What the notices do not say matters as much as what they do. Neither post mentions WJSN group membership, a lineup change, a disbandment, or a new agency for either member, and no next project was named . Both women debuted with WJSN on February 25, 2016 with the EP "Would You Like?", which is where the widely used "10 years" framing in Korean headlines comes from .
SeolA and Eunseo's decade-plus with WJSN, in their own words
SeolA counts her time with STARSHIP at 15 years, not 10. In a handwritten letter posted to her personal account on September 17, 2026, she introduced herself as someone "starting anew after leaving STARSHIP Entertainment, which I spent 15 years with" — a figure that folds in her pre-debut trainee years on top of the decade since WJSN's February 25, 2016 debut . The gap between the two numbers is the difference between a discography and a career.
Her letter was specific about what the agency years contained. "STARSHIP was always by my side through many first moments and precious memories of my life," she wrote, naming trainee days, first standing on stage as WJSN, and releasing music under her own name among those firsts, and adding that "all those moments have made me who I am today" (source: Topstarnews, 2026-09). She did not flatten the record into gratitude alone, noting "there was truly so much learning; there were days of joy and exhilaration, and days when things did not go as I wished."
"Though starting a new path feels unfamiliar and frightening, I will walk forward step by step with sincerity at my own pace." — SeolA, WJSN, in her September 17, 2026 letter (source: Topstarnews)
She closed by addressing WJSN's fandom, Ujung (우정): "I want to say this, too, to Ujung, who have always stayed by my side" . Eunseo's message was shorter. She said the decision to leave was not an easy one to settle on, and promised to greet fans again through good work . Neither message named a destination.
Both members are tied to WJSN's best-known singles — "Secret" (비밀이야), "Reach for You" (너에게 닿기를), "Save Me, Save You" (부탁해) and "As You Wish" (이루리) — but their recent work has diverged. SeolA joined the 2021 sub-unit WJSN The Black and solo-debuted in 2024 with the single album "Inside Out," alongside screen credits including a 2022 horror film ("Urban Myths") and a Netflix ghost-story series ("Goedam") . Eunseo has leaned toward acting, with film credits including "Ameba Girls and School Ghost Stories: School Foundation Day" (2024) and "Gwisi" ("The Cursed," 2025) ; in a November 2024 interview she described herself as "actress Son Joo-yeon, for now" (source: Xportsnews, 2024-11).
Does leaving STARSHIP mean leaving WJSN?
No — not automatically, and as of September 19, 2026 nothing says it has. Neither STARSHIP's two farewell notices nor SeolA's or Eunseo's own posts state that either member has left WJSN as a group, announce a disbandment, or name a new agency . The confirmed change is agency status only. Korean outlets covering the exits posed the 완전체 (full-lineup) question directly rather than treating it as settled — one report's headline asked plainly, "설아 은서 스타쉽과 결별… 우주소녀 완전체는?" ("SeolA, Eunseo split with STARSHIP... what about WJSN's full lineup?") .
WJSN's own history is the reason that distinction matters. On March 3, 2023, STARSHIP announced that eight Korean members had renewed — Exy, SeolA, Bona, Soobin, Eunseo, Yeoreum, Dayoung and Yeonjung — while in the same statement Luda and Dawon's exclusive contracts with the agency ended, and the WJSN contracts of the three Yuehua Entertainment-linked Chinese members, Cheng Xiao, Xuanyi and Meiqi, automatically terminated . Korean coverage at the time treated the three Chinese members as having formally left the group, but described Luda and Dawon as retaining the possibility of continued WJSN team activity despite no longer being STARSHIP artists . In this specific group, leaving the agency has already been shown not to mean leaving the lineup.
Applying the September 17 notices to that 2023 cohort produces the following public picture:
| Member | STARSHIP status (public reporting) | Since |
|---|---|---|
| Exy, Bona, Soobin, Yeoreum, Dayoung, Yeonjung | Tied to STARSHIP from the 2023 renewal | March 3, 2023 |
| Luda, Dawon | Outside STARSHIP management | March 3, 2023 |
| SeolA, Eunseo | Outside STARSHIP management | September 17, 2026 |
| Cheng Xiao, Xuanyi, Meiqi | WJSN contracts auto-terminated (Yuehua-linked) | March 3, 2023 |
That leaves four of the ten Korean-side members announced in 2023 now outside the agency . The remaining variable is the six who renewed in 2023 and whose second-cycle status STARSHIP has not disclosed — the agency has said nothing about whether Exy, Bona, Soobin, Yeoreum, Dayoung and Yeonjung have re-signed, are negotiating, or are approaching the same decision point . Until either STARSHIP or the artists' representatives address it, WJSN's long-term agency structure is not visible from outside, and any claim about the group's future lineup is inference rather than reporting.
What's next: WJSN's 'Bloom hour' anniversary and open questions
The September exits land under seven months after WJSN's 10th-anniversary single "Bloom hour," released February 25, 2026 and written and composed by leader Exy as a song for the fandom Ujung . It was the group's first new music in roughly four years, following 2022's "Sequence," and STARSHIP's own artist page lists the release date as 2026.02.25 . Commercially it was quiet: "Bloom hour" did not chart on the Circle Digital Chart and peaked at No. 27 on the Circle Download Chart, with fans criticising what they read as minimal promotional backing after the release landed two days behind labelmate IVE's full album . Luda and Dawon did not take part in it.
Four things remain unresolved as of September 19, 2026:
- Membership. Neither STARSHIP nor either woman has said whether SeolA and Eunseo remain WJSN members .
- Next agencies. No new label has been named for either member in any source reviewed .
- The other six. Renewal status for Exy, Bona, Soobin, Yeoreum, Dayoung and Yeonjung is undisclosed .
- Group operations. Whether STARSHIP will keep organising WJSN activity that involves members it no longer manages is unstated.
The practical takeaway for Ujung: treat STARSHIP's official SNS and each member's personal accounts as the only reliable channel for the next confirmation. Every concrete detail in this story so far — the two September 17 notices, SeolA's handwritten 15-year letter, Eunseo's shorter message — arrived that way first, and the entertainment press filled the gaps with inference afterward. Until one of those accounts posts again, WJSN has six members under STARSHIP, four outside it, and no announced disbandment.

Frequently asked questions
When did SeolA and Eunseo's STARSHIP contracts end?
STARSHIP Entertainment posted two separate farewell notices to its official X account on September 17, 2026 (KST), one for SeolA and one for Eunseo, confirming that both members' exclusive contracts with the agency had ended . The notices were short and identically framed, thanking both members for their long tenure and wishing them well as they begin anew . No effective date beyond the announcement day was given.
Are SeolA and Eunseo leaving WJSN?
Not confirmed. STARSHIP's notices and both members' personal posts address agency status only — neither says the pair have left WJSN, and no disbandment or lineup change was announced . At least one Korean outlet posed the 완전체 (full-lineup) question directly in its headline rather than treating it as settled . The group's own history supports caution here: when Luda and Dawon's STARSHIP contracts ended in March 2023, Korean coverage described them as retaining the possibility of continued WJSN activity .
Why are headlines calling it '10 years' when SeolA said 15?
The two figures count from different starting points. Headlines use ten years because SeolA and Eunseo both debuted with WJSN on February 25, 2016 with the EP "Would You Like?" . SeolA's own figure appeared in a handwritten letter posted the same day: "I am starting anew after leaving STARSHIP Entertainment, which I spent 15 years with" — a count that includes her pre-debut trainee period at the agency . Neither number is wrong; they measure different spans.
Which WJSN members are still with STARSHIP?
Six members from the 2023 renewal cohort remain publicly tied to STARSHIP: Exy, Bona, Soobin, Yeoreum, Dayoung and Yeonjung . That cohort originally included eight Korean members who renewed on March 3, 2023, with SeolA and Eunseo among them . The current renewal status of those six has not been disclosed, so WJSN's longer-term agency structure is not visible from outside STARSHIP and the artists' representatives.
What are SeolA and Eunseo doing next?
No new agency has been announced for either member, and neither farewell notice named a next project . SeolA has a track record to build on: the 2021 sub-unit WJSN The Black, a solo debut in 2024 with the single album "Inside Out," and screen credits including a 2022 horror film ("Urban Myths") and a Netflix ghost-story series ("Goedam") . Eunseo has leaned toward acting, with film credits including "Ameba Girls and School Ghost Stories: School Foundation Day" (2024) and "Gwisi" ("The Cursed," 2025) ; in a November 2024 interview, she described herself as "actress Son Joo-yeon, for now" (source: Xportsnews, 2024-11).
