Winter’s latest updates are best understood as two connected threads: a past health-related concert absence that raised fan concern, and aespa’s current run of 2026 music and tour activity. The available reports do not provide a new medical update on Winter in May 2026, but they do show that she remains part of aespa’s listed group activities around the upcoming album cycle.
The phrase Winter health concerns points mainly to the November 2025 Bangkok concert report, while the newer May 2026 updates center on aespa’s second full-length album, its pre-release single, and a large-scale world tour schedule.
Winter’s Recent Status at a Glance

The clearest health-related item in the available material dates to 2025. StarNews reported that Winter did not participate in aespa’s November 16, 2025 performance at IMPACT Arena in Bangkok, Thailand, due to health reasons. SM Entertainment said she visited a hospital after the previous day’s performance and was diagnosed with cold and flu-like symptoms, with a doctor advising sufficient rest. The company described the decision as one made with “the artist’s health and safety” as the top priority.1
That report explains why Winter’s condition became a point of attention, but the later source material shifts away from medical details and toward aespa’s group schedule. The May 2026 updates do not state a new health diagnosis, treatment, or absence. Instead, Winter is included as a member in aespa’s ongoing album activity around 『LEMONADE』 and the pre-release single “WDA (Whole Different Animal) (Feat. G-DRAGON).”2
| Date | Update | Why it matters |
|---|---|---|
| November 16, 2025 | Winter missed aespa’s Bangkok performance at IMPACT Arena after cold and flu-like symptoms were diagnosed, and the concert continued with the other three members.1 | This is the source-backed basis for the health concern discussion. |
| April 21, 2026 | Chosun Ilbo reported aespa’s schedule poster for the second full-length album 『LEMONADE』, including teasers, mood samplers, a highlight medley, and music video teasers before release.3 | It placed the group back into a structured comeback timeline. |
| May 11, 2026 | aespa Japan Official Website announced the release of “WDA (Whole Different Animal) (Feat. G-DRAGON)” and its music video as a pre-release single for 『LEMONADE』.2 | This is the latest official music update in the provided material. |
| May 29, 2026 | 『LEMONADE』 is scheduled for release at 1 p.m. KST.4 | This is the next major album milestone after “WDA.” |
| August 7-8, 2026 | aespa is set to open “2026-27 aespa LIVE TOUR – SYNK : æ” in Seoul.5 | The comeback is being followed by a wider live schedule through 2027. |
From Health Concern to Comeback Activity
The health concern report was specific and limited: Winter was absent from one Bangkok concert after cold and flu-like symptoms were diagnosed, and SM Entertainment said rest had been recommended. The source material does not say she left aespa activities overall, and it does not provide a later standalone health bulletin. That distinction matters because the subsequent reports are about aespa’s broader comeback cycle, not a continuing medical issue.
The 2026 activity trail begins with the album buildup. Chosun Ilbo reported that aespa had released a schedule poster for 『LEMONADE』 ahead of a May 29 comeback, with promotional content planned in stages before the album release. The listed rollout included teaser images, mood samplers, a highlight medley, and music video teasers, based on material provided by SM Entertainment.3
The pre-release single then gave the comeback a more concrete musical update. On May 11, 2026, aespa Japan Official Website announced “WDA (Whole Different Animal) (Feat. G-DRAGON)” as a pre-release single from the second full-length album 『LEMONADE』, alongside the release of its music video. The official notice described the track as a hip-hop dance number and directed fans to reservation and pre-save links for 『LEMONADE』.2
Other coverage added timing and participation details. allkpop reported that the “WDA (Whole Different Animal)” music video was released at 6 p.m. KST on May 11, 2026, and said G-DRAGON featured on the song and took part in making his rap. The report also noted that the video was released through official platforms including the SMTOWN YouTube channel.6
What Comes Next for aespa
The next confirmed major date in the source material is the full album release. Soompi’s updated coverage lists 『LEMONADE』 for release on May 29, 2026 at 1 p.m. KST, after the May 11 pre-release of “WDA (Whole Different Animal).” It also notes that the tracklist was revealed on May 10 and that a G-DRAGON featuring teaser was part of the earlier schedule.4
After the album cycle, aespa’s live schedule expands into a new tour. Billboard Korea reported that aespa will launch “2026-27 aespa LIVE TOUR – SYNK : æ” with Seoul concerts on August 7 and 8, 2026. The tour is planned to continue into 2027 and cover 25 major regions around the world, following the release of the group’s second full-length album.5

Taken together, the available updates show a shift in focus from a documented November 2025 health-related absence to aespa’s active 2026 comeback calendar. The record supports caution in wording: Winter’s health concern was reported around the Bangkok concert, while the newest source-backed developments place her within aespa’s ongoing 『LEMONADE』 era, the “WDA” pre-release, and the group’s upcoming world tour plans.
