LE SSERAFIM are stepping into a new chapter with their second studio album PUREFLOW Pt.1, arriving May 22, 2026 via Source Music and HYBE. The rollout has been marked by cryptic teasers, shifting title-track strategy, and a growing sense that the group is pushing deeper into experimental pop territory.
The 11-track project introduces “BOOMPALA” as its official title track, replacing earlier expectations that “CELEBRATION” would lead the era. A surprise collaboration with Aliyah’s Interlude on “Saki” adds another layer to a tracklist that blends high-energy pop, atmospheric cuts, and genre-crossing production choices.
Release Timeline and Early Teasers
Promotion for PUREFLOW Pt.1 began on April 8, 2026, when HYBE and Source Music launched a series of visual hints across social platforms. By April 13, the group officially confirmed the album title and release date, locking in May 22 as the next major milestone in their post-Hot era.
Momentum accelerated on April 24 with the pre-release single “CELEBRATION,” which introduced a darker visual identity and a more fragmented sonic structure than earlier LE SSERAFIM releases. That shift continued into the album rollout, where “BOOMPALA” ultimately emerged as the centerpiece track.
Kim Chaewon’s Participation and Promotional Hiatus
Member Kim Chaewon is credited across the recording sessions and participated in the “CELEBRATION” promotional cycle. Source Music confirmed, however, that she will sit out PUREFLOW Pt.1 promotions due to a neck injury, marking a notable adjustment for the group’s upcoming performances and media appearances.
Tracklist and Concept Direction
The full 11-track listing positions PUREFLOW Pt.1 as one of the group’s most structurally ambitious releases to date. Alongside “BOOMPALA,” the album includes “Creatures,” “iffy iffy,” “Sonder,” and “Irony,” as well as the Korean-titled “우리 어떻게 더 사랑 수 있을까,” which translates to a reflective question about sustaining love.
“Liminal Space” closes the project.
Physical Editions and Collectors’ Push
PUREFLOW Pt.1 arrives in an unusually large range of physical formats, including 16 total versions spanning Birch Scar, Yusu Lily, Peony Room, Tri Accord, six Compact editions, multiple vinyl variants, Weverse Albums QR editions, and NFC Mini Camera versions.
Such scale reflects the group’s expanding collector-driven market, a strategy that has already fueled million-selling performance on previous releases like Unforgiven, which debuted at No. 6 on the Billboard 200 in 2023.
Chart Momentum
Commercial expectations remain high following Hot, which debuted at No. 9 on the Billboard 200 in 2025 and extended the group’s streak of consistent U.S. chart entries. Collaboration single “Spaghetti” featuring J-Hope also reached No. 50 on the Billboard Hot 100, reinforcing their crossover appeal.
