LE SSERAFIM has released a teaser for “BOOMPALA,” the title track from the group’s upcoming second full-length album “PUREFLOW” pt.1, moving the comeback campaign from timetable announcements into music-preview content. The album and the “BOOMPALA” music video are scheduled for release on May 22 at 1 p.m. KST, following a staged promotion plan that began with the official schedule reveal in early May. 1
The teaser is tied to the “Just BOOMPALA” item on the group’s promotion timetable, which was listed for May 8. Billboard Japan’s schedule summary places the first “BOOMPALA” preview before the next campaign step, “BOOMPALA Pavilion,” on May 11, followed by concept content and music video teasers later in the month. 2
“BOOMPALA” Teaser Moves the Campaign Into Preview Mode

The first look at “BOOMPALA” was reported as a teaser that opens with Chaewon listening as Yunjin says, “I’ve just got a lot on my mind.” Chaewon answers, “Just stop,” and later says, “They will. Want to go dance?” before the clip shifts into a dance segment and a short preview of the title track. 3
The source material does not provide full lyrics, production credits, choreography credits, or a complete musical description for the song. What is confirmed is narrower: “BOOMPALA” is the named title track for “PUREFLOW” pt.1, and the teaser introduces the song through a short scene and dance-focused preview rather than a full music release.
ChosunBiz reported that LE SSERAFIM posted the “PUREFLOW” pt.1 promotion timetable on official social channels and Weverse at midnight on May 6 KST, revealing “BOOMPALA” as the lead track title. The same report described “BOOMPALA” as a newly coined word created for this comeback and noted that “PUREFLOW” is an anagram of “POWERFUL.” 4
StarNews also reported that the group revealed the title track name and promotion timetable through official SNS and Weverse on May 6, adding that “BOOMPALA” is not a dictionary word. That point leaves the title’s meaning officially framed as comeback-specific rather than a standard term with a pre-existing definition. 5
Confirmed “PUREFLOW” pt.1 Promotion Schedule
The confirmed schedule gives the teaser a clear place in the broader rollout. “Just BOOMPALA” arrived after the timetable reveal and before a run of additional content scheduled across mid-May, ending with the album and music video release on May 22.

Billboard Japan additionally reported that “PUREFLOW” pt.1 is scheduled for release in Korea on May 22 and in Japan on June 1. 2 The source material does not specify whether the Japan date refers to a physical release, local distribution timing, or another release format, so the available fact is limited to the reported territory-based schedule.
What Is Known About “BOOMPALA” So Far
The available reports identify “BOOMPALA” as the title track, not a pre-release single or a separate promotional song. They also connect it directly to LE SSERAFIM PUREFLOW rather than to an unrelated project or standalone campaign.
The title’s wording has drawn attention because it is not presented as a standard dictionary term. ChosunBiz described it as a new coined word made for the comeback, while StarNews stated that “BOOMPALA” is not a dictionary word. 4 5 Neither source provides an official full definition, and none of the supplied source records includes a member or agency explanation that assigns a precise meaning to the term.
The wider campaign includes several content formats before release day: a pavilion-themed item, three concept contents, a preview, a highlight medley, and two music video teasers. That structure suggests a planned sequence of visual, conceptual, and audio-related materials, but the sources only confirm the titles and dates of those schedule items, not their full content.
USEN encore also noted a separate chart context for LE SSERAFIM, reporting that “CELEBRATION” charted at No. 170 on Billboard Global Excl. U.S. and No. 2 on World Digital Song Sales for the May 9 chart. 6 That item is not described as part of the “BOOMPALA” teaser itself, but it provides current release-cycle context around the group.
