LE SSERAFIM Horror Teasers Introduce a Darker PUREFLOW Story Ahead of May Release

LE SSERAFIM’s horror teaser rollout for ‘PUREFLOW’ pt.1 moved into sharper focus with a new video and concept photo set released at midnight KST on May 12. The new material presents a horror-fantasy narrative in which each member transforms into a monster as night falls, extending the fear-centered themes already attached to the group’s second studio album campaign.¹

The teaser update arrives ten days before ‘PUREFLOW’ pt.1 is scheduled for release on May 22 at 1 PM KST. SOURCE MUSIC previously announced the album through Weverse as LE SSERAFIM’s second studio album, describing it as the opening of a new chapter built around change and growth that come from acknowledging and confronting fear.²

LE SSERAFIM Horror Teasers Frame ‘PUREFLOW’ pt.1 Through Nightfall

The May 12 teaser set gives the album campaign its most explicitly horror-driven imagery so far. allkpop reported that the release included both a video and concept photos, with the story built around a nightfall transformation motif. In that setup, the members are shown within a horror-fantasy premise rather than a standard performance or portrait-based teaser format.¹

That concept also fits the broader language SOURCE MUSIC used when announcing ‘PUREFLOW’ pt.1. The official Weverse notice framed the album around facing fear, change, and growth, while also confirming that ‘CELEBRATION’ would arrive earlier on April 24 at 1 PM KST and that pre-orders would begin on April 13 at 11 AM KST.²

The title itself has been positioned as part of the comeback’s conceptual structure. ChosunBiz, carrying OSEN’s report, said ‘PUREFLOW’ is an anagram of ‘POWERFUL’, while the title track ‘BOOMPALA’ was introduced as a newly created word for the comeback.³ The combination of an anagram-based album title, a coined title-track name, and a horror-fantasy teaser places the LE SSERAFIM PUREFLOW campaign in a tightly branded visual and linguistic framework.

Campaign Builds From ‘We walkin’ here’ to ‘BOOMPALA Pavilion’

The horror teaser follows earlier promotional content that had already introduced fear as a central narrative element. Sports Kyunghyang reported that LE SSERAFIM posted the ”PUREFLOW’ pt.1′ trailer ‘We walkin’ here’ on the HYBE Labels YouTube channel and Source Music official social media on April 17. The trailer used the theme ‘Chosen Family’ and depicted the members supporting Kazuha as she faced a monster representing anxiety and fear.⁴

That earlier trailer was directed by Kim Hansol, according to the same report, and marked an acting-focused promotional step for the five members. It also placed ‘CELEBRATION’ ahead of the album schedule, with the song set for April 24 before the full album release on May 22.⁴

The campaign then expanded through a promotional website. StarNews reported that LE SSERAFIM opened the ‘BOOMPALA Pavilion’ promotional website at midnight on May 11, one day before the new horror teaser set. The site presents the album concept through water imagery, a team logo on the surface, member-based ‘meditation guide’ content, and a message-writing feature.⁵

StarNews also reported that the promotional site revealed an 11-song tracklist including ‘CELEBRATION’ and ‘BOOMPALA’.⁵ The title track name had already been disclosed on May 6 through official SNS and Weverse, alongside a promotion timetable for ”PUREFLOW’ pt.1′. That timetable included content titles such as ‘Just BOOMPALA’, ‘BOOMPALA Pavilion’, ‘BIRCH SCAR’, ‘YUSU LILY’, ‘PEONY ROOM’, a highlight medley, and two music video teasers before the May 22 release.³

Together, the documented rollout shows a campaign moving through several connected stages: an album announcement centered on fear and growth, an early trailer using a monster as a symbol of anxiety, a promotional website built around ‘BOOMPALA’, and now a horror-fantasy teaser set that gives the concept a more direct nightfall narrative.

Release Timing and Confirmed Album Details

The confirmed release date remains May 22 at 1 PM KST for ”PUREFLOW’ pt.1′. That timing appears across the official Weverse announcement and multiple reports on the album campaign, including the May 12 teaser report and the April 17 trailer coverage.¹⁴²

The album is formally identified by SOURCE MUSIC as LE SSERAFIM’s second studio album. The official discography page uses the styling ”PUREFLOW’ pt.1′, while the promotional reporting surrounding the project connects the album to ‘CELEBRATION’, ‘BOOMPALA’, and a set of visual concepts including ‘BIRCH SCAR’.⁶⁵

LE SSERAFIM PUREFLOW horror fantasy teaser concept

The May 12 horror teaser is therefore not an isolated visual change but part of a campaign that has repeatedly returned to fear, transformation, and confrontation as organizing ideas. With the album release set for May 22 at 1 PM KST, LE SSERAFIM’s latest ‘PUREFLOW’ pt.1 teasers place the comeback’s darker story line at the center of its final pre-release stretch.
