Why LE SSERAFIM Fans Are Furious About The Group’s Latest Performance Video
LE SSERAFIM‘s latest Studio Choom performance video is drawing unexpected backlash—not because of the members, but because of an alleged male trainee’s appearance.

Following the release of the group’s Studio Choom performance for their latest title track “BOOMPALA,” fans quickly began discussing the ending section of the video, where several backup dancers appear, and one male dancer is given a noticeable solo moment.
Some fans have since alleged that the dancer is not simply a performer, but a male trainee under Source Music. The speculation immediately sparked frustration among LE SSERAFIM fans, many of whom felt that the group’s long-awaited comeback performance was being used to promote someone else.
One viral reaction read, “They’re saying he’s a Source male trainee. LE SSERAFIM is basically being used as backup right now to promote him. I’m so dumbfounded.”

Another fan pointed out that the performance video was especially significant because LE SSERAFIM recently returned with their second full-length album after three years.
그니까 3년만에 정규 2집으로 돌아온 르세라핌이,
그것도 유일할 5인안무 퍼포영상에,
쏘스 남연생 홍보하기 위해 10초동안
원샷 잡아주며 우리를 들러리로 사용했다?
ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ

So LE SSERAFIM came back with their second full album after three years, and in what may be their only five-member choreography performance video, they used us as extras to promote a Source male trainee by giving him a 10-second solo shot?

Others criticized the creative decision itself, questioning why the ending dance break focused on a male dancer instead of the members.
“I don’t understand what strange idea this is, both on music shows and Studio Choom, where a bunch of dancers rush out at the end and they give a dance break to some random male dancer,” one fan wrote.
근데 음방에서도 그렇고 스춤에서도 그렇고 마지막에 댄서들 우르르 몰려나와서 이상한 남댄서한테 댄브주는건 무슨 괴상한 아이디어인지 모르겠음 당장 갖다 치웠으면
르세라핌은 연말무대나 콘서트빼고 댄서 필요 없다고요— 김김이 (@doraei22) May 22, 2026
Please get rid of it immediately. LE SSERAFIM doesn’t need dancers except for year-end stages or concerts.

Another reaction similarly asked, “Why is LE SSERAFIM’s full album title track being used to hype up some male trainee?”
르세라핌 정규 타이틀곡을 왜 남자 잼민이 연습생 하입시켜주는 용도로 쓰는 겁니카 왜….ㅠㅠㅠㅠㅠ

Many fans were especially upset by the possibility that the moment could later be used as pre-debut promotion.
그냥 벌써 헐 그때 붐팔라 무대에 섰던 그 친구가 데뷔를? 이러면서 바이럴할거 생각하니까 너무 열받음… 왜 르세라핌이 정규 타이틀곡 무대에서 모르는 남자 원샷 받을동안 뒤에 있어야 하죠?? 왜 그러는거야.. 화내기 싫어 붐팔라 느끼고 예뻐해줄 시간도 부족한데 자꾸 뭐하는거냐고

I’m already mad thinking about how they’ll later go viral with, ‘That guy from the BOOMPALA stage is debuting?’ Why does LE SSERAFIM have to stand in the back while some unknown guy gets a solo shot during their full album title track stage? I don’t want to be mad about this. Like there isn’t even enough time for me to enjoy BOOMPALA. But then what sh*t is this?
— Fan
Another fan added, “What was that male dancer at the ending? I don’t know if they’re planning to market him later as the male trainee who appeared on LE SSERAFIM’s stage or if he’s actually just a dancer, but please stop with these tone-deaf decisions.”
그리고 마지막 엔딩 댄서 뭐지요? 나중에 르세라핌 무대에 섰던 남자 연습생으로 바이럴 돌리실 생각인지 진짜 댄서인지는 모르겠지만 감다뒤 행보 이제 그만둡시다 boompala🧘♀️

As of now, the identity of the dancer has not been officially confirmed, and Source Music has not publicly addressed the backlash. However, the reaction shows that many fans feel strongly that LE SSERAFIM’s comeback stages should keep the focus on the members, especially during a major full-album promotion cycle.
