LE SSERAFIM released their new song and music video for "BOOMPALA" on May 22 (KST), marking their return following Kim Chaewon's recent health break announced earlier this month.

The release faced divided reactions from fans, with particular criticism directed at youngest member Eunchae's vocal performance. Social media quickly filled with comments about her vocals being off-key, with some comparing her tone unfavorably to other K-pop artists. Groupmate Sakura also drew vocal criticism from some listeners.

This comes after the group already weathered backlash over the music video teaser in the lead-up to the full release. The comeback timing coincides with Chaewon stepping back from activities; SOURCE MUSIC confirmed on May 19 that she received medical attention and requires recovery time, though specifics weren't disclosed.

The "BOOMPALA" release represents LE SSERAFIM's latest challenge in a year that's included multiple controversies and personnel changes. While the song itself sparked mixed opinions on its production and concept, much of the online discussion has centered on performance critiques rather than the track's overall reception.

It remains to be seen how the group will address the vocal feedback or whether they'll adjust their approach moving forward. For now, LE SSERAFIM is moving ahead with promotions for the new release while Chaewon focuses on her recovery.
