K-pop girl group KISS OF LIFE once again became one of the biggest talking points at WATERBOMB Seoul 2026, delivering a high-energy performance that included a surprise preview of their upcoming single “SWEAT” and an unexpected onstage kiss that quickly went viral online.

KISS OF LIFE WATERBOMB 2026

The group took the stage on July 24 at the outdoor Global Stage at KINTEX in Ilsan during the opening day of the annual summer music festival. Returning for their third consecutive WATERBOMB appearance, KISS OF LIFE showcased their signature confidence and charismatic stage presence with a setlist packed with fan favorites.

Opening with “Who Is She,” the quartet continued with hit songs including “Midas Touch,” “Igloo,” “Lips Hips Kiss,” “k bye,” “Lucky,” and “Tell Me,” drawing enthusiastic cheers from thousands of festivalgoers.

One of the event’s biggest highlights came when the group performed part of their upcoming third single, “SWEAT,” ahead of its official release. The surprise stage gave fans an early look at the comeback, which is scheduled for August 4.

As expected from WATERBOMB veterans, the members embraced the festival’s bold atmosphere with eye-catching stage outfits featuring bodysuits and hot pants. Their energetic choreography and confident performance further cemented their reputation as one of the event’s standout acts.

However, the performance generated even more buzz after an unexpected moment involving members Natty and Belle. During one of the songs, the two briefly leaned toward each other and appeared to share a kiss. The scene was captured from multiple audience angles and rapidly spread across social media.

Following the concert, fans who attended the event said the members addressed the incident, explaining that it had not been planned. According to attendees, Belle said she had simply misjudged the distance between them, resulting in the accidental contact.

The explanation, however, did little to stop the online discussion. Many fans reacted with amusement, celebrating the moment and joking that it perfectly matched the group’s name. Others praised the members for maintaining their composure and continuing the performance without interruption.

Not everyone viewed the incident positively. Some social media users criticized the moment, accusing the group of using “queerbaiting” to attract attention or regain public interest following previous controversies.

At the same time, others pushed back against those accusations, arguing that it is inappropriate to assign motives or speculate about the sexuality of real people based on a brief onstage interaction. Many defended the members, saying there was no evidence that the moment had been intentional or designed as a publicity stunt.

Despite the differing opinions, KISS OF LIFE remained one of the most talked-about acts of the festival. Between their powerful live performances, the first glimpse of “SWEAT,” and the viral moment that dominated social media, the group successfully captured the spotlight at WATERBOMB Seoul 2026 as anticipation continues to build for their upcoming comeback.
