A recent appearance by girl group NMIXX on SBS’s Youngstreet — hosted by Red Velvet’s Wendy — has set off a firestorm online, after Wendy’s reaction to a powerful live performance by Lily drew mixed responses from fans.
During the broadcast, part of NMIXX’s promotions for their latest album Fe3O4: Forward and its title track “Know About Me,” Lily impressed listeners by performing Red Velvet’s “RBB (Really Bad Boy), a song widely regarded as one of the most vocally challenging in K-Pop. Known for her soaring range and smooth tone, Lily executed the song’s demanding high notes with apparent ease — prompting a wave of praise from fans and vocal enthusiasts alike.
However, a viral clip circulating on X — which has amassed over 3.3 million views — claims Wendy appeared visibly “pissed” or unimpressed by Lily’s rendition. The short moment, interpreted by some as subtle side-eye or awkward silence, has fueled a wave of speculation and divided reactions among fans.
Some viewers defended Wendy, saying the moment was blown out of proportion or misread entirely. Others felt her reaction lacked the warmth and encouragement typically expected from senior idols during such appearances — especially considering the difficulty of the song and Lily’s strong execution.
The post sparked intense debate between Red Velvet’s ReVeluvs and NMIXX’s NSWERs, with many calling for fans to focus on the talent and positive energy Lily brought to the show instead of stirring unnecessary fanwars.
As of now, neither Wendy nor SBS has commented on the controversy, and many fans are urging calm — reminding others that moments can easily be misinterpreted, especially in the fast-moving world of social media.
