CORTIS, a trending K-pop group, took the stage at a street cheering event for the South Korean national football team's 2026 FIFA World Cup qualifier, adding to the excitement at Gwanghwamun Square.
According to their agency BIGHIT MUSIC on Wednesday, CORTIS (Martin, James, Juhoon, Seonghyeon, Keonho) attended the "KT 2026 Cheer: All of Us Together. For Victory" event held that morning at Gwanghwamun Square in Seoul. The event was co-hosted by KT, the Korea Football Association, and the Red Devils ahead of the first World Cup qualifier between South Korea and the Czech Republic. CORTIS was the only K-pop act to perform, lifting the mood on site.
The members appeared on stage performing the cheer song "For Victory" alongside rock band TRANSFIXION. Dressed in red uniforms reminiscent of the Red Devils and wearing face paint, they joined citizens in wishing the national team success. They then delivered the message, "Show cheering as hot as today's sunshine," and led the crowd in singing the children's song "All of Us Together," uniting the cheering passion across the square.
The stage featured a total of four songs, including their debut song "What You Want," along with "GO!", "REDRED," and "YOUNGCREATORCREW." As the energetic performances unfolded, the audience responded with sing-alongs and cheers, and created a festive atmosphere by following along to the "flappy-ear dance," the signature choreography of "REDRED."
The cheering continued off stage as well. CORTIS released short-form content on its official social media featuring lyrics of "REDRED" rewritten as a football cheer version, drawing attention. With the witty lyrics, "Our team our team go red-red, advance to the round of 16 green green," they cheered for the national team's success. As KT's exclusive models, they also took part in the brand campaign video, adding to the street cheering fervor.
Meanwhile, CORTIS has recently established itself as a representative group for the "Zalpha generation," encompassing both Generation Z and Generation Alpha, through promotions for its second EP "GREENGREEN." The track "YOUNGCREATORCREW" gave rise to the buzzword "Young-keu-keu," its abbreviated form, emerging as a cultural code for the younger generation. The second EP surpassed 2.31 million in first-week sales and reached No. 3 on the U.S. Billboard's main album chart "Billboard 200," marking its best-ever result. In addition, all seven North American shows of its first solo tour "2026 CORTIS TOUR" sold out, proving its global popularity.
