Five-member rookie group CORTIS, who debuted in August last year, is creating a sensation on domestic and international charts with distinctive lyrics, rough sound, and free-spirited choreography. The term '영크크 (Young Creator Crew)' featured in their hit songs has become a neologism representing people with youthful sensibilities. CORTIS participates directly in all aspects of their music including songs, choreography, music videos, and styling. Unlike existing K-pop groups, they don't establish a specific world concept and instead deliver light everyday stories in a 'less serious' manner. Songs like 'Teppanyaki,' 'Acai,' and 'Red Red' are gaining massive popularity with their meaningless yet captivating lyrics. Music critics analyze that CORTIS strategically captures modern social media consumption patterns and creates synergy with meme culture. The group has charted on Billboard's album chart for five consecutive weeks, and attention is focused on how their unique musical style will influence future K-pop trends.
