The boy group’s lineup includes Martin, James, Juhoon, Seonghyeon, and Keonho, who are being introduced as a young creator crew with no fixed roles, taking part in music, choreography, and visual production themselves. Even before stepping into the spotlight, Martin co-wrote and produced for TXT hits like Deja Vu, Miracle, and Beautiful Strangers, as well as ENHYPEN’s Outside and ILLIT’s Magnetic. James has choreographed for TXT, ENHYPEN, and ILLIT, including their songs Cherish and Tick Tack.
CORTIS will officially debut on August 18, 2025, with their track “What You Want.” An English version featuring Teezo Touchdown will follow on August 22, 2025. Three weeks later, on September 8, fans will get the full EP COLOR OUTSIDE THE LINES. With their creative freedom, industry experience, and the powerhouse backing of BIGHIT MUSIC, CORTIS is stepping into the K-pop world ready to paint far outside the lines.
