BigHit Music's newest boy band, CORTIS, debuted on August 18, 2025, marking the label's first boy group launch in six years since TXT. The five-member group, composed of Martin, James, Juhoon, Seonghyeon, and Keonho, has already garnered significant attention, amassing a large following and achieving impressive chart success. CORTIS's debut is particularly noteworthy due to the considerable influence and guidance they've received from their seniors, BTS.
The group's name, CORTIS, is derived from the phrase "COLOR OUTSIDE THE LINES," symbolizing their mission to break free from established norms and express their originality. BigHit Music has positioned CORTIS as a "young creator crew," emphasizing the members' active participation in songwriting, choreography, and video production. All five members have writing credits on their debut EP, "COLOR OUTSIDE THE LINES," which was released on September 8, 2025.
BTS's influence on CORTIS is evident in various aspects of the group's development and debut. Leader Martin revealed that he was inspired by BTS's leader, RM, and his approach to music and leadership. He shared that RM advised him, "A leader's role is to be there to re-energize the members when they're tired," a sentiment Martin has kept in mind. Martin has also stated that RM is the reason he joined BIGHIT Music. Another member, James, found inspiration in Jimin's stage presence, which fueled his dream of becoming an idol. Furthermore, Juhoon has credited BTS V's "Slow Dancing" as the song he used for his audition. Seonghyeon sang "Mic Drop" while Keonho went with "Dynamite".
Beyond inspiration, BTS has also provided practical advice to CORTIS. Seonghyeon mentioned that BTS wished them well, while TXT offered advice on stage presence and attention to detail. BTS also emphasized the importance of respecting and appreciating the staff, reminding CORTIS that their debut is just the beginning of their journey. Juhoon revealed that BTS advised them that there's no need to be perfect upon debut, but to show improvement and keep evolving. Martin reiterated BTS' advice to "do well by the people that you're working with". James added that everyone, including the staff, is part of CORTIS, emphasizing teamwork.
CORTIS's debut EP, "COLOR OUTSIDE THE LINES," reflects their commitment to originality and boundary-pushing. The lead single, "What You Want," blends elements of 1960s psychedelic rock with hip-hop rhythms. The members were actively involved in the creation of all the tracks, exploring themes of self-discovery and bold self-expression.
The group's early success is a testament to their talent and the strong foundation laid by BigHit Music. CORTIS's debut album sold over 430,000 copies in its first week, ranking No. 1 among rookie debuts this year and No. 4 for first-week sales among debut albums in K-pop history. The album also debuted at No. 15 on the Billboard 200 chart, the second-highest position ever for a debut album by a K-pop act and the highest for a group not formed with members of established acts. Moreover, "GO!" entered Melon's Top 100 chart, a rare feat for rookie boy groups. The group has also gained a substantial presence on social media, with millions of followers on TikTok and Instagram.
CORTIS's debut has been met with enthusiasm from fans and industry observers alike. With their talent, creative vision, and the guidance of their seniors, CORTIS is poised to make a significant impact on the K-pop scene and continue BigHit Music's legacy of creating global acts.
