CORTIS

CORTIS (코르티스) is the five-member boy group carrying BIGHIT MUSIC into its next post-BTS, post-TXT generation. Martin, James, Juhoon, Seonghyeon, and Keonho debuted in 2025 with a rollout built on crisp performance identity rather than survival-show noise, and that choice paid off fast: Color Outside the Lines gave the group a strong global opening and positioned them as a serious export act from day one. The 2026 cycle turned the debut promise into a wider live and festival story. GREENGREEN, Music Bank in Barcelona, Lollapalooza, and major rookie-award wins all reinforced the same idea: CORTIS is being developed as a touring-first, performance-first group with real international ceiling. Their linked member pages now matter more too, because the group's appeal is not faceless scale. Each member already carries a distinct pre-debut or creative lane inside the bigger BIGHIT system.
