They have 1 songs among the most popular in Korea.CORTIS was Big Hit Music's first boy group in over six years after TXT, following a training period that remained largely shrouded in mystery. While rumors circulated under the speculative name "Aloners Association" due to trademark filings and sightings in Los Angeles and Seoul, the final lineup remained private until shortly before their 2025 debut. The group’s identity is centered on a "creator crew" concept, where the members transitioned from traditional trainees to independent artists capable of directing their own visual and musical output. Their debut in August 2025 marked the first idol group launch from Big Hit Music since its corporate restructuring under the HYBE umbrella, positioning them as a bridge between the label's established heritage and a new era of self-produced creative crews.
