[OSENWORLD] Rookie boy group CORTIS held their first solo showcase just three weeks after their debut, delivering an emotional night for fans worldwide.
On September 8, the group staged the “CORTIS 1st EP [COLOR OUTSIDE THE LINES] Release Party” at Korea University’s Hwajeong Gymnasium in Seoul. The event was livestreamed via Weverse, HYBE Labels’ official YouTube channel, and TikTok, reaching fans in 190 countries in real time.
The night opened with the first-ever live performance of follow-up track “FaSHioN,” with the five members radiating high energy and commanding the stage. After a fiery rendition of “GO!,” the group told the crowd: “Since this is our very first solo performance after debut, we’re even happier. Please enjoy tonight like it’s a real party.”


For title track “What You Want,” CORTIS pulled out 31 treadmills, delivering a performance on a scale rarely seen even on televised music shows. Moving between the main and extended stages, the members hyped up the venue with free-spirited choreography while fans responded with deafening chants. The setlist also included “JoyRide” and “Lullaby,” both unveiled for the first time.
Between stages, the group revealed self-produced content, including a special video for “GO!,” a playful skit for “What You Want,” and the premiere of the official “Lullaby” music video—underscoring their identity as a “young creative crew.” An unplanned encore capped off the night, further cementing the bond with fans.
As the show drew to a close, members were moved to tears. “We’ve come all this way to witness this beautiful moment. Standing here feels like such a blessing. Thank you sincerely,” they said. “It’s only been three weeks since our debut. We want to share this long journey with you, our fans.”

CORTIS, launched under HYBE’s BigHit Music—its first new boy group in six years—will drop a conceptual performance film for “FaSHioN” on September 9, followed by their official comeback stages starting with Mnet’s M Countdown on September 11.
