Big Hit Music, the powerhouse behind global sensations like BTS and TOMORROW X TOGETHER, has officially launched its newest boy group — and they’re already making waves.
The group, named CORTIS, just dropped the official music video for their pre-debut track “GO!”, and fans are buzzing over their youthful energy, striking visuals, and fresh creative direction.
This marks Big Hit Music’s first new boy group in six years following the 2019 debut of TXT, making this a highly anticipated move in the K-pop industry.
With expectations riding high, CORTIS appears to be off to a promising start — blending charm, artistic individuality, and modern storytelling in their very first visual release.
Meet CORTIS: The Young Creator Crew
CORTIS — an acronym for “Color Outside The Lines” — embodies the concept of breaking boundaries, redefining creativity, and encouraging authenticity.
The group is described not simply as idol performers, but as a “young creator crew.” This means that members are deeply involved in various aspects of their artistry beyond just singing and dancing.
From songwriting to choreography to videography, the members are said to contribute hands-on in developing their content.
The group consists of five members:
- Martin
- James
- Joohoon
- Sunghyun
- Geonho
All are in their teenage years, adding to the group’s youthful and relatable appeal.
Their fresh perspective and creative ownership are being seen as a major differentiator in a competitive idol market where authenticity and self-expression have become more important than ever to fans.
“GO!” — A Carefree Anthem of Youth
In the official MV for “GO!”, the members are seen enjoying a sun-soaked day in a neighborhood setting — riding bikes, playfully exploring alleyways, and sharing laughter.
The visuals highlight the unfiltered energy of youth, filled with moments of spontaneity, freedom, and genuine friendship.
It’s a nostalgic love letter to summer, painted in warm tones and fluid camera work that gives the video a cinematic yet grounded feel.
The production stays true to the group’s concept — everything feels natural, unscripted, and inviting.
Viewers aren’t just watching a polished idol performance; they’re being invited into a slice of real life through the lens of five dreamers beginning their journey.
Musically, “GO!” leans into upbeat pop with subtle funk and indie influences.
It has a catchy hook, a groovy baseline, and vocals that show promise — especially considering the group’s young age.
The lyrics encourage self-discovery and confidence, aligning with the group’s theme of coloring outside the lines, or living boldly and authentically.
Pre-Debut Strategy & Official Debut Timeline
While “GO!” is a pre-release track, it is part of a carefully designed launch strategy for CORTIS. Big Hit Music is clearly taking a story-driven, momentum-building approach, offering fans glimpses into the group’s identity before the official debut.
CORTIS will debut officially on August 18, starting with their track “What You Want.”
This will be followed by their first mini album (EP), titled “Color Outside The Lines,” which is set to drop on September 8 KST.
The group’s early start with concept-building through creative music videos and pre-release tracks gives fans time to grow attached to each member and their story — a smart move that mirrors Big Hit’s proven strategies with BTS and TXT.
Rising Visual Stars and Early Buzz
Even before their official debut, members of CORTIS have been grabbing attention across Korean forums and international social platforms.
One member in particular — though unnamed in this article — was noted in a viral discussion for being “the most handsome out of all current male idols,” further adding fuel to the growing interest around the group.
Combined with Big Hit’s industry credibility and the group’s own clear talent, CORTIS is shaping up to be one of the most promising rookie debuts of 2025.
Fan and Industry Reactions
The reaction to “GO!” has been overwhelmingly positive. Comments across YouTube, X (formerly Twitter), and TikTok highlight the group’s “authentic vibe,” “natural chemistry,” and “refreshing visuals.”
Many fans also praise the camera work and editing style of the MV, which captures movement and emotion without feeling overly stylized or manufactured.
Industry insiders are watching closely, curious to see how CORTIS will evolve as a self-producing group and whether their “creator crew” model will influence future idol training systems.
A Debut to Watch
With the release of “GO!” and the announcement of their debut EP, CORTIS has officially entered the scene with purpose and personality.
Their blend of youthful energy, creative involvement, and Big Hit’s support system places them in a strong position to become one of the defining rookie acts of the year.
If “GO!” is any indication, CORTIS is not just ready to debut — they’re ready to color outside the lines and redefine what it means to be a K-pop idol in 2025.
