5 Things About CORTIS, BIGHIT Music’s New K-pop Boy Group

1. Who is CORTIS? The Young Creators
@cortis_bighit hello we are CORTIS and our name sounds like… #CORTIS #코르티스 ♬ 오리지널 사운드 – CORTIS
CORTIS is the 5th-gen K-pop boy group of BIGHIT Music. The letters are taken randomly from “Color Outside the Lines.” This hints at the group’s intention to break away from traditional K-pop molds and create their own artistic identity.
CORTIS is a five-member K-pop boy group of talented teenagers, which consists of Martin, James, Juhoon, Seonghyeon, and Keonho.
- Martin (Leader) — March 20, 2008, 🇰🇷🇨🇦. Genius producer.
- James — October 14, 2005, 🇨🇳🇹🇭. A former member of Trainee A). Rapper and main lyricist.
- Juhoon — January 3, 2008, 🇰🇷. Skilled choreographer.
- Seonghyeon — January 13, 2009, 🇰🇷. Vocal and Visual.
- Keonho — February 14, 2009, 🇰🇷. Creative director.
Their average age highlights a new generation of idols born mostly around 2008 and 2009, emphasizing youth and creativity.
BIGHIT Music describes them as a “young creators’ crew.” This is because each member brings unique skills across multiple disciplines beyond performance. They are involved in their creative process, including songwriting, choreography, and visual production.
2. Self-Produced Debut: Music, Choreography, Visuals
Unlike many rookie K-pop groups who debut with music and concept primarily by producers, CORTIS members are actively involved in composing their debut tracks, choreographing their performance, and shaping their visual identity.
This hands-on approach makes them a true “creator crew.” It gives them more creative freedom to produce an authentic and original work right from their debut.
3. BIGHIT Music’s Pivotal Moment & New Group with Bold Mission

The debut of CORTIS is a pivotal moment for BigHit Music. It’s the label’s first new boy group in six years, and it’s expanding its artist family beyond BTS and TXT. Because of this, expectations are very high.
CORTIS brings fresh ideas to the competitive 5th generation of idols. The group is also expected to show a new creative direction where members help produce their own music and share their own stories. Both industry experts and fans see CORTIS as an up-and-coming act. With their youthful energy and creative freedom, they could truly change the idol scene.
4. Experienced Creators with Proven Track Records
Though CORTIS will make a debut as a new group, some of the members have already proven their skills in producing music and dance choreography. James and Martin have credits for producing some HYBE artists’ tracks like TXT’s “Miracle,” “Deja Vu,” and ILLIT’s “Magnetic.” Martin also contributed to LE SSERAFIM’s “Pierrot” and ENHYPEN’s “Outside.” And James is recognized for choreographing for TXT.
These experiences equip CORTIS with a strong foundation as artists and creators. This also becomes a signal of a shift towards artist-driven creativity in K-pop.
5. Unique and Engaging Pre-Debut Events
To build excitement for their debut, BIGHIT Music is hosting a 24-hour worldwide premiere livestream on August 10, 2025, on HYBE LABELS’ YouTube channel. It will offer an exclusive behind-the-scenes footage, debut hints and teaser content, glimpses into the group’s concept and personalities, and real-time fan Q&A sessions with all members.
