Before choosing to join BigHit Music, he was a competitive swimmer, holding the top rank in his age group and continuing to swim competitively until the sixth grade — a level of early athletic discipline that fans often point to as part of the foundation for his focus and work ethic as a performer.
At his Doljanchi, the traditional Korean first-birthday ceremony where a child is presented with several objects to “choose” from as a playful prediction of their future, Keonho reportedly chose rice — a small but fondly repeated piece of trivia among fans.
Career Highlights
Debut and CORTIS’s Formation Keonho officially debuted as the maknae of CORTIS, BigHit Music’s third group after BTS and Tomorrow X Together, on August 18, 2025, with the digital single “What You Want,” following the pre-release single “GO!” released a week earlier.
As the group’s youngest member, his fresh energy and creative involvement quickly made him a key part of CORTIS’s overall identity.
A Songwriter and Video Producer Keonho held writing and composing credits on four of the five tracks on CORTIS’s debut EP, Color Outside the Lines — “GO!,” “What You Want,” “FaSHioN,” and “JoyRide” — and also participated in choreographing “GO!”
Behind the scenes, he was especially active in video production, personally helping film parts of the “GO!” music video using phones and experimenting with Reels-style effects, including 360-degree camera shots — hands-on contributions that reflect CORTIS’s broader identity as a group of genuine young creators rather than performers alone.
Continued Creative Momentum As 2025 turned into 2026, Keonho kept up his creative pace alongside the rest of CORTIS.
The group’s second EP, GreenGreen, released May 4, 2026, saw Keonho contributing writing and composing credits on “TNT,” “REDRED,” “ACAI,” “YOUNGCREATORCREW,” and “Wassup” — continuing the same level of hands-on musical involvement he’d shown from the group’s very first release.
Rapid Global Rise CORTIS’s rise since debut has been remarkably swift. GreenGreen charted across numerous international markets, including a peak of Number 2 on Japan’s Oricon Albums chart and top-10 placements in Belgium, France, and Austria.
In 2026, CORTIS also headlined NBA All-Star Game weekend, a historic first for a K-pop group, and embarked on a sold-out world tour.
Personality and Public Image
Keonho has admitted that he finds the group’s older members “weird, but in a good way” — a lighthearted comment that reflects both his youthful perspective and the genuine warmth of his dynamic with his bandmates.
He prefers the winter season, largely because he loves the holidays, and has a particular fondness for French fries and salted caramel ice cream.
Despite being the group’s youngest member, his active role in both songwriting and video production has earned him respect within CORTIS as a genuine creative contributor rather than simply the “baby” of the group.
