Biography

Keonho (건호) was born Kim Keon-ho on February 3, 2007, in South Korea. From an early age, he showed a strong affinity for music, particularly singing.

During his school years, Keonho frequently participated in music-related activities such as school festivals and vocal showcases. Teachers and peers noted his emotional sensitivity and ability to convey feeling through song — a trait that later became his signature strength.

He joined BigHit Music as a trainee after passing a vocal-focused audition, where he underwent intensive training in singing technique, stage control, and performance confidence.

Controversies & Challenges

Outfit Controversy

In October 2025, Keonho (CORTIS) sparked controversy when he wore traditional Korean clothing but intentionally styled it in a sagging way that exposed an excessive amount of his underwear.

Disrespect towards aespa

In September 2025, netizens resurfaced a controversial clip of Keonho (CORTIS), in which he was accused of showing a disrespectful attitude toward senior artists. The video captures Keonho’s reaction when aespa was announced as the winner of their third music show trophy for Rich Man on Show! Music Core, following a very close competition with Haechan (NCT).

As aespa was overseas at the time while Haechan was present at the broadcast, the camera caught Keonho standing behind him. His expression — particularly a pursed-lip gesture — drew attention, leading many netizens to interpret it as a sign of discomfort or dissatisfaction, ultimately sparking controversy.
