Keonho

Keonho (건호; An Keon-ho, 안건호) is the youngest member of CORTIS, but his profile reads older than his age because of the way discipline shows up in his story. Before music became the focus, he spent years in competitive swimming, a background that shaped the quiet endurance and repetition-heavy work ethic agencies value during training. That sports foundation became one of the clearest framing points once he entered BigHit Music.

Inside CORTIS, Keonho has been presented as more than a symbolic maknae. He arrived in the group's opening cycle with writing and performance contribution already attached to the narrative, helping reinforce the idea that CORTIS is not being built as a purely passive rookie act. For a member born in 2009, that matters. It suggests the company sees him as part of the group's long creative runway, not just its youngest visual reference point.

His first chapter is already cleanly defined. Keonho debuted through Color Outside the Lines, stayed visible through What You Want, and then moved into the 2026 GREENGREEN cycle as CORTIS widened its catalog. The combination of athlete-to-trainee discipline, maknae positioning, and early credit participation gives him one of the stronger development arcs in the lineup. If CORTIS keeps expanding its author-driven identity, Keonho looks built for steady long-term growth rather than a short rookie spike.
