Juhoon

Juhoon (주훈; Kim Ju-hoon, 김주훈) is one of the youngest members in CORTIS, but his page matters because he did not arrive at BigHit Music as a blank-slate trainee. Before debut, he built camera experience through child-model work and music-video appearances, then translated that comfort in front of the lens into CORTIS's first performance era. The result is a rookie profile that already feels unusually composed for his age.

That background gives Juhoon a slightly different entry point than the standard boy-group maknae story. Publicly documented pre-debut work tied him to commercial and MV sets years before CORTIS launched, while his youth-sports history added the kind of discipline agencies value during the training years. Inside CORTIS, he emerged as part of a member line that does more than execute choreography. He also picked up writing credits early, which matters on a group built around authorship and performance input rather than a purely top-down idol system.

Juhoon's early CORTIS run is already easy to track. He debuted with the group through Color Outside the Lines and helped carry the first release cycle into the 2026 GREENGREEN follow-up. That gives his profile a clean first chapter: pre-debut screen experience, a fast transition into HYBE's rookie pipeline, and immediate participation in the group's opening catalog. If CORTIS keeps leaning into self-driven performance identity, Juhoon looks positioned to grow with it rather than trail behind it.
