The story so far
Before becoming a trainee, Keonho spent five years swimming competitively. He specialised in backstroke and raced short distances, developing stamina and a habit of measuring progress against himself.
Making music with CORTIS brought a different challenge: turning five perspectives into one shared vision. He helped plan and storyboard music videos, using sketches and references to communicate camera movements.
He describes being drawn to the stage and the possibility of making audiences smile. Vintage shopping and visual experiments are other ways he explores his own creative identity.
In his own words
