I am actor Onsemi. I have convincingly portrayed relatable, true-to-life characters in numerous productions, including the films ＜Secret Class＞, in which I played the center director, and ＜Asking for Directions in Jeonju＞, in which I played Semi, as well as the dramas ＜Countdown to Death＞ (2025), ＜Motel California＞, ＜The Escape of the Seven＞, and ＜Lost＞. Drawing on the fitness and focus developed through boxing, golf, and yoga, I offer dependable performances on set, with quick adaptability and a steady presence.
