Pyo Ji-hoon

Pyo Ji-hoon (표지훈), better known to many viewers as P.O, has turned what could have stayed idol side-quest casting into a real second lane. He debuted through Block B, but his screen work now carries its own weight, especially in the years leading into Netflix's Teach You a Lesson. That series places him next to Lee Sung-min, Jin Ki Joo, and Kim Moo-yul in one of 2026's most watched WEBTOON adaptations.

What makes Pyo interesting as an actor is that he does not try to erase the entertainer in him. Variety made him familiar, but dramas like Encounter, Mouse, and Good Partner proved he could work inside bigger ensemble rhythms without feeling like stunt casting. He has a natural looseness on camera that helps when a character needs warmth or unpredictability, and that quality becomes useful in projects that would otherwise tilt too grim.

Teach You a Lesson arrives at a good time for him. He is no longer being introduced as a surprising idol-actor crossover. He is being cast as part of the selling point. With Block B still anchoring his public identity and acting credits stacking more steadily, Pyo now reads less like a novelty and more like a durable multi-platform Korean entertainer with real range.
