Park Ji Hoon has redefined his career on his own terms. Once known for his signature wink and bright image as a former Wanna One member, he has fully stepped into serious acting in 2026. Two major roles define that shift: the brilliant but fierce Yeon Si Eun in Weak Hero Class 1 & 2, and the tragic King Danjong in The King’s Warden.
Weak Hero was the turning point that made the industry see him differently. The King’s Warden goes even further, confirming his long-term credibility as an actor. One role shows a quiet, simmering rage. The other carries the sorrow of a fallen king. Together, they complete Park Ji Hoon’s transformation as an actor.
The King’s Warden
In The King’s Warden, Park Ji Hoon plays Lee Hong Wi, the deposed King Danjong—a role usually shown as a helpless child in historical dramas. Director Jang Hang Jun takes a different approach and showsthe king’s life in exile.
Park’s performance stands out for what he doesn’t do. Early on, his character feels like a ghost, crushed by powerlessness. He doesn’t cry or scream. Park instead shows his despair through slumped shoulders, a distant gaze and a thin, skeletal frame—after losing 33 pounds for the role. He doesn’t just act despair; he lives it.
The heart of the film is his bond with the village chief, played by Yoo Hai Jin. Park slowly transforms from a broken king to a man learning to live again. The transformation is subtle—small details, like the way he breathes or the light returning to his eyes, reveal his growth. By the time he faces his ultimate fate, he does so with calm dignity, turning a tragic figure into a heroic one.
Weak Hero Class 1 and 2
If the king represents sorrow, Yeon Si Eun represents a silent, turbulent fire. In the Weak Hero series, Park plays a top student who uses physics and raw intellect to dismantle bullies.
Before this series, Park was largely seen as a pretty idol-turned-actor. Yeon Si Eun shattered that mold. He is a voluntary outsider whose silence hides a cocktail of anxiety and obsession. Park’s brilliance here is in his restraint. He modulates Si Eun’s inner rage through his gaze and his breathing. Every lip-twitch and cold stare is a strategic move.
By Season 2, Si Eun has evolved from a victim into a survivor, carrying the heavy trauma of his past failures. Park’s acting becomes even more robust here, showing a character who has internalized his anger and learned the burden of responsibility.

One thing connects these two very different roles: Park Ji Hoon’s eyes. His gaze is his strongest tool. Whether facing bullies in a high school hallway or staring into the lonely exile of a fallen king, his eyes carry a deep sadness that speaks louder than any words.
In a world where many actors rely on big, dramatic gestures, Park shows the power of quiet acting. Through the boy’s anger and the king’s sorrow, he proves he’s no longer just an idol—he’s a serious force in film and TV.
