Actor Oh Jung-se is turning heads with his chilling performance in JTBC's weekend drama Good Boy. Taking on a villainous role, he dives deep into the character of Min Joo-young, a calm yet calculated criminal mastermind.

🎭 A New Side of Oh Jung-se

Currently starring in Good Boy, Oh Jung-se plays Min Joo-young—an antagonist who subtly dominates Inseong City through organized crime. Opposite Park Bo-gum's lead character, he brings a heavy presence to the screen with a calm voice and a piercing gaze.

In a YouTube video released on June 27, the actor shared personal reflections on the project and the meticulous process behind building his character. From tone to body language, he crafted a chillingly realistic villain.

🧠 Building a Believable Villain

Oh revealed that what drew him to Good Boy was its core message: justice for those who want to live kindly. He was also fascinated by the distinct charm of each character.

He explained, "I focused on how Min Joo-young could become the ultimate trigger that sets the special team into action." To do this, he analyzed every line of dialogue, embodying the role with both depth and nuance.

For inspiration, he tapped into the nonchalant yet terrifying personas he saw on TV as a child. A key line—"I don't quite remember"—was his creative addition, further painting Min Joo-young as a quietly sinister figure.

🧩 A Role Meant to Provoke Thought

"I hope this drama makes viewers ask, 'What kind of monster do I imagine when I hear that word?'" Oh shared. "If it can leave behind even a small moment of reflection, it will have been meaningful."

Viewers agree. With his deceptively ordinary face and disturbingly calm demeanor, Oh Jung-se's character is being hailed as one of the most terrifying villains of the year. Each episode peels back another layer, revealing the twisted core within.

📺 Good Boy airs every Saturday and Sunday at 10:30 PM (KST) on JTBC.
