Actor Oh Jung-se is stealing the spotlight—and sending chills down viewers' spines—with his intense portrayal of a cold-blooded villain.

🧠 Twisted and Calculated: A New Breed of K-Drama Villain

In JTBC's drama Good Boy (written by Lee Dae-il, directed by Shim Na-yeon), Oh plays Min Joo-young, a customs officer with a terrifying dark side. His unpredictable cruelty and eerie calmness have raised the stakes in the series.

🔫 Cold-Blooded Acts Unfold

In the episodes aired on June 21–22, Min Joo-young is revealed as the shooter who targeted Kyung-il's mother (played by Seo Jung-yeon). Even when confronted by Yoon Dong-joo (Park Bo-gum), he smirked coldly, provoking him with unsettling calm.

Despite being cornered by the Special Crimes Unit, Joo-young remained unfazed—manipulating the team and pulling dangerous strings behind the scenes.

👥 Building His Criminal Empire

Joo-young is gathering criminals like Magwi (Lee Ho-jung), Leo (Go Jun), and Baek-ga (Ahn Se-ho) to tighten his grip on Inseong City, signaling the start of all-out villain domination.

💥 Brutality Behind a Calm Face

When his request was rejected by Section Chief Song (Shin Moon-sung), he resorted to threats. In another shocking moment, he suddenly stabbed Lee Kwang-se (Jung Jae-won) in the thigh during a confrontation—revealing how quickly his calm exterior can spiral into violence.

🎭 A Masterclass in Duality

Oh Jung-se is earning high praise for his layered performance—balancing calculated control with explosive emotion. His ability to portray such terrifying duality has elevated the character from just another antagonist to one of the most compelling villains in recent K-drama.
