Good Boy (2025) is a Korean action drama produced by JTBC Studios, starring Park Bo Gum in a bold new role. The series follows a group of former Olympic athletes who exchange their medals for police badges in a special recruitment effort to fight systemic corruption.
Yoon Dong Joo (Park Bo Gum), once a national boxing champion, joins the police force through this program. Although skilled in combat, he soon realizes that true justice requires more than physical strength. Alongside other ex-athletes, he tackles crimes that reveal the cracks in Inseong City’s power structure.
However, their greatest challenge is Min Joo Young (Oh Jung Se), a manipulative kingpin who pulls strings from the shadows. As the team closes in, moral boundaries blur, and the fight turns personal. The series explores whether heroes born in the arena can survive the corrupt machinery of the law.
Park Bo Gum, known for his charm and depth, trained rigorously for six months to prepare for the role. His physical transformation and layered performance are already drawing attention. With intense fight choreography, emotional stakes, and a gripping storyline, Good Boy balances adrenaline with soul.
Scheduled to premiere on May 31, 2025, the 16-episode series has sparked high anticipation. Early teasers hint at a tightly paced narrative, culminating in Yoon Dong Joo’s chilling line: “Once you start, there’s no turning back. It’s time to pull the trigger and break the silence.
