JTBC has released striking new posters for its upcoming drama 'Good Boy,' giving fans a first glimpse at the determined cast. This comic action series tells the story of five former national athletes who join the police force through a special recruitment program. Each character brings their own strengths to the table as they take on a world full of corruption, deception and injustice.
Park Bo Gum plays Yoon Dong Joo, a former boxing gold medalist who was demoted after a series of unfortunate incidents. He starts over from the bottom, carrying with him a deep sense of pride and an unwavering determination. His poster, with blood and sweat on his face and hands wrapped in bandages, hints at the intense battles he’s faced both in and out of the ring. Park described Yoon Dong Joo as someone who is driven by a burning sense of justice and never backs down, no matter the situation.
Kim So Hyun portrays Ji Han Na, a former Olympic shooting champion and current Special Forces corporal. Known once as the "Goddess of Shooting," she appears cool and calculated as she focuses her aim. Though her expression is cold, her character is shaped by real-world experience and holds a steady inner fire. Kim explained that Ji Han Na is like a radar who remains clear-headed but is fueled by deep passion. She doesn't act on emotion but instead carefully assesses each situation and makes thoughtful decisions.
Lee Sang Yi takes on the role of Kim Jong Hyun, a fencing silver medalist turned Special Forces inspector. His sharp mind and quick reflexes make him a skilled investigator. Dressed sharply with an intense gaze, he reflects precision and logic. Lee compared him to a pair of cracked glasses that he can’t bring himself to throw away because they fit him best. Even with flaws, Kim Jong Hyun remains firmly committed to his path.
Heo Sung Tae plays Go Man Sik, a former wrestler who now leads the Special Forces team. Time and experience have turned him into a calm and dependable leader who prefers patience over brute strength. His worn detective jacket suits him more than a wrestling singlet. Heo described Go Man Sik as a father figure who might be anxious at times but always moves forward for the sake of his team and loved ones. His character brings everyone together with a quiet strength that blends seamlessly with others.
Tae Won Suk brings surprising charm to the role of Shin Jae Hong, a former discus thrower with a massive physique and a warm, playful smile. At first, he believes that strength alone is justice, but over time, he evolves into someone who balances his duties as a detective with the responsibility of supporting his family. Tae compared him to a pine tree, always steady and loyal, staying with his team even when he seems to take a step back. His ability to rise to the occasion when it matters most makes his role one to watch.
The character of Min Joo Young, played by Oh Jung Se, stands in stark contrast to the rest. Unlike the others, he hides a sinister side beneath the appearance of an ordinary customs officer. His dark poster lacks a sports symbol and instead features an unsettling "X" that suggests something far more dangerous.
While the five officers face one direction, Min Joo Young looks the other way, visually separating him from the group. Oh Jung Se shared that he wanted to portray the kind of monster that hides among us, reminding viewers of the importance of recognizing and confronting evil.
'Good Boy' is set to premiere on May 31 at 10:40 p.m. KST. With its mix of action, emotion and character depth, the drama promises an exciting ride from start to finish.
