Actor Park Bo-gum is clenching his fist this time. From a national boxing champion to a strong special team member, he showcases a striking presence.

On the 30th, the production team of JTBC's new Saturday-Sunday drama 'Good Boy' (written by Lee Dae-il, directed by Shim Na-yeon) revealed the script rehearsal scene, which took place in March last year at the JTBC headquarters in Sangam-dong.

Actors Park Bo-gum, Kim So-hyun, Oh Jung-se, Lee Sang-yi, Heo Sung-tae, Tae Won-seok, Seo Hyun-chul, Jung Man-sik, Park Cheol-min, Seo Jeong-yeon, and Seo Jae-hee attended. The scene foreshadowed a comical action investigation drama, oscillating between cheerfulness and tension.

'Good Boy' tells the story of medalists who became police officers through special recruitment. The plot revolves around their struggle against a world rife with immorality and unfair practices, with police badges hanging around their necks instead of medals.

Park Bo-gum plays the role of 'Yoon Dong-joo', a patrolman in the special team. A former boxing gold medalist, he portrays a character with a strong sense of justice. Park Bo-gum leads the atmosphere with his intense gaze and voice.

Kim So-hyun plays the role of 'Ji Han-na', a police sergeant in the special team. A former shooting gold medalist, she exudes a vibrant charm. She is also expected to showcase refreshing action scenes in the drama.

Oh Jung-se plays a customs officer by day and the shadow of evil, 'Min Ju-young', by night. He is the 'bad boy' who opposes 'Good Boy', revealing a chilling evil behind the mask of an ordinary public servant.

Lee Sang-yi takes on the role of 'Kim Jong-hyun', a police sergeant in the special team, a character who embodies both intelligence and physical prowess. He stands out within the team with a performance that balances softness with strength.

Heo Sung-tae plays 'Go Man-sik', the team leader of the special unit, taking charge of the humor with his playful performance. Tae Won-seok joins as 'Shin Jae-hong', a police sergeant in the special team, boasting a heavy presence.

The production team expressed confidence, stating, "The energy of 'Good Boy', filled with laughter, tension, action, and the growing pains of youth, was alive from the set," and "We will deliver catharsis through a story worth more than gold medals, fighting for justice."

'Good Boy' will premiere on May 31st (Saturday) at 10:40 PM.
