Bloody → pure constable..Good Boy Park Bo-gum, Extreme Transformation



Park Bo-gum, Kim So-hyun, Lee Sang-i, Heo Sung-tae, and Tae Won-seok will visit the small screen on May 31.

JTBC's new Saturday-Sunday drama 'Good Boy' (played by Lee Dae-il, directed by Shim Na-yeon) unveiled for the first time a still cut of 'Before and After' which became a special police detective for the national team.

First, Yoon Dong-ju (Park Bo-gum) is a boxer who was called a national hero by winning gold medals in the past. Having enjoyed the world's No. 1 glory by biting the gold medal, he becomes a police officer with a special national team. Although he was expected to have an animal sense and natural athleticism, his police life is not smooth. He is a young police officer who was demoted to a constable after causing a series of accidents. Yun Dong-ju, who is so brave and bright, seems to be a simple character who believes in just one fist and goes wild, but in his heart, a sense of justice and warm heart lives and breathes.




Ji Han-na (Kim So-hyun), who was cooler and more outspoken than anyone else in front of the target, swept various shooting competitions while listening to geniuses from middle school. In the image of pulling the trigger with a sharp look and an unshakable posture that penetrates the target, she is 'Shooting Goddess' itself. Now he is walking his second life as a police officer, but unlike his desire to go to the scene, he is only mobilized to promote the image of the National Police Agency under the title of an international competition star. That's how she grabs the gun in front of the camera, not the culprit today.

Kim Jong-hyun (Lee Sang-i) is a fencing silver medalist-turned-police officer. With his brilliant brain and sharp movements, he is a cool-headed elite who puts reason and logic first. When he was a member of the national team in a still cut, he showed strong concentration by playing in a meticulous calculation while wearing a fencing suit and holding a sword. Currently, he wears a suit and works in the inspection and investigation community, adhering to the FM style that values order and balance. Even in the coolness of the principleist, he has a subtle humanity, and behind his rational attitude lies a lack from the past.

Ko Man-sik (Heo Seong-tae) was a man of fighting spirit who threw his whole body on the wrestling mat and overpowered his opponent to win the bronze medal. His sweaty face and determined eyes contain the desperation and fierceness of the moment he won the medal. Now, he has become a detective who has become a veteran of enduring reality with his know-how in wrestling. The fact that he was able to rise to the position of lieutenant is the result of more than a decade of hard work, catering to bosses with a business mind.




Shin Jae-hong (Tae Won-seok), who threw the disc with his natural steel shoulder and strength. Leaving behind the power that once cut through the sky with the perfect harmony of power and skill, he becomes a police officer for his livelihood. Because he has a golden family to feed. He volunteers to work as a traffic safety helper to secure study time for promotion. In every way, sincerity and responsibility are strong, but the crime scene is avoided under one excuse or another.

Such people meet as a 'one team' under a strong special team. Once in the spotlight for medals, they start a real fight with their cooled passion. Those who are stronger than anyone else in a hot heart that does not turn away from injustice will give a pleasant blow to the fouls of the world. The production team said, "Young people with a brilliant past as national representatives become police officers for their own reasons and blow cool uppercuts against all kinds of fouls in the world." Unexpected twists and growth will unfold in the process of gathering characters from different sports as one under the name of a strong special team. "Please watch how these characters, which actors have completed in their own colors, will breathe as one team."

Meanwhile, 'Good Boy' is a comic action youth investigation drama in which medalists who became police with specialties wear police identification cards around their necks instead of medals and fight against a world of unconscionability and foul play. It is a collaboration between director Shim Na-yeon, who directed 'Bad Mother', who won the 57th Baeksang Arts Awards TV Drama Prize, and writer Lee Dae-il, who presented differentiated genres such as 'Life on Mars' and 'Aide' series. It will premiere on JTBC at 10:40 p.m. on Saturday, May 31, and will be released to viewers around the world through the global streaming service Amazon Prime Video.
