Actor Park Bo-gum has completely transformed into fighter Yoon Dong-ju who throws himself for justice following Yang Gwan-sik, who threw himself for love.

Park Bo-gum turned into Yoon Dong-ju (Park Bo-gum), a former boxing gold medalist and current strong special forces team constable, through the broadcast of 'Good Boy' on JTBC on May 31. In the first episode, Yoon Dong-ju, played by Park Bo-gum, was caught up in a significant criminal case.

In the broadcast on this day, Dong-ju was demoted to the strong special team of the Inseong Police Agency, and he was in charge of catching a group of 'Gold Rabbit' with team leader Ko Man-sik (Heo Sung-tae) and had a major accident that he missed in front of him. Park Bo-gum's acting transformation, perfect for Dong-ju, who has a fiery personality and a hot heart who does not spare his fists, caught the eye from the beginning.




Afterwards, Dong-ju was reunited with Hanna (Kim So-hyun), whom she had a crush on since she was a player, and "Do you still like me?Without a second's hesitation when asked "Yes. Can't you do that?," and went into straight mode. In addition, he was conscious of the existence of Jonghyun (Lee Sang-i), who is almost a love relationship, and showed subtle vigilance, drawing smiles from the small screen with cute jealousy.

Dong-ju is a person who won a gold medal in boxing by appearing like a comet with a natural hawk and fist in the past, and came down from the podium of glory after being shunned by the public and the media due to the doping scandal. Although he has lived his second life as a constable, his steadfast appearance of not losing his own beliefs and never bending to anyone, like the word 'Justice' imprinted on his mouthpiece, gave him a thrilling catharsis.

Dong-ju, who accidentally hit-and-run during an undercover investigation, learned that the incident, which he thought was a simple accident, had an unusual secret. At the end of the broadcast, Dong-ju faced off with the majority of the group 'Gold Rabbit' in his bare body, drawing attention as if he were on the ring and swinging his fist recklessly.




As such, Park Bo-gum fully expresses the innocent passion and lovely pure Yoon Dong-ju character, while boldly performing action acting that does not protect the body to increase the level of immersion. In particular, the perfect action completed through six months of boxing training raises viewers' expectations. Attention was also drawn to Park Bo-gum's action scale, which will unfold in the future.

Park Bo-gum is in his prime this year, presenting a series of works on Netflix from `I was completely fooled' to `Good Boy.' Park Bo-gum not only caused the disease of 'Gwansik' across the country in Yanggwan style, but this time he continues to play as Yoon Dong-ju of 'Good Boy' to complete the 'Year of Park Bo-gum',

Meanwhile, 'Good Boy' starring Park Bo-gum will air every Saturday at 10:40 p.m. and Sunday at 10:30 p.m. on JTBC.
