In the drama 'Agent Kim Reactivated,', "Live well with your daughter": The transformations of Kim Seong-gyu and Kim Ji-hun

Actor Kim Seong-gyu has left a powerful impression in the drama 'Agent Kim Reactivated,' transforming a character fueled by vengeance into one filled with humanity. In the series, Kang-seong pursues Lee Eung-ryeong (Lee Jae-yong), the man responsible for his brother's death, leading to a confrontation with Agent Kim Reactivated, played by So Ji-sub. However, upon realizing that Agent Kim Reactivated is fighting to protect his daughter, Kang-seong shifts the course of the story, choosing to say, "Live well with your daughter," instead of pulling the trigger. As the misunderstanding surrounding his brother's death is resolved, he undergoes a transformation from a simple avenger to a character deeply marked by past wounds.

Kim Seong-gyu portrayed everything from Kang-seong's vengeful nature to his human side through cold gazes and restrained emotional acting. He completed the character's multi-dimensional depth by depicting the warmth hidden behind the facade of a ruthless pursuer.

From Yang Tae to Writer Ko: A Versatile Acting Spectrum Built on Genre Films

Kim Seong-gyu's acting spectrum spans across various genres. Since his debut in the 2011 play 'Twelve Angry Men,' he has expanded his presence, notably appearing in the film 'The Outlaws' as Yang Tae, the right-hand man to Jang Chen (Yoon Kye-sang), where he simultaneously displayed a bright expression and brutal actions. His unrestrained energy heightened the tension of the film despite his brief appearance.

He subsequently broadened his career through films such as 'The Gangster, the Cop, the Devil' and 'Hansan: Rising Dragon,' and dramas like 'Kingdom' and 'Taxi Driver.' Notably, in the SBS drama 'Taxi Driver 3' released in January 2026, he played Ko Seong-hyeok, a former prosecutor and the leader of the Samheung Do-pa gang. He delivered an impressive performance, heightening the tension with an unreadable expression and a calm tone.

Boxing Trainer Kim Ji-hun Takes on a New Challenge in Variety Show 'Iron Girls'

Actor Kim Ji-hun, who appeared in 'The Roundup: Punishment,' is transforming into a boxing trainer and variety show producer. Having proven his leadership by leading all participants to victory in the boxing project of the tvN variety show 'Iron Girls,' he is launching a new reality growth program, 'Iron Girls.'

'Iron Girls' is a reality project capturing the process of ordinary women overcoming their limits and finding life changes through boxing. In this project, three actresses and one creator will participate, facing their respective fears and limitations. Kim Ji-hun will be directly involved not only in boxing training but also in the planning and production of the program.

Actor Ma Dong-seok has joined as a production supporter, sympathizing with the program's purpose. Kim Ji-hun stated, "'Iron Girls' is not a program designed to make people good at boxing. It captures the process of facing one's own limits, overcoming them, and growing into a stronger person." He added that he hopes viewers will find new courage in their own lives by watching the participants' challenges and transformations. 'Iron Girls' will be released starting in early August through trainer Kim Ji-hun's YouTube channel, with various episodes and behind-the-scenes content to be uploaded sequentially.
