Seo Su-min has made a striking impression on viewers as MINJI, the daughter of the protagonist Agent Kim (played by So Jisub), in the SBS Friday-Saturday drama Agent Kim Reactivated (written by Nam Dae-jung, directed by Lee Seung-young and Lee So-eun).

While MINJI may appear to be an ordinary high school student, she is, in fact, the absolute reason that drives Agent Kim to act and represents the very world he is willing to risk his life to protect.

In the first and second episodes of Agent Kim Reactivated, MINJI was thrust into the center of the plot. When a shocking incident occurs where she suddenly disappears, Agent Kim’s peaceful daily life is completely shattered. Her disappearance serves as the decisive catalyst for Agent Kim to take action, effectively heightening the tension of the entire series to its peak.

Although this is her first drama role, Seo Su-min has brought depth to the character of MINJI with a performance that belies her status as a newcomer. She delicately portrayed not only the bright and fresh image of a high school girl but also the resilient inner strength of a character who endures hidden wounds at school and stands up against injustice. In particular, her ability to navigate the complex emotions of both affection and resentment toward her father has been praised for adding deep conviction to the father-daughter narrative with So Jisub.

The foundation that allows this drama to transcend a simple thriller and embrace a profound sense of humanism lies in the story of this father and daughter. There is growing curiosity about how the narrative will unfold as the father embarks on a desperate struggle to save his daughter, and how her own emotional changes will be revealed throughout the process. All eyes are on how rookie Seo Su-min, who has successfully made such an impressive debut, will continue to enhance the immersion of the show.

Agent Kim Reactivated, featuring the brilliant chemistry between So Jisub and Seo Su-min, airs every Friday and Saturday at 9:50 PM.
