Kim Boojang's Daughter Minji: Ratings Cheat Code

The SBS Friday-Saturday drama 'Chief Kim' is creating a box office sensation, surpassing 15% viewership ratings in just two episodes. Rookie actress Seo Sumin, who plays Minji, Chief Kim's daughter, is receiving praise as a 'viewership cheat key' for her stable acting and emotional depth.

In the drama 'Chief Kim', Seo Sumin, who plays Kim Minji, the high school daughter of the ordinary office worker Chief Kim (played by So Ji-sub), left a strong impression despite it being her debut drama. The incident where Kim Minji is kidnapped by a mysterious force becomes the catalyst for Chief Kim to bring back his past special agent instincts. In Chief Kim's struggle to find his daughter, Seo Sumin led the early narrative of the drama, contributing to the recording of 15.7% viewership ratings.

So Ji-sub humorously depicted the situation of searching for his daughter in the drama by posting behind-the-scenes photos from the set on his social media with the caption, "Looking for Minji. If you've seen her." Seo Sumin also left a comment saying, "Save me, Dad," showing a father-daughter chemistry that felt natural even off-screen, which increased viewer immersion.

Born in 2007, Seo Sumin was a famous influencer with over 310,000 followers even before her debut. In particular, her past beauty YouTube channel videos, which surpassed 3 million views, first garnered attention online. She was noticed for her innocent and clear complexion, characteristic of a teenage girl, and her witty personality. With a desire to act, she signed an exclusive contract with Y1 Entertainment and began her acting career.

In its first week of broadcast, the drama 'Chief Kim' broke SBS's highest viewership ratings for 2026 and took first place in weekly mini-series. This is thanks to the tension of its provocative narrative, which rivals makjang dramas. The scene where Joo Hye-ri (played by Yoo Ji-an), the daughter of Joo Hak Construction Chairman Joo Kang-chan (played by Joo Sang-wook), attacks Chief Kim's daughter Minji with a brick and conspires to dispose of the body, shocked and terrified viewers.
