In ‘Undercover High School’, Kim Shin-rok has been active as a ‘genre changer’ bringing tension wherever she goes.

Kim Shin-rok's presence, perfectly immersed in the role of Seo Myung-joo in MBC's Friday-Saturday drama ‘Undercover High School’, is increasingly blazing fiercely. Seo Myung-joo, the chairperson of the Byeongmun Foundation and Byeongmun High School, is a figure at the pinnacle of power, enjoying social prestige and economic success for a long time.

Embracing both intensity and coolness, Kim Shin-rok's performance has not only led the atmosphere of the drama in a new direction but also showcased the power to instantly change the genre. This was confirmed through episodes 7-8 of ‘Undercover High School’.

Seo Myung-joo (played by Kim Shin-rok) has a gentle expression that quickly turns cold. This aspect was particularly pronounced in matters related to her only daughter, Lee Ye-na (played by Kim Min-ju). Her calm eyes sparkled sharply upon seeing her daughter, as she was aware that her daughter had attempted self-harm.

Instead of expressing empathy or comfort for the pain her daughter felt, Seo Myung-joo pointed a sharp blade under the guise of advice, freezing the living room audience. Moreover, the moment a crazed smile appeared on her firmly set face, it provided a breathless sense of pressure just by watching.

Seo Myung-joo's cruel love for her daughter continued. When Han Seung-jae (played by Lee Hyun-seo) spoke ill of Lee Ye-na in front of her, she made him pay a harsh price by repeatedly slapping him, inducing a chilling tension.

Additionally, Seo Myung-joo transformed into the protagonist of a dramatic twist, standing at the center of a dynamic development. She was the one who had sent Jung Hae-sung (played by Seo Kang-joon) into the undercover high school operation. As an order to halt the operation was issued, curiosity is rising about how the increasingly sharp confrontation between the two will unfold.

In this way, the genre of Kim Shin-rok in ‘Undercover High School’ is captivating viewers. It creates a heart-pounding tension amidst cheerfulness and warmth, making it impossible to take one’s eyes off the screen.

In particular, viewers are unanimously praising Kim Shin-rok's deeply immersive performance, saying things like “Kim Shin-rok's acting is captivating,” “At this level, she seems like an acting genius,” and “Her acting is insane this time.” With her character's unique fierce gaze, subtle expressions that seem to hold many secrets, and heightened emotions, Kim Shin-rok did not miss a single detail that would amplify the tension, making the mere appearance of Seo Myung-joo give a chilling feeling. The eerie aura she created as Seo Myung-joo shook not only Seo Kang-joon and Jin Ki-joo in the drama but also the viewers.

Kim Shin-rok is responsible for the suspense or thriller-level tension in ‘Undercover High School’. Expectations are rising for what kind of fun will begin from her increasingly intense performance.

MBC’s ‘Undercover High School’ airs every Friday and Saturday at 9:50 PM.
