Kim Ui-sung, Jo Jae-yoon, Lim Cheol-hyung, Oh Ui-sik, Kim Kyung-hwa, and Ahn Nae-sang made special appearances in 'Undercover High School,' radiating an extraordinary presence.

The MBC Friday-Saturday drama 'Undercover High School' (planned by Nam Gung-seong, written by Lim Young-bin, directed by Choi Jeong-in, hereinafter 'Under School') is attracting the attention of drama fans with unique characters such as Jeong Hae-seong (played by Seo Kang-joon), Oh Soo-ah (played by Jin Ki-joo), and Seo Myeong-joo (played by Kim Shin-rok). Furthermore, the combination of these characters, which captures attention even with a brief appearance, is also generating interest.

First, Kim Ui-sung played the role of Seo Byeong-mun, the founding chairman of the Byeongmun Foundation. He perfectly depicted the story of having to flee after misappropriating gold bullion received from Emperor Gojong, focusing attention on his character.

Jo Jae-yoon took on the role of Gu Sang-tae, who runs an illegal gambling site, contributing to the plot by testifying that Park Tae-soo (played by Jang Seong-beom), embroiled in school violence, frequents the site. From the first scene, he appeared wearing a facial mask, eliciting laughter, while delivering a delightful performance in every scene, catching viewers' attention.

Lim Cheol-hyung played the role of Team Leader Gong, head of Team 1 at the National Intelligence Service. Serving as the right-hand man to Director General Kim (played by Lee Seo-hwan), he always kept an eye on Team 4. Particularly, when An Seok-ho (played by Jeon Bae-su) brought in a national treasure with a broken arm, he humorously remarked, "Team 4 is quite incompetent, but they wouldn't have done that on purpose."

Meanwhile, Oh Ui-sik appeared as Jeong Jae-hyun, Hae-seong's father, intricately portraying a poignant childhood story. Hae-seong is currently in pursuit of the whereabouts of Jae-hyun, who vanished suddenly, raising curiosity about how Hae-seong will uncover that truth in the future.

Additionally, Kim Kyung-hwa vividly expressed the role of a mother actively trying to protect her son Tae-soo, who is caught up in a school violence incident, with a versatile use of speech and expressions. He played a significant role in advancing the central storyline, further enhancing viewer immersion.

Finally, Ahn Nae-sang's surprise appearance overturned expectations. When Soo-ah suddenly paid a home visit, Team 4 decided to fill Hae-seong's empty house with necessary items borrowed from neighbors. That neighbor was Ahn Nae-sang, who delivered a fresh laugh to viewers with his brief yet skillful performance.

Such special appearances by Kim Ui-sung, Jo Jae-yoon, Lim Cheol-hyung, Oh Ui-sik, Kim Kyung-hwa, and Ahn Nae-sang have contributed to adding vitality to the storyline, leaving a strong impression that made it hard for viewers to look away, inciting admiration.

Meanwhile, according to the official platform of Good Data Corporation, FUNdex, 'Undercover High School' secured the top spot in TV-OTT drama buzz for two consecutive weeks, following the third week of February. Additionally, it also topped the integrated TV buzz rankings for dramas and non-dramas, with Seo Kang-joon rising to first place in the participant buzz rankings for two consecutive weeks, proving its high level of interest.
