Seo Kang-joon and Kim Shin-rok engaged in a fierce battle of wits without giving an inch to back down.

In episode 9 of MBC‘s Friday-Saturday drama ‘Undercover High School’ (planned by Nam Goong Seong-woo/written by Lim Young-bin/directed by Choi Jeong-in), Jung Hae-sung (played by Seo Kang-joon) and Oh Soo-ah (played by Jin Ki-joo) safely returned to school, while Seo Myung-joo (played by Kim Shin-rok), who had been investigated by the police for a corruption case, reappeared, leaving everyone frozen. The viewership ratings for that day were 6.1% based on Nielsen Korea’s nationwide household ratings. In particular, the scene where Hae-sung, who was cleaning the school, and the students of Class 1, Grade 2 took a group photo soared to 9.1%, doubling the heartwarming atmosphere of the drama.

The shocking truth about the corruption in school grades was revealed in that day‘s broadcast. The assailant who attacked Soo-ah and the person who carried out the corruption at school were math teacher Lee Jun-ho (played by Noh Jong-hyun). Haesung found out that Junho had taken his father’s notebook under Myungju‘s orders, and Junho begged Myungju to protect him, but she coldly ignored him, raising curiosity about whether Junho would be able to return to his place.

The part where he dealt with Myungju’s henchman Park Jaemoon (Park Jinwoo) was refreshing. Park Mijung (Yoon Ga-i) and Go Younghoon (Jo Bok-rae), who were watching Junho, saw him getting into Park Jaemoon‘s (Park Jinwoo) car and chased after him. However, before Haesung arrived, the two were unable to control their overflowing enthusiasm and confronted Jaemoon’s gang, but they ended up getting beat up in return, making everyone laugh. Haesung, who arrived late, quickly sorted out the situation, presenting tension and exhilaration at the same time.

Haesung headed to the chairman‘s office where Myungju was to catch her off guard. He asked why she had put him in this operation instead of someone else, and then pressured Myungju by showing her the news of Junho appearing at the police station. Not only that, he cornered her by pulling out the crucial evidence on the USB. Despite this, Myeong-ju stood firm and even gave an eerie smile when she was cut off from Director Kim (Lee Seo-hwan), with whom she had an affair.

At the end of the broadcast, Myeong-ju and Jae-moon appeared together while the superintendent visited the school, shocking everyone. Myeong-ju greeted Soo-ah sharply, creating a chilling atmosphere, while she tore off Hae-sung’s name tag, saying, “Student play is over,” and the tense atmosphere between the two reached its climax.

In this way, the 9th episode of ‘Undercover High School’ led the viewers‘ immersion to the peak with Hae-sung and Myeong-ju’s struggle to get one step closer to the final ghost story. In addition, as the internal corruption scandal was resolved, the conflict within the school seemed to have decreased, but Myung-joo‘s reappearance overwhelmed the atmosphere, raising expectations for the next episode.

Episode 10 of ‘Undercover High School’ will air at 9:50 p.m. on the 22nd (today).
