Seo Kang-joon is faced with the biggest crisis of his life.

Episode 10 of MBC‘s Friday-Saturday drama ‘Undercover High School’ (planned by Nam Goong Sung-woo/written by Lim Young-bin/directed by Choi Jung-in) depicts Jung Hae-sung’s (Seo Kang-joon) difficult life at the National Intelligence Service.

In the episode broadcast on the 21st, Hae-sung and the 4 domestic teams of the National Intelligence Service joined forces to uncover the internal grade corruption case carried out by math teacher Lee Jun-ho (Noh Jong-hyun) at Byeongmun High School and even revealed that Chairman Seo Myung-joo (Kim Shin-rok) was behind it, giving a refreshing treat. However, that was short-lived as Myung-joo and Park Jae-moon (Park Jin-woo) appeared along with a visit from the scholarship officer, surprising everyone. In particular, the scene where Haesung and his friends from Class 1, Grade 2 take a group photo while cleaning made the viewership ratings rise to 9.1%, making viewers smile.

In episode 10 that will air today (the 22nd), Haesung is hit with one misfortune after another. Haesung, who was at school, is in a situation where he is at a loss as he is on the verge of expulsion. If Haesung leaves the school, the whereabouts of the gold bars, which are the core of the operation, will not be found.

Not only that, but the 4 domestic teams of the National Intelligence Service are searched and seized, and eventually the team leader Ahn Seok-ho (played by Jeon Bae-soo) is summoned. It makes one wonder what solution Haesung will come up with in response to the series of crises that occurred in an instant.

In the midst of all this, the tense tug-of-war between Haesung and Myeong-ju shows no sign of ending easily. Myeong-ju is said to become more and more vicious after this. Attention is being paid to who will have the last laugh in the gold war where one cannot see even an inch ahead.

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