Seo Kang-jun discovered the hidden truth of the gold bullion he had been searching for so eagerly.

In the 10th episode of the MBC Friday-Saturday drama 'Undercover High School' (planned by Namgung Seong-woo, written by Lim Young-bin, directed by Choi Jeong-in, produced by Neo Entertainment and Slingshot Studio, hereafter referred to as 'Under School'), the identity of the hidden gold bullion that Jeong Hae-sung (played by Seo Kang-jun) and Seo Myeong-joo (played by Kim Shin-rok) had been desperately searching for was revealed.

In yesterday's broadcast, Myeong-joo returned to school with a flourish and shocked everyone with the keyword that Hae-sung had found related to the fourth urban legend. As soon as she arrived at school, Hae-sung was expelled, and the Domestic 4 Team of the National Intelligence Service also received a notice of team dissolution along with a standby order. Afterward, Hae-sung could not let his guard down at Myeong-joo's warning that Oh Soo-a (played by Jin Ki-joo) could also be in danger.

The members of the Domestic 4 Team of the National Intelligence Service began to dig into the truth of the fourth urban legend without giving up. While tracking the final location of the gold bullion, they sensed that there was something at the bust of Seo Byeong-mun in the school. Thus, Hae-sung disguised himself as a delivery person to enter the school; he learned that the bust was moving, and at that moment, Vice Principal Baek Gwang-doo (played by Oh Yong) appeared, and he had to escape.

Meanwhile, another crisis came to Hae-sung and Soo-a. A photo circulated within the school that made it look like the two were enjoying a secret meeting. Consequently, Principal Park Jae-moon (played by Park Jin-woo) ordered Soo-a to cease classes. At that moment, Hae-sung appeared, admitting that he had been hiding his identity and voluntarily reported his income, and the issue regarding the photo ended as a mere incident. This was because Lee Ye-na (played by Kim Min-ju), who inadvertently learned Hae-sung's identity, had given a heads-up beforehand that this situation would occur. As crises repeatedly arise for Hae-sung and Soo-a, attention is drawn to how they will survive against Myeong-joo.

On the other hand, Myeong-joo, aware that there was a hidden place related to the bust, headed straight to the school. Arriving at the school first, Hae-sung blocked Myeong-joo from entering with the words that a spy had infiltrated, while Hae-sung turned the bust and entered the basement. As he went deeper, the tension increased, and Hae-sung realized that there was no gold bullion there.

At the end of the broadcast, even more shocking facts were revealed. In the basement, where they had entered to search for the gold bullion, there were skeletal remains, and Hae-sung's watch, which he had given to his father when he was young, remained, stirring deep emotions among everyone. As Hae-sung, shedding stormy tears, poured out his feelings, anticipation soared for how he would uncover the truth behind his father's death in the next broadcast.

In this way, the 10th episode of 'Undercover High School' solved the hidden puzzle of the fourth urban legend spreading in the school and discovered a hidden underground space where the gold bullion was supposed to be. However, there was no gold bullion there, and the body of Hae-sung's missing father was discovered, piquing curiosity about how the developments will unfold.

Viewers who watched the broadcast reacted heatedly, saying, "Hae-sung really was part of the Fool 4 Team," "Seo Myeong-joo's madness is no joke, her gaze is terrifying," "Soo-a's acting is so funny," "Wow, this drama is really crazy," "Ye-na is so pitiful," "Soo-a's mom was the true strong woman," "I'm going crazy over 'Brain Picked,'" "The ending is so heartbreaking, what happened?"

'Undercover High School' will air its 11th episode and finale on the 28th (Friday) and 29th (Saturday) at 9:50 p.m.
