Seo Kang-joon has found out the hidden truth about the gold he has been searching for.

In episode 10 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/produced by Neo Entertainment, Slingshot Studio/hereafter ‘Underschool’), the identity of the hidden gold that Jung Hae-sung (played by Seo Kang-joon) and Seo Myung-joo (played by Kim Shin-rok) have been desperately searching for was revealed.

In yesterday’s episode, Myeong-ju returned to school as if nothing had happened, and was shocked to find out that she knew the keyword that Hae-sung had found in relation to the fourth ghost story. As soon as she arrived at school, Hae-sung was expelled, and the National Intelligence Service‘s domestic team 4 was also notified of the team’s disbandment along with a standby order.

After that, Hae-sung couldn‘t let his guard down because of Myung-joo’s warning that even Oh Soo-ah (Jin Ki-joo) could be in danger.

However, the members of the National Intelligence Service‘s domestic team 4 did not give up and began to dig into the truth of the fourth ghost story. While tracking the final location of the gold bars, they instinctively felt that there was something with the bust of Seo Byeong-moon at the school.

So Hae-sung entered the school disguised as a deliveryman and discovered that the bust was moving. At that time, Vice Principal Baek Gwang-doo (Oh Yong) showed up and had to get out of there.

Meanwhile, another crisis came to Hae-sung and Soo-ah. A photo of the two of them seemingly having a secret meeting was spread around the school. Principal Park Jae-moon (Park Jin-woo) told Soo-ah to stop class. At that moment, Hae-sung appeared and voluntarily paid taxes, saying that he had been hiding his identity, and the incident with the photo ended as an incident.

This was because Lee Ye-na (played by Kim Min-joo), who accidentally found out Hae-sung’s true identity, had warned him in advance. As Hae-sung and Su-ah face repeated crises, attention is focused on how they will survive against Myeong-ju.

Myeong-ju also found out that there was a hidden place inside the bust and headed straight to school. Hae-sung arrived at school first and blocked the entrance, saying that a spy had infiltrated, so that Myeong-ju could not enter. In the meantime, Hae-sung turned the bust and went into the basement. The deeper they went, the more tense it became, and Hae-sung realized that there was no gold there.

An even more shocking fact was revealed at the end of the broadcast. In the basement where they went to find the gold, there was a skeletal body, and the watch that Hae-sung gave his father when he was young was still there, making everyone‘s hearts ache. Here, Haesung, who shed tears and poured out his emotions, is raising expectations for the next episode to see how he will uncover the truth behind his father’s death.

In this way, episode 10 of ‘Undercover High School’ solves the hidden mystery of the fourth ghost story spread throughout the school and finds an underground space where gold bars are said to be hidden. However, the gold bars were not there, and Haesung‘s missing father’s body was discovered, making viewers curious about how the story will unfold in the future.

MBC‘s Friday-Saturday drama ‘Undercover High School’ will air its 11th and final episode on the 28th and 29th at 9:50 PM.
