Hae Seong ends everything

Undercover High School content before episode 11, 12

Episode 10 of Youth Mission begins with the dramatic return of Seo Myeong-ju and Principal Park to the school. Myeong-ju reveals that she knows the clues about the pearl and the sunrise, and asks Hae-seong to leave the school. After being expelled by the council chairman, Hae-seong bids farewell to her friends and continues her investigation with her team, even though their office is suddenly raided by NIS internal investigators. They discover an illegal sum of money and arrest Seok-ho, which escalates the situation. Myeong-ju calls Hae-seong, taunting him with a "parting gift" and threatening Soo-a, but Soo-a encourages Hae-seong to continue despite the danger, and gives him a student council book with a picture of his father.

Hae-seong's team is disbanded, but they decide to continue their investigation from his home. They discover a fourth ghost story in the notebook, involving a self-lighting computer and a message from a dead teacher, which Hae-seong believes his father added to trick Myeong-ju. Focusing on the phrase "When the bearer of the jewel faces the red sun, gold will shine," they suspect the statue of Seo Byeong-mun at the school is the key. Hae-seong disguises himself as a delivery man to infiltrate the school, and together with Soo-a, discovers that the statue can rotate, but is interrupted by Vice Principal Baek. Meanwhile, Myeong-ju realizes that Hae-seong has infiltrated and orders the "second gift" to be sent, leading to the release of photos of Soo-a and Hae-seong, suggesting an inappropriate relationship between teacher and student.

Hae-seong deals with the situation by revealing his true age (31) in front of the class, admitting to liking Soo-a and gaining support from the students, angering Myeong-ju. With help from Ye-na, he continues his plan to find the gold. Hae-seong's team receives unexpected support from Soo-a's mother, a former member of the Bloody Chicken Gang, to stop Myeong-ju at school. At the end of the episode, Hae-seong turns the statue, discovering a secret door leading to an abandoned room where he finds his father's skeleton, but no gold. The episode ends with many unanswered questions, leaving the suspense for the next developments.

Prediction of Youth Mission episode 11, 12

After discovering his father's skeleton under the Seo Byeong-mun statue with a nearby bullet wound, Hae-seong falls into deep grief. He and Seok-ho request the forensic team to examine the remains.

The report confirms his father was shot, and Seok-ho points to Director Kim as the prime suspect, as he had met Hae-seong's father before he disappeared.

Meanwhile, Seo Myeong-ju arrives at school and, angry that she hasn't found the gold, begins to suspect that Hae-seong knows something. Hae-seong, with Soo-a's support, decides to confront Director Kim directly. He brings a gun, points it at Kim, and demands the truth. Under pressure, Kim admits to shooting Hae-seong's father and taking the gold, but adds that the gold still exists and that he knows where it is hidden. Hae-seong, instead of pulling the trigger, secretly bugged Kim's house to gather evidence, and at the same time plans to find the gold.

Elsewhere, Myeong-ju desperately tries to force Hae-seong to reveal information by recounting the story of how his father once searched for gold, but her plans are interrupted when a car accident occurs – possibly related to the chase between her and Hae-seong.

Hae-seong overhears Director Kim's conversation, pinpoints the exact location of the gold, and springs into action. He and his team, with the support of Soo-a's mother's Bloody Chicken Gang, stage a raid to retrieve the gold and bring those responsible to justice. Meanwhile, Myeong-ju, injured from the accident, attempts to stop Hae-seong, but is arrested by the authorities when they arrive at the scene. Hae-seong faces the danger of being shot in a confrontation with Kim's forces or the police for disobeying orders, causing Soo-a and his team to rush to the hospital in a panic.

Fortunately, he survives and recovers, determined to complete his father's mission. In the end, the gold is found, and Director Kim and Myeong-ju are punished for their crimes – Kim for murder and corruption, Myeong-ju for her greed that led her down the wrong path with her plan to turn the school into an "Edu City". Hae-seong gets justice for his father, while Soo-a officially becomes a teacher, continuing to protect the students. The relationship between Hae-seong and Soo-a has the opportunity to develop deeper, possibly ending with a meal that Soo-a promised after everything is over, opening up a bright future for both of them.
