As a reward for his work affecting national heritage, Seo Kang-jun has become a high school student.
On the 21st, the new MBC Friday-Saturday drama "Undercover High School" depicted Jung Hae-sung (played by Seo Kang-jun) storming an underground market.
On this day, Jung Hae-sung stormed an underground market. Team Leader Ahn (played by Jeon Bae-soo) warned that they needed to protect Korea's greatest treasures, and Jung Hae-sung began to confront a Chinese broker and President Park together with Koh Young Technology (played by Jo Bok-rae).
Successfully managing to protect Korea's greatest treasures while climbing onto a moving car, Jung Hae-sung survived the vehicle accident and showcased his ace qualities. Koh Young Technology, witnessing this, exclaimed, "That's absolutely awesome," to which Jung Hae-sung replied, "Mission accomplished."
However, during the process of capturing President Park, Jung Hae-sung accidentally damaged the heritage while firing a gun, and as a consequence, was assigned the mission to infiltrate a high school.
Team Leader Ahn instructed him to find the 800 billion won in hidden gold bullion at the infirmary, stating, "The operation name is Undercover High School," and Jung Hae-sung responded, "Are you crazy? This is nonsense. How am I supposed to go to school?" To this, Team Leader Ahn persuaded him, saying, "You look very young; they say you aged because you took herbal medicine when you were younger."
