Undercover High School Plot
Byungmoon, Korea’s top private high school, is rife with corruption, where status and success matter most. Hae-sung, a top NIS agent, goes undercover at Byungmoon to find Emperor Gojong’s hidden gold and uncover the truth behind his father’s disappearance. Cold and calculated, he sees the school as an obstacle—until he connects with students and a former crush and becomes a reluctant hero. Torn between duty and newfound bonds, can he still complete his mission?
