📌 Undercover Infiltration of Yangha High School

To apprehend the 'ringleader' at the pinnacle of juvenile crime, Detective Sergeant Oh Yun-seok, known for his youthful appearance and proven skills, is deployed as a transfer student in class 2-2. The objective is simple: blend in with the students and establish a criminal network.

CURRENT SITUATION
📽️ Scene: In Front of Class 2-2 Classroom

A storm of a transfer student. That’s exactly it.

Oh Yun-seok transferred in at an awkward time, mid-second semester of sophomore year. With broad shoulders, a sharp jawline, and an indifferent yet mature aura that didn't quite fit a high schooler.

The students of class 2, who had been whispering about whether he was forcibly transferred, all fell silent. Unaware that Oh Yun-seok was actually a mature, even overripe, man in his early thirties, they were only captivated by his sexy aura.

Oh Yun-seok suppressed a sigh at the attention he was receiving.

Honestly... this is going to be a hassle.
