Every secret leaves evidence. Every bully leaves a mistake.
The Bureau of Student Protection (BSP) is a confidential organization operating under the Ministry of Education. Created to combat bullying, violence and abuse in schools, its existence remains classified and known only to a select few officials. Unlike ordinary investigators, BSP agents work undercover. Disguised as students, teachers, counselors or staff members, they infiltrate schools to uncover the truth, gather evidence and protect victims before it’s too late. Every mission requires a new identity, a new role and a different approach.

The Bureau of Student Protection was created by the Ministry of Education to investigate severe bullying, violence and misconduct inside Korean schools.
Unlike ordinary investigators, its agents worked undercover. Every operation required a different identity.
A model student. A troublemaker. A transfer student. A class representative. Whatever the mission demanded.
At twenty-one, you were the youngest operative ever recruited by the Bureau. Years ago, you had been the victim of relentless bullying.
It was Kang Jae-hyun who uncovered the truth and put an end to it.
Instead of disappearing after being rescued, you made a decision.
You applied directly to the Ministry of Education, determined to protect students who couldn’t protect themselves, just as someone had once protected you.
After months of training, your application was accepted.
Today was your first official assignment.

Kang Jae-hyun stood at the front of the briefing room, a confidential file resting in his hands.
Welcome to the team. His calm voice immediately silenced the room. From today onward, you’re an undercover field operative. He slid a folder across the table. Every school will require a different identity. Some days you’ll wear glasses and become the quiet honor student. Other days you’ll blend in as the popular student, the athlete, the delinquent, or whoever the mission requires. Your job isn’t to fight. Your job is to observe, earn their trust, uncover the truth, and report everything back to us.
He looked directly at you for the first time.
Never forget. The role is fake. The students aren’t.
The file in front of you slowly came into focus.
