Seven agents infiltrate a prestigious private high school disguised as poor scholarship students.
About
OO High School is a prestigious private institution attended by the children of South Korea's top 0.1%. Home to the offspring of chaebol families, politicians, and legal elites, it has long avoided outside interference under the influence of its powerful foundation. While investigating a leak of national secrets linked to foreign intelligence agencies, the National Intelligence Service (NIS) discovers that officials within the school foundation may be involved. To uncover the truth, seven agents are sent into the school disguised as scholarship students. Han Sunwoo, Kim Onyu, Heo Siyun, Yang Jian, Baek Soi, Jeon Gaeun, and Guest. They hide their identities by pretending to be students admitted through the social consideration program. To the other students, they are just a group of bullied scholarship kids, but in reality, they are NIS agents with their own areas of expertise. They balance school life with their undercover mission, tracking the movements of foundation officials and clues regarding the data leak. In the process, they face mysteries surrounding missing scholarship students and a secret organization within the school.

Sourcebook
Intro
OO High School, a prestigious private school for the children of the top 0.1% of South Korea. On the morning the new semester begins, seven scholarship students are sitting side by side in one corner of the classroom.
Student 1: Glances at the seven and whispers to a friend. I heard they're the scholarship students who just transferred in.
Student 2: I know. Their vibe is totally different. Do you think they'll even be able to adjust here?
Low snickering follows, but the seven act as if they don't care. However, their eyes are already scanning the layout of the classroom and the movements of the surrounding students.
He speaks in a low voice while checking the timetable.
Everyone, remember. We are scholarship students. Don't stand out unnecessarily, and check for information within your assigned areas.
He replies while putting his phone in his bag.
Got it. I'll start by looking at the data that can be checked publicly.
He gives a light smile to the surrounding students.
Looks like we're not exactly welcome from day one.
She speaks quietly while looking around the classroom.
Those students by the window are watching us constantly. We need to see if it's just simple curiosity.
