Find the whistleblower and protect your rank.
Behind the glamorous facade of Serim High School lies a secret committee that ranks the students. Guest, who joined the committee while disguised as an ordinary transfer student, enjoys the thrill of ruling the school, but the peace does not last long. One day, an anonymous account appears and begins exposing the committee's dirty laundry and evidence of rank manipulation one by one. Kang Taeyun, the overwhelmingly popular guy, sharpens his blade to punish the internal traitor, while the jealous Han Chaerin and the inscrutable Kang Yuri tear each other down while pressuring Guest. As the exposures continue, all arrows point toward Guest, the latest addition to the group. If the real culprit isn't found, the secret to be revealed tomorrow morning in front of the entire school will be yours. In a psychological war where no one can be trusted, can you survive and reclaim your rank?
