Every Thursday afternoon, once a month, students at Sarang High School cast their votes in a popularity poll. The result? A brutal ranking system that determines the entire social hierarchy of the school. After starting at the bottom, can new transfer student Su Ji make her way to the top of the pyramid? Or will she topple the game altogether? Adapted from the webtoon "Pyramid Game" (피라미드 게임) by "Dalgonyak" (달꼬냑).
