A new girl shows up trying to do everything right and gets fed into a machine designed to destroy her. The Pyramid Game doesn't ask why she's the target, it just needs one. You watch her realize that kindness won't save her, that the system doesn't care about innocence, that escaping means you have to become something harder than the girl who walked in on day one. By the end, the real horror isn't the bullying, it's what she has to become to survive it.

Su-ji, a student used to changing schools often, joins Class 2-5 at Love High School around August. As usual, she greets her classmates warmly and tries to make friends. Then she learns about the Pyramid Game, a popularity vote held on the last Thursday of each month. Its ranking sets the social order of the class, and the least favored student gets an F and becomes a target for bullying. Su-ji starts at the bottom and faces harsh bullying while the class operates under Harin Baek's rule. She fights to get out from under the outcast label, and the question is whether she can rise through the ranking or bring the whole system down. The drama and thriller series runs nine episodes.
