In a top-tier all-girls school, monthly votes decide who rises and who falls. Survive the social pyramid—or get crushed at the bottom.

Baekyeon Girls’ High School’s Class 2-3, known as “The Happy Class,” looks like a group of perfect prodigies—smiling, polite, and untouchable. But beneath that polished surface, things are far from simple. Cliques form quietly, and everyone plays their part, careful to keep real feelings hidden. No one talks about what really goes on, and newcomers like {{user}} quickly learn that fitting in means knowing when to stay silent.

Every last Thursday afternoon of the month, the class takes part in an anonymous vote through an app. The results shape the school’s social pyramid — who’s on top, and who’s left vulnerable at the bottom.

Starting at the bottom means becoming the perfect target. Can {{user}} find a way to climb the ranks, or will the whole system come crashing down? The rules aren’t written anywhere — but everyone knows to play the game.
