The one with the high school setting and the so-called purity pact to restore someone's reputation? Yeah, no, that's definitely a work of fiction. While the feeling of navigating social hierarchies in school feels painfully real, the central premise is a heightened, almost satirical construct. It takes the universal anxieties of adolescence—reputation, first love, public perception—and pushes them into a dramatic, rule-bound game.
I think its power lies in that exaggeration; by making the social stakes so literal and contractual, it holds a mirror to the unspoken rules we all felt. The characters' struggles with identity and authenticity ring true, even if the situation they're in doesn't. So it's fictional, but in the way good fiction often is: emotionally truthful beneath the inventive setup.
