They're bad people, so that makes sense. but why is the mc here? As far as we're aware, he hasn't done anything illegal. And since the other girl showed their bad traits as a way to shock him suggests that is the case.
She said it's their fault, so I'm wondering what they did to make him involved? It might be the whole confessing deal since everyone that are at the games thus far were involved with that. Except I don't see how that makes him a part of anything with that.
