I am at chapter 18. It says that all the kids and the homeroom teacher died in that classroom in the annex building and school hid this to save face. It hasn't been explained in detail yet. But that in itself sounds so dumb. Like, a handful of school going kids and a freaking teacher died. How is that not a famous case that everyone knows about?
Also, I get that the main bully is supposedly rich and will never be held accountable for her actions, but babygirl has no loyal support from any classmates. Where does that kind of confidence even come from in a teenage kid?
