I predicted from the start that once the truth came out it was going to boomerang on those bitchy girls bad. I hope Bizen doesn't actually do something that gets him expelled, but I also hope he teaches those bitches a lesson, and that the rest of their school life is sheer hell. If anyone's ever deserved that, it's them.
I expected her to at least confess her true feelings, but I guess she had no courage to do that while being pressured like that. Or maybe she thought she had no right to do that.
Honestly I have no idea how the author plans to continue the story now, I can't predict what will happen.
What I can tell though, is that until the very last chapter(s), there won't be anything cute and wholesome anymore.
Hopefully it won't be forcefully dragged out for 10+ chapters.
Please let Bizen make the life if the bitches a literal hell. I'm so worried that the author will make them be forgiven without any real repercussions like often happens in manga...
