After rereading the whole manga until this point, I only have this one thing on my mind:
Why is everybody being such a fucking bitch to Miwa??
Yeah, I was wondering the same thing. I can see why some people find her annoying but she actually gets better. Saeko on the other hand. She's so insufferable, but I can't be angry about it because I know there's some reason she's behaving the way she is. I want her to get better, and become more honest, but rereading and seeing all the times she lied was quite annoying.
