For starters, was expecting an emotional breakdown, but wasn't prepared it gone written so well... this was a welcome surprise of something that's usually glanced over, but really hit me hard...
Finally Wakaba said to Nanase what should be done, she was holding back, but was too delusional in her "relationship" with Haruto and couldn't comprehend the situation she was in.
Wakaba was lying about her situation in the school from her family, too scared to ask for help because fearing of retaliation from the bullying.
Although a caring younger twin sister, Furaba didn't notice her change of mood, but Wakaba was too much focused on her "relationship" with Haruto to tell her what's going on and was always jealous of her sister extrovert personality.
Haruto overhearing the conversation between Wakaba and Ryouichi on the school roof, but only his one sided conclusion of the whole case, hopefully will hear out her explanation calmly, because the confession under pressure was too emotionally oriented...
In conclusion, Wakaba has gone through some serious mentally exhausting shit, she needs a professional psychiatric help as it should, doubtful it will be taken care of that way and resolved probably by people she met along the way.
That THOT trio deserve a serious punishment, otherwise gonna grew up to be a real menace to society.
Thanks for the scanlation!
