I agree!!! i dont understand the people who said this was a good read overall. the earlier the climax portion of the manga was good but the closure/ending fell through that im actually pissed for reading this. so much injustice and the fact that sugawa, the bully, got happy ending instead of kitahara just makes the original direction of the story obsolete/useless. I remember the panel where kitahara got mad that one of her bullies got a bf and she was happy but kitahara is still (even in the ending) seems miserable and i thought this issue would be addressed/tackled by the author but nope.
All in all i would say this manga is a mid read. i have a lot more to say (read: write), but i'll stop here ( ̄へ ̄)

So much hypocrisy. The characters ignored or encouraged the bullies tormenting a shy girl daily, but they made a huge deal about the masturbating incident. Even Nagaoka didn't stand up to the bullies. I don't know about you, but for me, getting my school supplies dirtied by some dude who jacked off to me is nothing compared to what Kitahara had to go through.
