as a teacher who frequently teach middle schoolers, this manga hurts me on a personal level. No kids should have had to go through this. The thoughts of kids younger than the ones I'm teaching, whose daily worries are trivial things like how to talk to that handsome upperclassman, going through this on a daily basis is both saddening and depressing and always left me in a state of powerlessness.
On my way to the school I'm teaching, I used to see a lot of child beggars. And seeing them gave me the same feeling, especially when I had to say I can't give u money directly to them (since giving them money would just make the problem worse). I would love to take them home, adopt them and give them proper meal, but alas my financial status wouldn't be able to support anyone of them. So I couldn't do anything at all and that always pierce a hole in my heart.
I don't see them there anymore so I'd assume either they move to another location, or the government officials had taken care of them somehow.
