Akii's manga / #bullying(2)

In the beginning, both MCs were sort of dicks in some way. One is a bully, and the other is a bystander (doesnt do anything to help the bullied). But the more we get into the story, we get to see more character development and background, and they gradually become nicer people! Paused at ch 24

Fucking broke me. I don't know if any other works under the psychological genre will be able to top this one :')
