Look, I'm not gonna write one of those raige-bait cringe reviews or analysing this as if it was a Tarantino movie.. but I've been with this manga from the start and heck I enjoyed it. Nagatoro and Naoto were great characters who had great development and if you are still upset about the first chapter: Just don't read it.
This is not a manga about fetishising bullying, this is a story about kids growing up and realizing who they want to be. It's probably one of the best rom-coms we have right now, so why don't we just enjoy that?
