They’re actually not too far off. North east Asia (Korea, Japan, China etc) have a pretty bad bullying problem. Part of this has to do with a collective ideology meaning that if someone walks in one line the rest will likely follow. Of course these manwhas are exaggerated for dramatic effect but these things do happen.

Off topic, but I've always wondered how exaggerated these bullying themed manhwas/mangas are. But other than that, goo hot teacher (づ ̄ ³ ̄)づ
