My favorite MC is a fugged up one, d(•.•)b
I appreciate background on side characters but holy sh*t idgaf about the bully squad, move on
I think dark manga are good but to have dark you have to have light, usually a deranged MC is considered deranged when you have Normal side characters by comparison. So in this case instead of seeming crazy doing just the self monologue or constantly apologising thing, the author had to jump to crazy lengths to get them to seem more messed up by comparison to the rest of the cast. Not a good plan q(•.•)o
[In conclusion]
its dark and deals with intense bullying and a variety of abuse, sexual, parental, and emotional. And also includes (potentially) suicidal content.
I would not recommend this manga to anyone who struggles with these themes! Read tags and expect what you'll get from them.
