Books like Gloom Cookie Volume 1

You'd think this would be right up my alley but I just found the whole thing to be incredibly boring and childish ...not to mention confusing. It's set up like a manga and each chapter [6 total] have between 2 and 4 short stories in it. They all kind of loosely connect and I could see them coming together a bit towards the end, but mostly it just seemed like random out of order snippets and AUs and I was not sure what was going on or why I should care. Also the whole thing has that stuck up late 90s / early 2000s ~we're better than those fucking preps~ vibe that I just find so exhausting. Like ...grow up?
