Watashi no Tomodachi ga Motenai no wa Dou Kangaetemo Omaera ga Warui. · review
If you're like me and are a big fan of Watamote, this will help satiate your thirst for more content. It involves quick little stories about the old middle school trio - Tomoko, Naruse, and Kotomi get up to their antics. It's funny how much Tomoko and Kotomi have beef, I prefer the more frenemy context in later chapters of the main manga. Tomoko seems like a bit of an asshole here and it makes it hard to sympathise with her, but that's the point. It's important to understand where Tomoko was originally coming from before the original manga started, and these cheeky stories help illustratethat.
These are enjoyable stories that you will enjoy, given you like Watamote. I recommend reading them after catching up with the manga, it's fresh air from the manga which has gone a much different direction from where it was originally (not a bad thing though IMO). This one's good, a 7/10.
