From the manga Watashi ga Motenai no wa Dou Kangaetemo Omaera ga Warui!
Reading the manga It’s not my fault I’m not popular makes me cringe . Her action somewhat reminds me of my stupid self.
I am a loner too but I wasn’t as desperate as her and I certainly did not think unhealthy stuff like she does.
However the recent chapter has less cringes as she seems to be making a few friends.
Moral of the story – Get some friends to spend time with or buy a MMO game and get some friends inside MMO.
