The issue I've always taken to this sort of introvert/NEET/bum-given-a-second-chance sorta thing is that their past experiences are always so incredibly wack. And I understand this may be because despite having my introverted times, I was never really ostracized and bullied like these characters, but it does make these series less relatable to me when the "trauma" they overcome is people being comedically evil and disproportionately mean for no reason.
