The most realistic anime out there. And, possibly, the most depressing. This anime stuck with me for so long because of how relatable Satou was (to an extent). It definitely highlights some very real aspects of life like social anxiety which were sad to see in our main character. I genuinely started to view my own life differently and change myself after watching it and for that reason, it will remain my favorite anime and manga of all time. I don't think I'll ever forget the feeling NHK gave me.
