The anime is called welcome to the NHK people.
I enjoyed it but this is coming from a 22 year old recluse, obviously I found it relatable but I have actual reasons for my self imposed isolation. Pretty much all I do these days is work and sleep very little social life. When I was 20 all I did was go to school a couple days a week and pretty much nothing else. Watchin this anime reminds me of that time in my life. I dont go out often these days but i hang out with my old friends on occasion now. I was the complete opposite as a teenager I did nothing but party and hit on women.
Im like the main character of the show in some ways. Kind of cynical, a chain smoker, bad anxiety issues, which I never really had until after HS.
But yea unlikely a girl would help a guy like that. Nobody really would. If you close yourself off to the outside world, no one is coming to save you.
