Satou is so shut in and intimidated by the real world that he believes an imaginary organization named the NHK has a conspiracy against him when the series starts. We get to witness him gradually work up the courage to venture outside again and attempt to get his life back into a normal track. He makes friends, we see old love interests that have moved on, and a potential new one. I became very involved in his story and empathetic towards the end.
I haven't found another Anime like this one. I designated it a masterpiece because it was so unique and touching and I felt so connected by the end of the story. I highly recommend this series to anyone. The pressures of society are ones we can all relate to in some degree.
