After Oyasumi Punpun this might be my favorite Inio Asano work. This is a collection of One-shots and each one of them could easily be a story. Not sure if he developed some of these into later works but every time I finished one of them it left me wanting more. Inio Asano is a master at creating very emotional and human characters that not only feel real but also relatable. His works tend to be on the sadder side but it feels so real and human that you don't want to stop reading. Combining that with his beautiful and very distinguishable art style, it makes the experience very immersive and you just don't want to leave.
Highly recommend.
