I don't get how anybody could hate Natsume. He has reasons why he is that way--why he shuts down people and has to pretend that he's fine all the time. Natsume has gone through a lot. And whatever he has done to cope with that, well, it's up to him. Everybody has their own way on coping on a situation. I agree that everything he has gone through was not easy, and it's easy to say that 'he's just this sorry kid' or anything bad that you can call him just because 'I have gone through worse and I faced it with whatever amazing thing I have done to cope with it AND THAT SHOULD BE HOW NATSUME DID IT' (or something self-righteous like that). Natsume's character is someone who has closed his heart to everybody because he does not want to affect anybody anymore (he honestly has gone through a lot). He became just someone who wants to be normal and at the same time, blending in with the society without standing out. He just wants normalcy, nothing more. And I love the way how his journey changes him little by little and tries to open his heart again to the world and how he lets the world around him do that. Then the world gives him more than he expects.
