Akaku Saku Koe also has a protagonist with some trouble that have been hard on him psychologically just like natsume. The kind of calming style is also used in the story and in the art which makes sense cause it's the same mangaka. Overall, it's also a really touching story that people who read natsume book of friends will also like if they read it I think.
