I lost track of this manga long ago but now that I found it again makes me very joyful.
I thought the story would be more sadder and unsuspected as it approached to the end but I guess it wasn't like I expected, but i anyway liked how all ended. I don't thing an ending with Satoru meeting with his family once again wouldn't be any good for the manga to end, i think the mangaka did good on how it ended the manga because of the way it ends relies on the imagination of what the reader want to imagine what it should happen after.
summary the manga doesn't give you the feel of ``what to do next´´ or that empty feeling after finishing something, instead it gives you the vibe of a story that doesn't have an end ''yet''.
don't mind this review, I am just practising the way i write just like an sketch of a drawing before you come the real deal.
