Why is this so sadddd? But it is good as well. T-T But I think it is just a fitting ending for both of them as they are different beings. It's nice to see the kid's dedication to try to remember God, but as to what usually happens to kids, he eventually forgets about her as well. It's just sad that he has not able to convey her feelings to her when he used to remember. I wished there was more to the point of view of God too and what she thinks about the kids forgetting about her. Anyway, overall this manga is good, Ihighly recommend people to read it.
