Story:
In short this manga is about someone who lost the person that they loved. That premise alone is nothing new but it adds a very interesting take on that by giving you not only the perspective of the main character but also the woman he lost watching over him from heaven. The author does a good job of peppering in a bit of symbolism as well as making the story interesting in a very short amount of chapters.
Art:
The art is well done. It is not the greatest art I've ever seen in a manga but it works.
Characters:
The characters lack depth which is inherent with a short story like this one.In my opinion the characters are the weakest part of the manga because they don't really get fleshed out and that makes it harder to connect with them.
Overall:
This story does a lot of things well in a short amount of chapters. It has flaws but it is definitely something worth reading.
