You don't really find out about the characters background until the epilogue. In one of the chapters, a family member mentions they are dating a wolf, so you get to think, oh, I guess they aren't angels then?
It's a short story, the characters have wings, and that's it. They don't incorporate that into the setting in anyway.
Should have just left the wings off and saved it foe another story. I shouldn't finding out what they are in the epilogue.
The concept would have been great of the author/mangka was able to extend it.
