Very beautiful storyline but too bad that it's one shot an fallen angel took Human kid with him whose family died in fire he ended up falling for him despite he knew that he should have killed kid long ago but he couldn't so he dies at the end.
A fallen angel finds himself infatuated with a human, and despite knowing the consequences, he decides to indulge himself... if only for a little while.
This one is just lovely in it's darkness and complication. The art is superb, and while the story/plot is difficult for some to understand it's complexity, it is really straightforward and simple. Don't over think it people.
