I wasn't expecting much from this one but I surprisingly enjoyed myself. I didn't like the art particularly much, it wasn't bad but everybody had the same childishly-thin body shape. From the character design, I found it hard to believe that some of these characters were 30 years old. All the characters looked the same age...
Main story (ch1-3): This one was melancholic and slightly dark. I enjoyed it and it was not cliched-predicable at all. I saw the whole fairy thing as a metaphor; the ex accepting his homosexuality and the lead dealing with his depression.
Second story (ch4): This is just snippet of the life of an established gay couple. Though it was only touched on briefly, I really liked the commentary on the state of women's and gay social issues in Japan. I also liked the mature, domestic relationship the two characters had with each other. It was very refreshing to see such interactions portrayed so realistically in yaoi.
Third story (ch5): A very sweet and sexy oneshot. The kotatsu sex was very hot! This was very light-hearted and cute.
Fourth story (ch6): This one was bit less developed than the other stories. I had to make a few assumptions in order for it to flow well for me. But it was still good and a bit more emotionally complex than other yaois.
Overall: The stories were exceptionally well thought out, even if the art was a bit lacking. I highly recommend it to those of you who want a slightly different approach to yaoi.
