I must say that if watched with an open mind, it is very very touching, mind opening and heart wrenching. The characters know damn well what they're doing and the risks and taboos associated with their relationship and this moves the anime into being a tear jerking testament of the character's inner struggles with accepting their feelings... and having the courage to follow them.
Story
As I've said, the story is fabulous. The portrayal of emotion in this series is so intense and so thorough that you grow to feel the characters' pain and understand a great deal of the extent of their struggles. The series is written in way that makes the characters completely vulnerable to the viewer-- you see everything they feel and go through. Their weakness and their strengths, the extent of their true feelings for each other-- until the characters are so real and their relationship so fleshed out that you actually come to an understanding of why they come to feel and act the way the do. The thing that is truly brilliant about the story, however, is the pacing. The story is slow but deliberately so. You really see the characters feelings develop over time and their relationship blooms at a beautiful rate so you get to see the full intensity of it.
Overall, the story is achingly beautiful in its portrayal of emotions and human tendency and honest to the point of realism.
Art
The art is...beautiful. It is quite simple but in a way that compliments the anime completely and beautifully detailed and even original. The character design is great: the characters look unique in a very realistic way.
Sound
The acting is superb...the voices fit the characters really well too.
The music is absolutely gorgeous and very touching. The main piano piece that's played throughout is one of the most beautiful I've ever heard...I remember it bringing tears to my eyes on numerous occasions.
The music, like the anime, is simple and low-key but the undertones are incredibly touching and add to the somber yet intensely emotional feel of the anime.
Character
The characters as I've probably mentioned are very well developed to the point of seeming real. Their very human emotions and how they act in reaction to what they feel are extremely relatable and believable.
Enjoyment/Overall
Koi Kaze, when watched with an open mind, is probably one of the most insightful and moving animes every created. It's also by far one of best written series I've ever seen. Though the themes in this series are extremely controversial I think that they could not have been handled in a more deeply sensitive and analytical way. I think this anime is one of the best portrayals of human nature and love out there.
