This is the second thing I've read by this artist and I'm not entirely thrilled by her stuff. If she wrote longer than one shots, they would have MUCH more in character development.
This wasn't too horrible story wise, but it wasn't something amazing either. The ending was the most retarded crap in the world and Ayumi was a whore in short.
I don't recommend this unless you're really desperate to read shojo-ai/yuri.
And on the part of art- the artist needs an anatomy lesson.
The main character wasn't TOO horrible, but she was hardly explained.
