Hahaha...
I have this one, and I've kept it.
The storylines are fairly different though all under a common theme. It examines the prejudice one has vs various medical conditions, as well as what it is like to experience one, without giving too much away.
I'd say there's a heroine to capture to fit just about everyone's tastes. I liked Hanako the best
It has a satisfying story length, and was quite engaging.
I found some of the art to be wanting, but I'm just splitting hairs, it wasn't enough to take away from the story.
Pick this one up, you'll like it.
