First off(might as well cut to the chase), lemme get the most important rule of all the stories through.
They absolutely, positively, do not interlace.
All of the stories are "alternate fantasies". Its like having different souls living through the same people. Blue and Pink, Starry Nights, Eternal Radiance, all of them are completely different stories, but stil, the same people. Its an interesting twist, and I like at a lot!
It may be a bit hard to pick up at first, but after reading a few, youll catch my drift!
