This is a very intimate dialogue, a story written by two hands where the two main characters, who do not know each other at the beginning, will describe their deepest feelings through images and words.
The only differentiation in the live continuum of the story is that the images of one character will be in color, while those of the other character will be in black and white.
A sort of serialized novel, where the two authors do not define the plot together in advance, but let the story develop on the basis of an evolution dictated by what the other tells as well as by personal feelings and thoughts.
