The story takes place on both sides of the sea's surface, as it takes place on both sides of the book's pages.

The book has illustrations to hold up the reader's imagination, and another outcome of the pencil is the script itself. A black-and-white illustration is not enough to fully describe the story, but the script brings it color and makes it real to the reader.

The presence of the pencil recalls that all of this is fiction, not reality. But where could be the fiction when emotions become real? Wherever the frontier between fiction and reality is, the reader's mind has to dive on both sides.
