Their creator abandoned them. He left them behind on a beach with their happily-ever-after; he thought that was enough.
There is no such thing as happily ever after. Life goes on. When all they have known is gone forever, two ordinary people must pick up the pieces and start again.
In these stories, they have their chance. The chance to overcome grief and loss; to create a life together; to discover new passion, new adventures. These characters have it in them to adapt, to find joy wherever they look. Here, they find it in an ordinary world.
An ordinary life.
There is no such thing.
Enjoy the adventure.
