Alright, so I was trying to write a story of star crossed lovers. Each day they would meat on a hill and spend the sunset together. One day, a dark event happens and the next thing either of them know they are in a fantasy world. The boy a lowly bum on the streets, and the girl taken in by a strong guild. They take separate paths, unable to remember anything about the world they come from or their time together. They each remember one thing though. He remembers her smile, and she remembers his eyes. Eventually they would meat together, torn down separate paths as the man must do a number of things to survive that are not traditional fantasy ideas of the gallant hero of justice. Now, my problem is this. A good reason or no reason as to how they end up in this world together. If I go with a reason, it would have to do with multiple worlds and the dark event that happened in their original world. I have been considering not giving a reason though, to focus in on the lovers and their separate journeys that continually meet. I'm not sure what would be better for the story though. The simple question is this: Should I try and come up with a plot reason for the people to be here, or should I simply focus on the characters and their journeys.
