Somewhere in the world the person you are going to marry/be with or whatever is writing their story. By that I mean the story you will one day know all about. But for now, you two are on opposite sides of the world (figuratively or even literally) completely unaware of each others existence. The only thing you two are worried about is continuing to write this story that even you yourselves don't fully understand. Despite having an idea of how you want this story to go, you have little control on how things turn out.
But if you do know/are with the person you are going to be with, then from this point on that story is co-written by the both of you. You will wonder and ask about the story from before the point of which you became apart of it because of a subconscious fear we all have in the unknown, but you should only care about the story that has still yet to be written.
