Perhaps in a fanfiction, Rufus and Lucy find themselves in a parallel universe where their guilds are enemies. They have to fight against each other at first, but as they learn more about the other's situation, they start to question the enmity between their guilds and their relationship takes an unexpected turn. For example, they might secretly work together to find a way to restore the original state of their worlds.
Another idea is that Rufus has a premonition about Lucy being in danger in the future. He tries to keep an eye on her without her knowing at first. But Lucy eventually catches on and at first is suspicious of his motives. As they interact more, they realize they have more in common than they thought and a bond begins to form between them.

One possibility is that it focuses on a love story between Lucy and Rufus. They start off as rivals, perhaps competing in a magic competition.

A plot could involve Freed accidentally casting a spell that links his and Lucy's minds. At first, it's a chaotic mess as they have to deal with suddenly sharing thoughts and feelings.
