There is no real - life love story between AJ Lee and Roman Reigns. In the WWE universe, they are just colleagues who have their own separate storylines and characters.
In some fan fiction, there might be a plot where Roman Reigns time - travels back to the early days of wrestling. He uses his modern skills and knowledge to change the course of wrestling history, and along the way, he has to deal with the different styles and egos of the past wrestlers.
Another option is Wattpad. There are some good 'Roman Reigns fanfic' on there. You might have to do a bit of searching through the wrestling or WWE tags, but it's worth it as you can discover some unique stories written by fans.
I liked a Roman Reigns fanfic that was set in a post - apocalyptic world where wrestling was the only form of entertainment left. Roman had to fight against various villains to restore order in the wrestling arenas. It was full of intense battles and the author did a great job of portraying Roman's leadership skills in a unique scenario.
Well, it could lead to all sorts of drama and conflict within the wrestling storyline. Maybe it would trigger a revenge plot or a series of intense rivalries.
As of now, it's mostly a rumor. There's no official confirmation from either of them about a romantic relationship. They are both great in their own wrestling careers and might interact professionally, but that doesn't mean there's a love story.
A prevalent theme is family - like relationships. In 'Roman Reigns Daddy's Girl Fanfiction', it's not just about the basic father - daughter dynamic. It can also involve the whole idea of family support. For example, Roman Reigns might be there for the girl during tough times in her personal life or in her wrestling journey if she's also a part of that world in the story. There can also be themes of growth and learning, where the girl character learns important life lessons from Roman Reigns.
John Cena is another character that gets paired with Roman Reigns in fan fiction. There could be stories of them competing for the top spot in the WWE, or they could be forced to team up against a common enemy, leading to some interesting character dynamics.
