Not at all. Steve and Tony have a complex relationship in their own story. By listening to Tony fanfiction, he could be trying to gain a new perspective on Tony. It's like looking at a familiar painting from different angles. Fanfiction offers different takes on a character, and Steve might be curious about those interpretations.
One of the best fanfiction moments could be when Stephen Strange uses his magic to save Tony Stark during a particularly dangerous battle. Maybe Stark's suit malfunctions and he's about to be hit by a powerful energy blast, but Strange conjures a shield of magic just in time. This shows the synergy between their powers.
Perhaps in a post - Endgame world, Tony didn't die but lost his memory. Steve takes it upon himself to help Tony regain his memories. Along the way, they re - explore their relationship, the Avengers, and all the events that led to that point. Steve shows Tony videos and tells stories, and slowly Tony starts to remember, leading to a renewal of their friendship and a new start for the Avengers.
A great fanfiction idea could be a time - travel story. Maybe something goes wrong in one of Tony Stark's experiments, and it sends Steve Rogers and Stephen Strange back in time. They end up in a time period that is crucial for the formation of the Avengers. There, they have to work together with a younger Tony Stark to set things right without changing the future too much. It would be full of interesting character interactions, as they try to figure out how to get back to their own time while also making sure the events that need to happen, happen.
I would recommend 'Steve and Tony: The Unlikely Pair'. In this fanfiction, their relationship starts off rocky due to their different ideologies but then blossoms into a strong partnership. 'Forging a New Path' is also worth reading. It shows how they navigate through political intrigue together while also strengthening their bond. 'The Promise of Tomorrow' is a heartwarming story that focuses on their hopes and dreams for the future and how they support each other in achieving them.
It could lead to all sorts of interesting plot developments. Maybe Tony would be surprised or intrigued.
In the fanfiction, Steve leaving Tony for Bucky could also make Tony more guarded in future relationships. He might be less likely to trust people easily, especially those who were close to Steve. And Steve, on the other hand, might be focused on building his relationship with Bucky, leaving little room for any kind of reconciliation with Tony.
Well, it could severely strain their relationship. Tony might feel betrayed and hurt. He could start to question Steve's loyalty. Since Steve is ignoring him for Bucky, Tony might become resentful towards both Steve and Bucky. It could lead to a rift that's hard to mend in the story.
You can start by looking on Archive of Our Own (AO3). It has a large collection of fanfictions, including ones about Steve and Tony. Just search for the relevant tags and you'll likely find many great stories.
At first, it might be a bit rocky. Tony, being used to his own space, might feel smothered by Steve and Bucky's over - protectiveness. But as time goes on, he'll start to see their good intentions. Steve's moral compass will inspire Tony to be a better person, and Bucky's loyalty will make Tony feel secure. Eventually, they'll become like a real family, with Tony looking up to Steve as a father figure and seeing Bucky as a cool older brother.
One aspect of this fanfiction could be the exploration of the complex relationship between Tony and Steve through the lens of anxiety. Maybe it delves into how their individual anxieties affect their interactions, like Tony's fear of not being good enough conflicting with Steve's anxiety about leading the team well.
