Fleur could become an ambassador between the wizarding communities of Britain and France. Harry, having a great reputation, could support her in this role by being a symbol of unity. He might also write books about his experiences, which could be used in magical schools as a way to teach about the importance of fighting against evil. In this way, they both have careers that are intertwined with the betterment of the wizarding world.
In post - Hogwarts fanfiction, Harry often develops into a more confident leader. He has already defeated Voldemort, so he uses his experience to mentor the next generation. Hermione, on the other hand, may become more assertive in the academic and political aspects of the wizarding world.
It's also likely that Harry, having faced so much darkness, decides to take a break from the wizarding world for a while. Fleur, on the other hand, is still very much involved in the magical community. She might persuade Harry to come back and they start to explore different magical cultures together. They could travel to far - flung places, discover new spells and magical creatures, and in the process, their relationship blossoms.
Often, Harry's sense of responsibility grows. He starts to see the marriage contract as not just a burden but also an opportunity to create a new life for himself and Fleur. Fleur's personality may develop in a way that she becomes more protective of Harry. For example, when they face opposition from the wizarding community about their contract, she stands up for them. She also might help Harry to overcome his insecurities about being in a relationship with someone as glamorous as her.
At first, their relationship might be a bit strained. Harry is used to his own space and friends, and Fleur has her own circle. But as they live together, they'll start to respect each other's differences. For example, Fleur might be more flamboyant in her magic use, while Harry is more practical. They'll start to see the value in each other's approaches and become closer friends.
If there was a rivalry before Hogwarts, it could carry over and make their interactions at Hogwarts more tense. However, this could also lead to them pushing each other to be better. For example, in Quidditch, if Fleur is also a good flyer, Harry might strive to outperform her, which could improve his skills as a Seeker. And over time, this rivalry might turn into mutual respect.
At first, they might be at odds with each other. Fleur could think Harry is too impulsive, while Harry might find Fleur a bit too haughty. But then, when they are forced to work together on a mission, they see the good in each other. Fleur realizes Harry's selfless nature, and Harry sees Fleur's intelligence and determination. This new - found respect leads to a romantic relationship and ultimately marriage.
Their meeting could also mean that Fleur might be more protective of Harry at Hogwarts. Since she knew him before, she might feel a sense of responsibility. So, during the Tournament, she could offer him some tips or help in a more discreet way, which could change the dynamics of how the Tournament unfolds for Harry.
The relationship could start with mutual curiosity. Harry, as Lord Black, is a novelty in the wizarding world, and Fleur wants to know more about him. They might exchange letters at first, getting to know each other's thoughts and ideas.
They might develop a complex relationship. Maybe Harry, as Fleur's master, has to guide and protect her. It could be a relationship based on mutual respect and trust, with Harry using his skills and knowledge to help Fleur in various situations.
In this fanfiction, Harry would grow in his understanding of different magical cultures. Fleur is from Beauxbatons, and through their relationship, he gets to know more about the French wizarding world. Fleur would develop a deeper understanding of Harry's complex past and the weight he carries. Their relationship would be a journey of mutual discovery. Harry would learn about the allure and grace of the Veela heritage through Fleur, and Fleur would learn about the true meaning of Gryffindor courage from Harry. They would both become more well - rounded characters as a result of their secret relationship.
