Well, perhaps Fleur rejects Harry for some reason. Maybe she's still in love with Bill and tells Harry she can't be with him. This would leave Harry heartbroken as he might have developed deep feelings for her.
It could be that Fleur is under some kind of spell or obligation that forces her to break Harry's heart. In the wizarding world, there are many dark magics that could be used to manipulate relationships. For example, a love potion gone wrong or a dark wizard's curse that makes Fleur act out of character and break Harry's heart.
In this fanfiction, it might be that Fleur has to leave to protect Harry. She might be in danger herself and by distancing herself from Harry, she breaks his heart. Fleur is a strong and independent character. She could be involved in some dangerous plot that requires her to sacrifice her relationship with Harry for the greater good. This would leave Harry heartbroken, not understanding why she has left him.
He might become withdrawn. Harry has been through a lot in his life, and being heartbroken by Fleur could make him retreat into himself. He may avoid his friends and isolate in his dormitory at Hogwarts.
One possible plot could be that Harry and Fleur run away to escape the chaos of the wizarding world. Maybe they go to a far - off land where they can live in peace and explore magic on their own terms. They might discover new spells and magical creatures together.
In such a fanfiction, the plot could be extremely complex. Harry would have to navigate the different personalities of Fleur and Tonks. Fleur is proud and confident, while Tonks is more down - to - earth and adaptable. Maybe the story could start with Harry forming a deep friendship with both of them during the war. As they face different threats together, their relationships deepen. Eventually, they realize their love for Harry is more than just friendship. And in this unique world, they come to an agreement to be with Harry, which could lead to a new era in the wizarding world where the three of them work together to bring about changes, like better relations between different magical communities and a new way of teaching magic at Hogwarts.
One interesting plot could be Fleur and Harry teaming up for a dangerous magical quest that was previously thought impossible. They could use their unique magical skills, like Fleur's Veela charm and Harry's Parseltongue ability, to overcome various obstacles.
The plot could start with Harry unexpectedly coming across the Potter ring. Then, his encounter with Fleur might be by chance. As he wears the ring, he starts to notice changes in his magic. Fleur becomes interested in these changes and they start to explore what the ring means together.
Well, perhaps the marriage contract was made with an evil wizard. Fleur has to figure out a way to protect herself and her family. She teams up with some of the Order of the Phoenix members who are also interested in the ancient magic involved in the contract. They research in the Hogwarts library and other secret places to find a way to nullify the contract. In the process, Fleur also has to deal with the wizard who is trying to enforce the contract and his minions. This could lead to some exciting battles and tense moments.
Well, in fanfiction about the House of Potter, Fleur's rise could start from her initial encounter with the Potter family. She might initially be seen as an outsider, but as time goes on, she earns their respect. Her beauty and magical abilities are obvious assets. However, it's her loyalty and ability to adapt that really make her rise. For instance, she adapts to the British magical society's ways while still maintaining her own identity, and this makes her an important part of the House of Potter in the fanfic world.
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.
Fleur could use her Veela charm to try and disarm or distract vampires. Since Veela have a certain allure, it might work on vampires as well.
I'm not sure specifically as there could be many different versions of such fanfiction. But it might involve a secret relationship or adventure between Harry and Fleur that wasn't in the original books.
