Well, it could be about some hidden feelings that Harry and Fleur have for each other. Maybe they team up secretly to solve a mystery in the wizarding world that no one else knows about. They might use their unique skills and knowledge, with Fleur's Veela charm and Harry's courage and magical abilities, to face a new threat or uncover a long - lost secret.
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.
One possible plot could be that they meet secretly in the Forbidden Forest. Fleur might be drawn to Harry's courage and Harry could be intrigued by Fleur's beauty and unique charm. They start sharing their secrets, like Harry telling Fleur about his struggles with Voldemort that he doesn't share with others. Their relationship grows as they find solace in each other's company away from the prying eyes of Hogwarts and the wizarding world.
The main characters are Harry and Fleur, of course. Harry Potter is a well - known hero in the wizarding world, known for his defeat of Voldemort. Fleur Delacour is a part - Veela witch who participated in the Triwizard Tournament.
One possible plot could be that Harry and Fleur end up living together due to some post - war arrangements. They might initially have a bit of a cultural clash as Fleur is part - Veela and has her own French - influenced ways, while Harry is very much a product of the British wizarding world. But over time, they learn from each other and become friends. Harry could be teaching Fleur about some of the more unique aspects of Hogwarts' history that she might not know, and Fleur could be showing Harry some of the beautiful magic she learned in Beauxbatons.
It could be that they leave to attend a special magical training that is only available in a very secluded place. They might have received an invitation from a very powerful and reclusive wizard. This training could enhance their magical abilities in ways that Hogwarts or Beauxbatons couldn't. They see this as an opportunity to become stronger and more self - reliant, so they leave together, excited for the new challenges and knowledge that awaits them.
One possible plot could be that Fleur has been influenced by some dark magic or a powerful enemy. Maybe she's being blackmailed to kidnap Harry. She might take him to a hidden location, perhaps an old, abandoned castle. Then, the story could revolve around Harry trying to figure out why Fleur did this and how to escape while also dealing with Fleur's internal struggle about what she's done.
In this fanfiction, the vampire could be an old acquaintance of Fleur from her Beauxbatons days. He was once a student there who got turned into a vampire later. Harry gets involved when he notices some strange happenings around Fleur. The three of them then get caught up in a mystery that involves a powerful dark magic item. They must work together, with Harry using his Gryffindor courage, Fleur her Veela charm, and the vampire his immortality - related skills to solve the mystery and keep the item from falling into the wrong hands.
Perhaps in the fanfiction, there is some sort of magic gone wrong. Harry and Fleur are caught in a magical spell that makes them act out of character. This leads to their relationship becoming more intimate than expected and Fleur getting pregnant. The rest of the story might be about them trying to reverse the spell while also coming to terms with the pregnancy.
One possible plot could be that Harry and Fleur's pregnancy is a result of a magical accident during a joint mission. They initially struggle with the news, as they have different worlds and cultures. Harry is from the wizarding world of Britain and Fleur is from France. But as the pregnancy progresses, they start to discover new things about each other and their respective heritages, and they come together to prepare for the arrival of their child. They might face opposition from some quarters who think their union is strange, but they overcome all odds with their love for each other and the future of their family.
One possible plot could be that after the war, Harry realizes his deep connection with both Fleur and Tonks. Fleur might be attracted to Harry's courage and his role in saving the wizarding world. Tonks, on the other hand, could see in Harry a kindred spirit who has also faced great losses. They could start a relationship where they all support each other in rebuilding the wizarding community, with Harry eventually marrying both of them in a non - traditional but magical ceremony.
Well, perhaps they run away because of a misunderstanding within the wizarding community. Harry and Fleur might have been wrongly accused of something, like stealing a powerful magical artifact. So they decide to flee and clear their names on their own terms. They journey through different magical lands, encountering various magical creatures along the way that either help or hinder them.
