One possible reason could be that she was captured by some dark wizards who oppose her and her friends' actions. They might see her as a threat due to her intelligence and magical abilities. Another reason could be related to a misdirected spell or curse. Maybe someone was aiming for another target but accidentally hit Hermione and then tied her up to prevent her from seeking help immediately.
Fleur could be a bit hesitant at first, not fully understanding the situation. But once she realizes the gravity of Hermione's state, she becomes determined. She might call for help from other reliable wizards or witches she knows. Fleur would also comfort Hermione, telling her that she's safe now and that they will find the culprits. She may use her Veela charm in a subdued way to soothe Hermione's distress.
I'm not aware of such a specific fanfiction. Fanfiction can cover a wide range of themes and scenarios, but this one seems rather unusual and perhaps not in line with the general spirit of the original works. However, the world of fanfiction is vast, and there could potentially be something out there that I haven't come across.
One possibility could be a situation where Fleur is under the influence of a dark spell. Maybe she's been hexed to do this to Hermione. In the fanfiction world, this could be a lead - up to a rescue mission by Harry and Ron. They would have to figure out how to break the spell on Fleur and free Hermione.
It could be a case of miscommunication. Fleur misinterprets something Hermione said or did, and in a fit of rage or confusion, she ties Hermione to the bed. As the story progresses, they clear up the misunderstanding and end up becoming friends or allies.
Well, fanfiction involving such scenarios can be a bit of a grey area ethically. On one hand, if it's done in a non - malicious and non - sexual way, it could be seen as exploring different plot ideas within the fanfiction world. However, if it has any undertones of harm or inappropriate behavior, it's not okay. Many people might find it disturbing or against the spirit of the original characters.
Often, there's a theme of friendship and loyalty. Her friends, like Harry and Ron, will usually come to her rescue. And also, the theme of magic. There are often magical elements that are either the cause of her being tied up, like a cursed spell, or the solution to her getting free. In some cases, it can also be about self - discovery. Being in such a tough situation makes Hermione realize new things about herself and her abilities.
It's often for the sake of creating drama. Tying up a main character like Hermione puts her in a vulnerable position, which can drive the plot forward. It makes readers worry about her and wonder how she'll get out of the situation.
The theme of danger and rescue is also quite common. Hermione being in a vulnerable state of being tied up often leads to a situation where her friends or allies need to rescue her. This builds up the tension and shows the loyalty within the group.
One possible plot could be that there is some sort of misunderstanding. Fleur believes Hermione is in danger from some dark magic or a dangerous creature and ties her to the bed to keep her safe. As the story unfolds, they realize the miscommunication and work together to solve the real issue at hand. However, this is a rather strange starting point for a plot and would need a lot of careful development to make it a believable and engaging fanfiction.
