I'm not aware of its popularity. There are countless fanfictions out there, and without specific data on views, reviews, or community discussions, it's hard to say if it's popular.
Since it's a fanfiction, the context could vary greatly. Maybe in the story, Fleur restrains Hermione to the bed as part of a rescue mission gone wrong. They might be in a dangerous situation where Fleur thinks restraining Hermione is for her own safety, like if they are in a place full of dark magic and Fleur doesn't want Hermione to accidentally trigger something. However, without reading the fanfiction, it's all speculation.
She would probably be very angry. Hermione is known for her strong will and intelligence. Being restrained against her will would likely make her furious and she'd start shouting at Fleur, demanding an explanation.
One possible reason could be a misunderstanding. Maybe Fleur misinterprets Hermione's actions as a threat to something or someone she cares about. So, she restrains Hermione to prevent her from causing further 'harm' until she can figure out what's really going on.
In fanfiction, the writers often like to play with characters' emotions. Hermione might be possessive of Fleur because she feels a sense of competition. Fleur is known for her beauty and charm, and Hermione, being a strong - willed character, doesn't want to be overshadowed by her. This possessiveness could be a form of self - preservation in the fictional world they exist in.
One great fanfiction with this theme could be 'Love's Unlikely Path'. It beautifully portrays Hermione's inner turmoil as she discovers her feelings for Fleur. The story is well - written, with vivid descriptions of their interactions and how their relationship develops over time.
There could be a fanfiction where Hermione gets tattoos during her travels after Hogwarts. She meets Fleur during one of these travels. Fleur, who has always been seen as the more glamorous one, is a bit jealous of Hermione's new edgy look. However, as they get to know each other better, they realize that their differences in appearance are just surface - level, and they become good friends. Hermione's tattoos could be a story of her adventures, and she shares these stories with Fleur.
They might have a very competitive relationship. Since both are strong - willed and talented. They could compete in things like magical duels or academic achievements. However, this competition could also strengthen their bond as they push each other to be better. And in times of danger, they would put aside their differences and protect each other like true sisters.
I'm not sure specifically if there's one with that exact title, but it's very likely. Fanfiction writers often come up with various scenarios where characters from the Harry Potter universe interact in unique ways. Maybe in this fanfic, Fleur could be initially envious of Hermione's body language that shows her intelligence and determination, and over time, she comes to admire it as a symbol of Hermione's strength.
One possible plot could be that Hermione, as a Lycan, struggles to hide her identity within the Hogwarts community. Fleur, being perceptive, might notice something off about Hermione. Maybe Hermione is afraid of being discovered and ostracized, while Fleur, having her own experiences with being different (as a Veela), tries to help Hermione come to terms with her new lycanthropy. They could form a strong bond as they both deal with the challenges of being 'other' in the wizarding world.
