One idea could be a story where Fleur tries to subtly show her feelings to Hermione through acts of kindness, like leaving her little gifts. It could start with Fleur realizing her crush when she sees Hermione's intelligence during a study session in the library.
It could be developed by having Fleur first struggle with her feelings internally. She might be confused because it's not a common type of attraction in the wizarding world. For example, she could write in a diary about her feelings for Hermione.

Well, if Hermione has a crush on Fleur in the fanfiction, it could make things really interesting. For example, it might create some jealousy among her friends, especially if they don't understand her feelings. Ron might be really confused and a bit put off, since he has his own complicated relationship with Hermione. Harry, on the other hand, might be more understanding but still a bit surprised. And it could also change how Hermione approaches her studies and her role in the wizarding world. She might be more distracted, or she could be inspired to be more like Fleur in some ways, like being more confident in social situations.
Well, one plotline could be that Hermione tries to impress Fleur by excelling in areas she thinks Fleur would admire.

There could also be a plotline where Fleur is initially put off by Hermione's attention, thinking it's just some strange Hogwarts behavior.

I'm not aware of such a specific fanfiction.
