Fleur got jealous very easily and hates things which takes Hermione's attention away from her.
Hermione didn't understand why Fleur got jealous. She didn't really see herself being someone worth getting jealous over. Quite honestly, she believed she had more of a reason to be jealous because of Fleur's veela beauty. The blonde draws people in like moths to a flame and there are obviously better-looking people than her which would be more suited for the beautiful heiress, and yet Fleur is happy with Fleur.
But Fleur got jealous over the smallest of things. She would get jealous of a book which the brunette was reading while the two were sitting on the brunette's bed. She doesn't outright say she is jealous, but her actions and behaviour very much points that the blonde is being possessed by the green monster.
Hermione was sitting in between the blonde's legs with the blonde holding her from behind and she did not think anything of it, her eyes gliding over the print before turning to the next page. She was content just being in the room with the blonde's presence, but she began to realise that the blonde wanted more as she began to make noises behind her. Slight grumbles in French and she swore she felt small, deep growls in her chest while her hands that were wrapped around her waist began to move along her sides, slightly digging her fingertips into the brunette's skin. Not to hurt her but to make the brunette notice her agitation.
Hermione glances over her shoulder to see the blonde's slightly darkened look, looking at her in complexion before turning around to continue reading, unsure on how to deal with the blonde. But then eventually the blonde just cannot stand it anymore and will literally give a whine in Hermione's ear and her hands will reach for the offending object which is taking her girlfriend's attention away from her.
"Hermioneeeee! Pay attention to me! You're dating me, not some stupid book!"
"Fleur!"
Fleur will then promptly toss the book aside and wrestle the brunette to be beneath her and lock her lips to hers, needing a taste of the brunette as she has been deprived of it for the whole period, they were together.
Fleur got jealous over small things, but the one time she truly got jealous was during the Triwizard tournament and it was the time to find dates for the dance.
Hermione was busy reading in the library, doing some homework while also researching for new ideas on how to help Harry perform better in the tournament when the seat at the table where she was sitting at was suddenly occupied than none other the Quidditch star, Viktor Krum.
"Hello Herm-own-ninny." He said quietly, flashing a small smile to her in greeting. Hermione smiled back.
"Hello Viktor."
Viktor would often come to the library, most of the time being followed by his various fangirls. Hermione would get annoyed personally as people came to the library to study and to enjoy the only place with peace and quiet, and the fan girls would not keep quiet no matter how many times they were shushed by others. Luckily, Madam Pince dealt with them rather quickly and eventually Viktor could come to the library unbothered.
Hermione hasn't spoken much with the Quidditch star, but she has come to known him to be relatively quiet. He would often read some Quidditch books or some spell book of some kind near where the brunette would study, the two of them sharing a silent companionship as they read and worked, and Hermione had no ill will towards him.
"Herm-own-ninny." Viktor spoke up again, his features looking kind of soft, well, as soft as they could get with his rather stoic face.
"Yes?" Hermione asked, lifting her head again from the book she was reading. She noticed a slight flush dusting over the Quidditch star's cheeks, a very uncharacteristic thing which the fourth year as seen on the older boy.
"Do you…have a date vor the dance?"
Hermione's eyes widened at the question, not expecting it from him. The Yule dance was something which every single girl in the school has been looking forward to, it being the talk in almost every conversation in the corridor. Parvati and Lavender have been talking nonstop about their potential outfits and hair-dos that they had in mind for the dance. Hermione will admit, she has joined in with a few of their conversations, but otherwise she is usually too spoken out of it, considering with the type of company she has been hanging around lately since dating a certain blonde.
The veela's definitely looked forward to the dance and each time that Hermione visits the carriage, she gets tugged into almost every conversation, the veela's giggling and pushing for answers on what she will wear at the dance. While Hermione was certain that she was going to go with her heiress girlfriend, Fleur has yet to ask her and so she can't say that she has a date to the dance yet, but she is pretty sure that she already does.
"O-Oh! Well…I…um." Hermione started, her cheeks blushing and her eyes looking everywhere but Viktor as she suddenly had a feeling of what he was about to ask. And she was proven right with her theory when Viktor spoke up again.
"Because…I have been vanting to ask…if you'll come to the dance vith me?"
And there it is, the question Hermione had a feel that he was going to ask. Viktor is sweet, despite all the rumours surround Durmstrang and if it were another case, she would most like have agreed to become his date. But considering that she was in fact in a relationship and she couldn't possibly go with anyone other than Fleur, she was put in an awkward position right now as she was trying to figure out a kind way of saying no.
But she didn't have to as someone beat her to it.
"I'm afraid Monsieur Krum," a hand was placed on Hermione's shoulder and the brunette couldn't help but tense at the cool voice she heard behind her, belonging to her girlfriend which Hermione could tell was quite, quite, quite, angry at the moment. "That she is taken for. It is quite obvious that I would be taking my girlfriend to the dance. Don't you agree?"
Hermione paled as she turned around and saw the icy smile which Fleur had on her face. Her grip on the brunette's shoulder tightened slightly and while her face was fixed in a smile, her eyes were blazing very hotly, swirling into a colour of gold, a very clear sign that she was getting very emotional right now and could very much start shifting.
"Oh…I vas not aware-"
"But now you are. So, if you would please, allow me and my girlfriend to spend time together without any unwanted attention. Hmm?"
Fleur was making it very clear that his request was denied and that the brunette was very much taken. He stoically nodded and stood up from his seat, saying a quick goodbye to Hermione before walking off out of the library, rejection laying itself on his shoulders.
Hermione turned to face the blonde, but she let out a surprised yelp when she was suddenly grabbed by the wrist and pulled out of her seat and dragged towards the bookshelves, Fleur walking at a brisk pace.
"F-Fleur! What are you-"
Hermione was interrupted by suddenly get shoved against one of the bookshelves and sandwiched between the hard shelves and a warm body, a leg slipping between her own two legs and lips suddenly pressed to hers, hands cupping her face as Fleur kissed her harshly and passionately. Hermione could feel the jealousy that the blonde was feeling, and she was pushing the feeling into the brunette as she kissed her, making it very clear what she thought about the Quidditch star asking her to the dance.
"You're going with me." Fleur growled the words against Hermione's lips before pressing her lips to hers again, just as passionately as she did before. Hermione just clung to the blonde's shoulders as they kissed, needing to as it was the only thing she could hang on to keep her up as her knees were going weak from the intensity of the kiss.
"You're going to the dance with me." Fleur pressed open-mouth kisses along Hermione's cheek, jaw, and neck, eventually settling on a bit of skin where she began to suck harshly.
"No one else." She growled against Hermione's neck once she finished leaving her mark on the brunette's neck, lifting her head to lock eyes with the younger witch. And all Hermione did was nod.
"I wouldn't want to go with anyone else but you."
And Hermione closed her eyes as Fleur smashed her lips against Hermione's again, rewarding the brunette for her answer while wrapping her arms around her waist to tug her closer.
