DISCLAIMER: I do not own Harry Potter; I just use its characters to write (hopefully) interesting stories.
I am actually combining several ideas I have seen on this site, and adding in some of my own.
Some of the language in this will be much softer that what the person would really say, but that is because of yours truly. (Me)
The Letter
Hermione Granger took at deep breath and tore open the letter giving her N.E.W.T. results, to her surprise a golden badge fell out at her feet, she wondered is Hogwarts had sent her a new Prefects badge, but the name on it was Head Girl. She screamed in delight and jumped up and down, until she read the attached letter. The letter informing her who the Head Boy would be, she knew they would have to share a common room with , she hoped with every fiber of her being that it wouldn't be him. But it was: Draco Malfoy. She started at the name and willed it to change, but the eleven black letters remained dooming her.
Draco Malfoy rolled out of bed three hours later and saw a letter with the Hogwarts crest sitting on his shelf. He ignored it for a minute and went to admire himself in the mirror. "I'm so sexy" he thought. He flexed one last time and walked over to the letter, his reflexes being much better than Hermione's, he caught the badge effortlessly. Head Boy,he read smiling, that smile turned into an evil smirk when he saw who the Head Girl, A.K.A. who he would be sharing his dormitory with, would be: Granger.
"Hermione, please tell me you're joking!" Ron Weasly cried, his voice cracking at the end. He didn't want to think of Malfoy being so close to Hermione for a whole year.
"Do you really think I would joke about this?" Hermione asked, sounding close to hysterics.
"Hermione," Harry Potter began slowly, "Don't the Heads have to share a dormitory?"
"Of course not, Harry! They share a common room!" How could he be that dense? The thought of having to share a dormitory with ferret boy made her stomach churn.
"He's a git! He'll probably hex you when you're asleep!" Ron continued. "I don't think you should do this, get out of it!"
Hermione glared at him, wiping tears out of her eyes, "Do you really think I'd give up being Head Girl for the likes of him? And he is a git, but I doubt even Malfoy would attack someone when they're asleep"
"Sorry to interrupt, but-" a drawling started but Ron had jumped up angrily "What do you want Malfoy?" He had his wand pointed at Malfoy, who seemed less than threatened.
"Manners, Weasely, manners," Malfoy looked at the wand pointed at his face as if it were nothing more than a random twig, "Besides, I'm not here for you. Your little girlfriend has to come with me, the Heads need to ride together for instruction."
"Don't!" Hermione whispered, for Ron and Harry looked about ready to murder Malfoy. Hermione got up prepared to follow Malfoy but he did something surprising, "Ladies first" he said he told her in a silky voice and gestured for her to go ahead of him.
He saw her get into the compartment with Potty and Weasel, she had outgrown her bushy hair, it was tamer now, falling to the small of her back in soft curls, her teeth were smaller, and she had matured into a delicate, petite woman. Her eyes had always been beautiful, very expressive, almond brown. The thought that he had her to himself for a year made him smirk; he wanted her to be his alone. What made it easy was the fact that the prejudice about muggleborns had evaporated, not that he really liked them to start with. He moved his way to her compartment just in time to her…her defending him?
"…I doubt even Malfoy would hex someone when they're asleep!" He knew this would be a perfect time to butt in.
"Sorry to interrupt, but-" Weasel cut him off, "What do you want, Malfoy?"
"Manners, Weasely, manners," He said in his most condescending voice. He merely raised an eyebrow when Weasel shoved his wand at him. He was really going to rub it in now.
"Besides," Malfoy sneered, "I'm not here for you. Your little girlfriend has to come with me; the Heads need to ride together for instruction." He knew of course that Hermione didn't return Weasel's feelings; she whispered something to Weasel that he didn't catch. "Ladies first" he didn't do this to be gentlemanly; he did it so he could rub it in more. As soon as Granger passed him he smirked at Weasel. "You know, I think I'm going to like a year alone with your girl, Weasel." He looked down the hall at her with a look he knew would really mess with Weasel. Smirking again he followed Hermione.
The meeting consisted of telling the new prefects their duties, Hermione requested to return to her compartment when it was over, but Professor McGonagall flatly refused. They had to be where prefects could come in if they had any trouble, Hermione wouldn't have minded this but there was only one bench in the compartment meaning she had to sit next to Malfoy. She bit her lip and considered standing the whole way, but there was a good three hours left until they reached Hogwarts.
"I'm not going to hex you, you know," Malfoy said, as if he read her mind.
"Why should I trust you?" Hermione queried with malice in her voice.
He raised his eyebrow in a superior motion. "You told Potty and Weasel you didn't think I would." She blushed, not knowing he heard that and sat down as far from him as possible, which wasn't really far at all. The train motions were making her tired, she closed her eyes. The next thing she knew Malfoy was shaking her awake.
"Sorry, did I fall asleep? Are we there already?" Hermione asked, completely disoriented.
"For a little while, but no, we aren't there yet. I thought you'd want to change your robes first." She looked at him suspiciously; he'd never done anything remotely nice to her before, so why was he acting like they were best friends all of a sudden?
"Why are you being so nice to me?"
"We have to live together for a year, can't we be civil?" He responded as if it was the most obvious thing in the world.
"We aren't living together Malfoy," she making a face, "we're just…living… closely…"
He shrugged and walked out to change himself.
Hermione had fallen asleep on his shoulder, he smirked down at her sleeping form, he liked the way her soft body felt against him. He was fiddling with her chocolate curls when he heard the compartment door open.
"Hermione? I was doing rounds and though I'd come say-" Weasel stopped when he saw Hermione leaning on Malfoy, his hand in her hair. "What the-?"
"Quiet Weasel, you'll wake her up," Draco gave him one of his best smirks and toyed with Hermione's hair more. Weasel glared at him, he was so mad he could barely talk.
"What do you think you're doing? Get your hands off her!"
"No, I don't think I will thanks, I'm quite comfortable." Draco smirked even more when Hermione's hand moved up and rested on his chest. Draco put his arm around her waist. "You see Weasel, I have no intention of letting you getting your slimy hands on her."
Weasel was about to retort when Snape yelled at him from down the hall, "Weasley! Go do your rounds or go back to your own compartment and leave the heads alone!"
"Yeah, Weasel, run along now." Draco sat in bliss for the next two hours with Hermione resting on him. There were three reasons why he was going to make Hermione his, one: he wanted her, he's wanted her for so long, two: it would annoy the crap out of Weasel and Potty, three: he wanted to prove he wasn't like his father, he didn't support Voldemort and he couldn't care less about blood purity. She's mine, he though before waking her so she could change.
