Summary: Modern AU inspired by an episode of Grimm. Natsu discovers it's quite possible that he's obsessed with Lucy Heartfilla.

Pairings: Implied Natsu/Lucy, some brotherly Zeref/Natsu, and general other friendship feels.

YouTube Prompt: A general Fairy Tail friendship tribute to 'Never Forget You' by the Noisettes.

Natsu hated history.

He really hated history.

He was useless at remembering things as it was, he still doesn't remember his brother's birthday or the name of his Maths teacher who had been teaching him for the last three years, so to remember a bunch of important dates, and all the facts surrounding them, and then remembering to argue some sort of stupid point about them.

And don't get him started on the while analysing sources.

It all went over his head majority of the time and he was so going to fail this class and disappoint his Dad and big brother.

Fuck, he hated history.

And yet, he loved being in class.

Because he sat behind her.

Lucy Heartfilla. The prettiest girl he had ever seen, the weirdest person he had never known, his best friend in the whole world (after Happy, his pet cat, Lisanna, and Zeref), and she had steadily become the girl he keeps wishing to kiss.

He can't help it!

Everything about Lucy was so awesome and nice. She was kind to everyone, even to the dirt-bags that used to bully her when they were younger, she was so weird with her need to read and study and have privacy and worry over every single exam or bit of trouble they got into, she even liked weird boring books and music and food, and then everything about her just distracted him endlessly.

Her odd scent which was mix of flowers, sweet things, and fruit thanks to the conflicting perfume, shampoo, and body wash she used. He liked to stand behind her and take a deep sniff to breathe it all in. Lucy tended to elbow him in the stomach and tell him off for invading her personal space which was such a weird thing to say because he caught her sniffing him a couple times too

Her hair was all shiny and golden, and always catches the light, especially in History, and Natsu liked to pull at it and feel her silky locks slip through his fingers. He doesn't like how Lucy always smacks his hands away whenever he reaches out but her pink flush of anger and the spark in her eyes drew him in closer.

He's started to kick her chair again in class just to see that cute flush of anger in her face. Lucy was just attractive when she was angry as she was when she was happy. Not like Erza, Erza was just terrifying.

These days Natsu wanted nothing more than to pull Lucy onto his lap and kiss her senseless but since he couldn't do that (not without being kicked in the face, and she has done that when he accidentally grabbed her boob once) he would have to settle suffering an hour of Tudors and World Wars and whatever other crap his History teacher was spouting in order to spend an hour staring at Lucy.

"Hey Natsu," Zeref called out quietly from the door, "Igneel says dinner is ready."

"Just a minute," Natsu groaned, "I need to finish this paragraph."

"It's good to see you're doing your homework properly," Zeref smiled, "I still remember the days you used to copy from Gray mere minutes before it was due in."

"A lot of good that did me," Natsu grumbled, "the icy prick use to give me fake answers."

"Serves you right," Zeref ruffled his hair (Natsu's shove and mumbled 'gerroff' was completely ignored as always), "you should always do your own work and not cheat. What's the subject?" he asked curiously. "I could give help you if you like."

"I thought you said I should do my own work and not cheat?"

"There's a difference between help and copying the answers, Natsu," Zeref's eyes glittered with amusement, "now stop being so cheeky and answer my question."

"The causes of the First World War," Natsu muttered, "I know there's five or four or something but I can't remember all of them and I don't know what to say about them."

"Let's see what you've got so far," Zeref leaned over Natsu's shoulder to read his work, and instantly Natsu knew he did a crap job because Zeref's eyebrow leaped up his forehead in shock. "Natsu," Zeref said in a slow, calm, voice that always meant Natsu was likely to be in trouble, "I didn't realise that Lucy was a cause of the First World War."

"What?!" Natsu choked. "What the hell are you talk…..?" Natsu trailed off as he took in his computer screen with a horrified realisation.

He hadn't written anything good for his homework, no scratch that, he hadn't even written an essay at all, all he had done was written one word over and over again….

Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lucy, Lu

"Fuck!" Natsu swore. "My teacher would so put me in detention if I hand this in!"

"You better start again," Zeref sighed, and then he eyed the computer screen suspiciously, "Natsu," he said slowly, "do we need to have a discussion about obsession?"

"NO!"

Natsu pressed down hard on the backspace button and glowered at the screen. He most certainly did not need Zeref to sit down and explain to him all the ins and outs of being obsessed.

Especially since knowing his luck it would include sock puppets.

And he really didn't need an effing sock puppet tell him that he had an obsession as he already knew that he was obsessed with Lucy

This wasn't the first piece of homework he screwed up thinking about her.

(Meanwhile across town a blonde girl let out an enraged scream as she rapidly pressed the backspace button on her keyboard. "Not again!" she snarled to herself. "This is the sixteenth time for this essay alone. Damn that Natsu! I swear he's doing this on purpose to drive me insane!" she smiled fondly as she thought of her pink haired maniac that both annoyed and thrilled her. That is until she realised she typed the word Natsu again. Damnit!)
