Author's Note: HOLA! This is my fourth fanfiction, and it is based on the new movie The Duff. I just saw it in theaters and absolutely loved it. I feel it fits great with the personalities of the Mortal Instruments characters, so there you go! Reviews are appreciated and encouraged. Love you all!

Disclaimer: I don't own mortal Instruments, or The Duff.

Third Person

Jock. Weirdo. Mean Girl. Band geek. Loner. Goth. High school is flooded with labels. They are used to categorize, define, and ultimately, segregate us. In a world of technology and evolution, there is no surprise that these labels have branched out from the originals. Now, there is that one group, that one friend in every cliché that never had a name. The sweet, approachable, average student that you saw, but never truly knew. These are the Duffs. The designated ugly fat friends. Make no mistake in thinking they had to be ugly, or fat. They were just the friend that blended into the background.

Every group has one, and this is the story of one Duff and her journey to self-discovery, no matter the obstacles. Her name was Clary Fray, duff.

Clary-Duff

As I drive to school in my torn jeans and gaming t-shirt, I think about my latest painting. I had been working on it all weekend, while my best friends, Isabelle and Maia went to Kaelie Thorn's party. I was never one for parties, despite who my besties were.

I arrive in my beat up beetle, with its mix-matched paint and scratched windshield. As I drift through the halls, I go unnoticed, as always. I shove all my books into my locker and as I make my way to homeroom, I am flanked by my partners in crime.

There's Isabelle, fashionista, sweetheart who can also kick your ass with her high-heeled boots. Her waist-length black hair and piercing blue eyes demand attention, even if her tall, willowy frame doesn't. That is definitely not me. Next, we have Maia. She's sporty and spicy all the same. Her sun-kissed skin and chocolate eyes and hair that fall in ringlets down her back make her the picture of beauty. Not to mention her toned body and tall height. Yup, not me either.

At a whopping 4'11, with red frizzy locks and dull green eyes, I am nothing like my outgoing, party attending friends. Not to mention, my complete lack of social skills, especially when it came to my crush, Sebastian Verlac with his tumbling black hair and deep black eyes. Every time I attempted to speak to him, it came out a series of stutters and mumbles, then me running away awkwardly. Yeah, needless to say, I wasn't dating anyone.

"So, Clary, what are you going to do for homecoming?" Maia asks, eyeing my attire.

"OHHH! I have major plans," I reply.

"WHAT?! A DATE! LITTLE CALRY'S GROWING UP!" Isabelle shrieks, catching the attention of all our classmates, teachers, and probably the population of China.

"Yes, a date, with Leonardo DiCaprio and all his movies known to man," I reply wistfully as I watch Izzy deflate.

"Clary!" she groans as I make my way into class.

"No," I simply say, knowing the crap she is about to pull about me attending this school function. Before she can say anything else, I catch sight of gold. I immediately know from where. A boy in the back of the class, currently being eaten alive by his strobe light, on again off again girlfriend, Kalie Thorn, grade-a bitch.

Name: Jace Herondale

Occupation: Football Captain

Label: Jock/Man-whore

Relation: Life-long neighbor/grade-A pain in my ass.

We have lived right next to each other since birth and everything was great until he turned 13 and started football. Let's just say puberty hit hard and before I could bat an eyelash, he had a girl on his arm every other minute, and he went from sweet Jace to meathead jock. I inwardly sigh as I sit with my friends, averting my eyes from the massacre Kaelie is doing to his lips. Oh, how can I forget about the Queen Bitch, I mean Queen Bee herself.

Name: Kaelie Thorn

Occupation: School Mean Girl

Label: "Hottest Girl in school"/ Ultimate Bitch/School *Cough, cough* slut

Relation: UH, UH! I steer clear from her. I just observe, from a far. VERY FAR!

When she finally detached herself, she takes a long look at Jace's bored expression and then cracks her hand over his cheek. His face barely changes as she stands and walks out of the room, hips swinging. He sighs and shakes his head to himself as he picks up conversation with his group of football buds. When our teacher walks in, my jaw goes slack. His hair is spiked and black. His ivory skin is smooth and his cat-like eyes are outlined in black. He shimmers as he sashays in and plops down in his seat.

Name: Magnus Bane

Occupation: Best teacher ever

I walk up to his desk as he greets me grandly.

"Why Clarissa dear! You're in my class this year?"

"Yup, advanced English is my calling," I reply sarcastically. He chuckles and motions for me to grab a seat before he take roll call.

I sit with Isabelle and Maia as Mr. Bane reads off the names of my oblivious classmates. As my friends discuss fashion and makeup, my eyes dance over the small cliques within our homeroom, and my first period class. Smarties bent over a large book, cheerleaders jammering like squirrels on crack, loners being alone (obviously), and the football faction obnoxiously shouting about this Friday's game, Jace among them. At this exact moment, he decides to turn his head, golden waves ruffling.

He shoots me a dazzling smile and winks. I just roll my eyes at his stupidity and shift my gaze. He has been "flirting" with me since we entered sixth grade. It doesn't help that we used to take baths together as babies and small children before we began to ask certain questions. That was just the spark to lifetime jokes with that one.

Before I know it, Isabelle and Maia are off to their first classes and I stay in my seat, preparing for English. I sit back in my chair and close my eyes, hoping to catch a few moments of quiet before the official start of the day.

They only snap open when I hear a chair scrape against the tile floor and a body collapsing into the seat directly beside me.

Oh, hell no! I think as I see golden eyes staring into my green ones.

"Hey C, aren't you supposed to be getting to class," Jace inquires, pulling a binder from his leather bag.

"I am in class," I reply, muttering dip-thong under my breath.

"Tsk, tsk. I am not a dip-thong; I am a dip-shit. There is a difference!" he replies. I just scoff and look over at him.

"Well, I'm glad you finally admitted it. The first step to solving your problem is admitting it," I think of my mom's 'motivational' speeches from one of her seminars.

"Good to know," he finishes, smiling at me. I sigh, knowing he isn't going to move his seat, so I grab my bag and begin to gather my things when his voice stops me.

"The other seats are already taken, so I guess you're stuck with me," he smirks, without looking up from his paper. I look around to find he is right, I'm sure that's new for him, and there are no more seats. I groan and throw myself down into my seat with Jace chuckling to himself. This is going to be a long year.

Note: There you go! This is just kind of an intro to the Duff world and Jace and Clary.

Just going to clear up a few things.

Jace annoys the hell out of Clary, but they don't hate each other or anything.

They are in the same grade, but Jace just didn't know she took Honors English.

Magnus is only like twenty-two, a rather new teacher, and he can still relate to the students.

Maia and Isabelle are uber nice and popular, while Clary kind of just blends in to the background, and that's how she likes it, for now.
