A/N: This is from a tumblr prompt and I sort of got carried away so this is going to have more than one chapter (I don't know how many yet).

Prompt: Aubrey and Stacie's families are super rich and do the cliche NYC life where Aubrey's family is all lawyers and accountants and Stacie's is fashion designers and she herself of course models cuz why the hell not with those legs. And Aubrey hates Stacie and Stacie loves to mess with Aubrey and it just kinda follows the messes they get into since they do go to the same school and have the same circle of friends and oh yeah they're sorta into one another.

"Hey, Chlo!" Stacie waved and smiled at Chloe as she walked by their lockers. "Bitch."

"Harlot." Aubrey replied without looking at her.

Chloe chuckled. "I don't understand this thing between you and Stacie."

"What thing? You mean our mutual hate?"

"Yeah, I mean, it seems like you're just doing it out of habit now. When was the last time you had an actual conversation with her?"

Aubrey rolled her eyes. "Why would I have an actual conversation with her? What would we even talk about, how far her legs can spread or how many models she screwed at her last runway show?"

"You have a lot of things in common, Bree, and you know it." Aubrey quirked her eyebrow at Chloe. "I'm just saying, it seems kinda childish that you're still mad at her for winning our 6th grade science fair."

"Her stupid rocket set fire to my stand! It wasn't fair!" Aubrey said through gritted teeth.

"Bree, I love you but you know she would've won anyway. She built a rocket." Chloe closed her locker. "I just think that maybe you should give her another chance, you might be surprised."

Aubrey scoffed and closed her locker. "The only surprise Stacie could give me is mono, and it wouldn't be that surprising coming from her."

They started to walk to their next class. "You'd have to kiss her for that." Chloe bumped her shoulder.

"Gross, I'd rather kiss Bumper."

"Well, I sort of told her we were going to her birthday party this weekend." Chloe bit her lip and looked sheepishly at Aubrey.

"Are you kidding? I'm not going to her birthday party."

Chloe skipped ahead so she could face Aubrey. "Come on, Bree, please? Beca's gonna be there."

"Ugh I don't understand your obsession with Beca." Chloe gave made her best puppy face. Aubrey steered Chloe so she wouldn't hit a group of kids. "I don't think I'm invited either way!"

"You are! She told me I could bring a guest, you're my guest!" Chloe smiled at her.

Aubrey glared at her. "But did she actually say my name?"

"Well…" Chloe twisted her lower lip to the side.

"See, I'm not going somewhere I'm not wanted."

"If I ask her if I can bring you specifically, will you come?" Chloe pouted.

Aubrey rolled her eyes. "If she says yes, I'll go" Chloe squealed and started jumping and shaking her arm. "And you'll owe me big time."

Chloe bounced towards Stacie's locker and leaned next to it. "Hey, Stace!" Stacie smiled at her and put her head inside her locker to try to get her physics textbook from the back. "I was wondering if I could bring Aubrey to your party on Friday."

Stacie turned towards Chloe so fast that she hit her head with her locker door "What?"

Chloe smiled sheepishly. "I asked her to come with me?" Stacie glared at her. "I know, it's a bad idea…" Chloe looked down sadly.

Stacie pursed her lips and sighed. "She can come, I don't care."

Chloe smiled and hugged Stacie making her stumble. "Really?"

Stacie nodded and smiled back. She really liked Chloe and she didn't really hate Aubrey, she was the one with the problem with her. "Yeah, you can bring Bitchsen."

Chloe pulled back and slapped her arm, glaring at her. "Stacie! Please, be nice."

Stacie rolled her eyes. "I'm always nice, she's the bitch." Chloe quirked an eyebrow at her and tilted her head. "Okay, maybe not always. But why do you care if I'm nice?"

Stacie closed her locker. Chloe looped her arm with hers and walked her to her physics class. "Because you're my friend and she's my friend and I have the hope that maybe, someday, we can all hang out together without it turning into World War III."

"So this has nothing to do with a certain little brunette you're trying to snag?" Stacie raised her eyebrows.

Chloe blushed. "She's my best friend and you're Beca's best friend and I just want everyone to get along, is that such a bad thing?"

"Fine, bring her to the party and I promise I'll try to be on my best behavior."

Aubrey looked at herself in the mirror. Her hair was down, curls falling over her shoulders. Her strapless black dress stopped at mid thigh, the pleated skirt flowing out slightly. She pulled on a pair of jeans under her dress and zipped a hoodie on top of it. She carefully tied up her hair and checked to make sure she had all her make-up in her bag. She tiptoed down the staircase and was about to reach the elevator when she heard her dad clearing his throat. "Where are you going?"

Aubrey straightened up immediately and faced her father. "Chloe's."

Her dad looked at her over the book he was reading and raised an eyebrow. "Did your mom say it was okay?"

Aubrey could feel her stomach starting to spasm. She hated lying to her dad, but technically she was going to Chloe's and then to Stacie's party. She just knew her parents wouldn't approve of her going to the party of 'that model you go to school with, I don't understand what her parents are thinking' so she just told her mom she was going over to Chloe's and she'd be back in the morning. "Yes, sir."

He looked back down at his book. "Very well, then. Make sure you're back before lunch tomorrow."

"Yes, sir." Aubrey nodded once and then hurried to the elevator. She held her breath until the door closed behind her and she leaned against the wall exhaling heavily.

She waved at the doorman and walked out into the chilly New York evening. She spotted her driver standing by a couple of cars down the block and made her way to him. He smiled and opened the door for her. "Hi, Benji!"

Benji smiled back at her. "Miss Posen," he waited for her to get in. "where are we going this fine evening?"

Aubrey scrunched up her nose. She liked Benji but he was a bit weird. "Chloe's." He nodded and closed the door.

Chloe's building was only a couple of blocks away but Benji had to drive whenever she went out by herself after 9 pm, and she had already sort of lied to her parents so she didn't want to risk them finding out she had walked. It wasn't that they didn't trust her to take care of herself but her family was one of the richest and most influential families in the city. Her dad was a partner in one of the biggest law firms in the city, he specialized in corporate law and handled billion dollar deals for most of the big investment banks. Her mom was one of the best forensic accountants at the SEC. Rule enforcement was a big deal in her house, which is why she usually avoided sneaking out like this. The thought that she was doing this just to go to Stacie Conrad's party nudged the corner of her mind but she pushed it away. She was doing it because Chloe asked her to go with her.

Benji pulled up in front of Chloe's building and opened her door. "Thanks, Benji, I'll walk back home in the morning."

Benji tipped his hat. "Have fun, Miss Posen."

Aubrey waved at the doorman and walked to the elevator. She had spent half of her life in this building so everyone who worked here knew her as well as they knew the people who actually lived here. She had escaped to Chloe's every time she needed a break from her own parents. Chloe's family was more relaxed than hers, her dad was a venture capitalist and her mom ran a couple of charities. Aubrey's dad had worked on a few deals with Chloe's dad so their parents got along well enough. They had even gone to a few joint family vacations.

She hurried to Chloe's room, waving when she passed her mom in the hallway. She went in and closed the door, leaning against it and dropped her bag. Chloe looked up from her bed and threw her arms up dramatically. "Finally! What took you so long?"

"I had to wait until after dinner to change and my mom had a really long story about something that happened at work." She started to take off all her decoy clothes and let her hair down. "I just need to put on make-up and we're good to go."

Aubrey finished getting ready and turned to Chloe who was fidgeting by the door. "How do I look?"

"Wow, Bree, if I didn't know better I'd say you're trying to impress someone." Chloe smirked.

"Well, if you're going to your sworn enemy's birthday party, the least you can do is look hot." She flipped her hair and smiled cheekily.

Chloe rolled her eyes. "You're ridiculous. Let's go." Chloe dragged her to the elevator. "Mom, we're leaving!"

Aubrey looked at Chloe with a smirk as she bounced impatiently. She looked like she was about to burst with nervous energy. She wished she felt like that about someone. The elevator opened and Chloe shot out of the building, looking around for her driver. He was all the way at the end of the block. They usually waited for him to see them and drive down, but Chloe started running toward him. Once they were seated Aubrey wrenched her arm away from Chloe. "You need to calm down."

"I know, I know. I'm just excited about seeing Beca." Chloe's grin was so wide Aubrey was afraid her face would actually split in two.

Aubrey rolled her eyes. "You see her every day at school."

"Yeah, but we never really do things together outside of school. And Stacie said Beca doesn't really like anyone else that's going to be there, and she's going to be busy hosting, so I'll get to hang out with her. This is my chance to really make her notice me, Bree." Chloe said seriously.

"I get that, what I don't get is why I need to be here." Aubrey said crossing her arms.

"You're here for backup and support in case it all tanks." Chloe said leaning onto her side.

The car stopped and Chloe squealed. "We're here! How do I look?"

Aubrey smiled and fixed a couple of stray red curls. "You look great. Beca won't know what hit her."

The party was at a nightclub Stacie had rented out. Some famous DJ Aubrey had never heard of had been hired to provide the music. They reached the bouncer who asked them their name disinterestedly. Chloe answered and, after a quick check on his list, he let them in.

As soon as they walked into the main area of the club, they heard Stacie making her way to them. "Chloe! You made it!" She was wearing the tightest, shortest red dress Aubrey had ever seen. The top crisscrossed over her breasts, showing off her side, most of her back, and a generous amount of cleavage. Aubrey didn't realize she had stopped breathing until Chloe let go of her arm to hug Stacie. Stacie looked at her and smiled, not as warmly as she had with Chloe, but Aubrey hadn't thought Stacie had the capacity to smile at her so it was a nice change. "Aubrey, I'm glad you could come."

Aubrey couldn't help the look of surprise and confusion on her face. Chloe gave her a pointed look and she tried her hardest to smile back. "Thank you for inviting me, Stacie."

Stacie's smile turned less forced. "I don't think I remember the last time you called me by my name."

Aubrey shrugged. "Yeah, well, you can take it as your birthday present."

"Wow, you're cheap." Stacie chuckled and stuck out her tongue. Someone behind them yelled Stacie's name and she looked over Aubrey's shoulder and lifted a finger. "Ugh I have to go play host but let me take you guys to the VIP area, that's where my actual friends are." She said winking at Chloe.

They followed Stacie to one of the corners where a bouncer was standing. There was a cordoned off area behind him and some people from school and others Aubrey didn't know where standing there, dancing or talking. Beca was sitting on one of the couches by herself, looking like she was considering whether or not to use the little umbrella in her drink to gouge her eye out.

"Yo, Becs, do you mind taking care of them while I go mingle?" She winked at her without Chloe seeing and Beca blushed.

"I'm not your entertainer." She said frowning. "But yeah, I guess they're okay."

Chloe smiled and sat unnecessarily close to Beca. "How are you?"

"Better now. This party sucks." Chloe chuckled. "One would think famous DJs would do a better job."

"One would." Chloe nodded.

Aubrey tuned out of their conversation and looked around. After a bit she found Stacie talking to a group of people. She was smiling and everyone in the group seemed to be hanging on her every word. Aubrey knew Stacie had that effect on people, that power to make everyone around her want to hear everything that came out of her mouth, to be the one she looked at and smiled at. The truth was, Aubrey didn't really hate Stacie, she was intimidated by her and she tended to avoid things that intimidated her.

The guy next to Stacie wrapped his arm around her waist, pulling her close and running his fingers up and down her side. She laughed and pushed him away gently but his hand stayed on her waist. Aubrey was annoyed by this and frowned. She chalked it up to being annoyed by Stacie's general floozy attitude and turned away. She excused herself from Beca and Chloe, who weren't really paying attention to her, and went to the bar to get a drink.

Stacie got away from the group of people she was talking to and looked around. She saw Beca and Chloe talking animatedly and smiled. Beca had had an insane crush on Chloe since she had transferred to their school last year. Chloe had taken a whole year to notice Beca. Admittedly, Beca spent the best part of her first year in the computer lab working on her mixes, and she hadn't had classes with Chloe until this year. Stacie had had to listen to her sighing every time she saw her from across the cafeteria. Stacie would smirk and look in the direction Beca was looking but her gaze always fell on Aubrey.

Ever since the rocket incident, Aubrey had been less than cordial with Stacie. Their constant academic rivalry had only exacerbated it. Stacie liked pushing Aubrey's buttons. She knew the blonde liked being in control and there was nothing Stacie enjoyed more than taking her control away. Stacie looked around for Aubrey. She found her standing by the bar, a drink in one hand and the other hand on her hip. Stacie took her in, from her heels, up her toned legs, to the top of her dress over her bare shoulders, and to her lips, wrapped around the straw in her drink. Stacie licked her lips. She had thought about other ways to take away her control more than once, but she knew it would never happen, Aubrey hated her too much for that.

Stacie sighed and downed her drink. She walked back to the VIP area but she couldn't see Aubrey anymore. She went to the bar and got another drink. She turned around and leaned on the bar. Chloe stood up and pulled Beca to the dancefloor. Stacie laughed and raised her glass at Beca when she looked her way. She looked confused but happy while Chloe jumped around her, her red curls bouncing in and out of her sight.

"What are you doing here all by yourself? It's your party, you should be with your friends." Aubrey slid next to her.

"My friends are a bit busy right now." She nodded her head at Beca and Chloe dancing.

Aubrey smiled. "They're so ridiculous. Chloe can't stop talking about the little midget."

"Hey! Don't call her a midget." Stacie bumped Aubrey's shoulder with her own.

Aubrey chuckled. "Maybe if her best friend wasn't so tall she wouldn't look so tiny."

Stacie scoffed. "Still, there's no need to call her names."

"You've called me way worse things." Aubrey said suddenly serious.

Stacie looked at Aubrey. She was looking down holding her drink next to her leg, her other hand holding her elbow. "Only because you called me worse things first." Stacie grazed Aubrey's hand with her pinky.

Aubrey barely felt it but she sucked in a breath and looked up at Stacie. Stacie gave her a small smile and pushed off the bar. "I should get back." She took a couple of steps away and turned back. "Oh, and Posen? Don't think this means I like you."

"I would never." Aubrey said seriously. They smiled at each other and Stacie walked away.

Aubrey followed Chloe around the cafeteria. They passed their usual table and Aubrey frowned. "Chloe, where are we…"

She stopped talking when Chloe put her tray down next to Beca. "I thought we could eat with Beca and Stacie, today. Do you mind?"

Aubrey opened her mouth. She couldn't say she minded right in front of them so she put her tray down next to Stacie and sat, smiling. "Of course not."

Stacie chuckled, she knew Aubrey was lying. "So, Beca and I were just talking about how country music is dead."

"What?" Aubrey looked like she had just said she was planning to bomb the school. Beca looked at Stacey confused because that was not what they had been talking about.

"Yeah, I mean, who even listens to that anymore? It's one of those things that have become a guilty pleasure. People are ashamed of liking country music." Stacie nodded and took a bite from her sandwich. Chloe was trying really hard not to laugh, she could tell Stacie was doing this on purpose and Aubrey was reacting just the way she wanted her to.

"People listen to country, Stacie. One of the judges from The Voice is a country singer, how much more mainstream can that get?" Aubrey pointed a baby carrot at her. "Taylor Swift started out singing country!"

"Yeah, and then she moved to pop because country is dead." Aubrey groaned. "Seriously though, when was the last time a country artist won one of the major Grammys?"

"2010. Lady Antebellum won record and song of the year." Beca answered immediately and they all turned to look at her. "What? I know music." She shrugged.

"See, 2010 was ages ago. No one even remembers that lady anymore."

"Oh my god, Stacie, Lady Antebellum is a band, not a literal lady." Aubrey wanted to smack her.

Stacie frowned confused. "Well that's a stupid name for a band."

Aubrey rolled her eyes. "Country is not dead. If it was why would CMT even exist?" Aubrey said decisively. Stacie quirked an eyebrow at her. "It's a country music television channel!"

"Ohhh. Well there a lot of things on television that shouldn't exist, Bree." The bell rang and Stacie got up. "Gotta go, it was lovely winning this argument." She bent down and kissed Aubrey loudly on the cheek, winking at Chloe and Beca. "Bye, guys!"

Chloe stared at Aubrey with her mouth open and Beca bit her apple to keep herself from laughing out loud. Aubrey could feel herself blushing furiously. She wasn't sure if it was because she was angry or because of the kiss. She decided it was because she was angry. She clenched her teeth. "Stacie Conrad is the most infuriating human being in the universe."

Chloe started to laugh but stopped when Aubrey glared at her. "Come on, Bree, don't take her so seriously. She's just messing with you."

Aubrey huffed and stood up. "Whatever, I have class."
