A/N: Hey Guys! So I love the Mortal Instruments series, but Isabelle and Simon are by far my favorite characters! I think they are so cute and when I looked for fanfics about them here I didn't see as many as I thought I would! Hmph . So I decided to write one about them because they are just so perfect together! Hope you enjoy!

Disclaimer: I do not own the Mortal Instruments series or any characters mentioned in this fanfiction. Also, the chapter titles are song titles, so I guess I don't own those either :P

Chapter 1- Dreaming With a Broken Heart

Girls are confusing. They do one thing and the next day act like it never happened. They say one thing and mean something completely different. Simon Lewis wished they were straightforward, but they were a complicated species that he failed to understand. Simon lay in his bed staring up at the ceiling. The clock on his nightstand said 2:02 am; yet he felt wide-awake. He knew his restlessness wasn't due to his nocturnal instincts, considering he'd pretty much mastered those. Nope. It was all thanks to maybe the most confusing girl ever, Isabelle Lightwood.

Beautiful Isabelle Lightwood. Beautiful and spontaneous as a firework. She burned like the brightest star in the universe. She was crazy, loud, smart, witty, and kick ass all put into one very pretty girl. Simon felt nervous just thinking about her long black hair; the way the silky curtain flowed and swayed when she walked in her proud, Isabelle way. Her dazzling smile would have sent his heart beating fast if it still worked.

Simon thought about that night in Idris, where he had seen the real Isabelle. Not the tight dress clad, stiletto boot and makeup wearing Isabelle. She had been wearing no makeup, her hair wasn't done, and her clothes had been simple. He thought he had never seen her more beautiful. That night, they had kissed at first, but as the night went on, she just cried softly in his arms as he comforted her. He doubted not many people had seen Isabelle Lightwood crying weakly in someone's arms, with no makeup and no 1000 inch heels on.

It was the first time she hadn't seemed intimidating or overwhelming. Just a normal girl with normal problems (well not exactly normal problems). She had let him see through her cold, and very thick wall. She had spilled out her heart to him, letting him into the most secret parts of her very secretive mind. And he thought things would be different after that night, but the days following were pretty much the same. Sure they began casually dating, but maybe he didn't want to look for someone to casually date. He had thought that night together would make things a lot less casual.

Simon turned over, flustered. Weren't the girls supposed to be the ones laying awake in bed till 2 and wondering, "why won't he call me?". Weren't they supposed to be the ones begging their boyfriends to get more committed and the guys were the ones who didn't really want something serious. Well in Simon's case, it was reversed. He was the one laying in bed wondering, "will she ever call me?". He was hoping things would get serious. He was the one wanting to see into her soul and blah blah blah.

Simon just couldn't stop thinking about Isabelle freaking Lightwood.

Isabelle tossed and turned in her bed. She flipped her pillow over numerous times, pummeled it till it was the prefect fluffiness, kicked the comforter off and pulled it back on. Nothing worked. She closed her eyes tight and thought of shoes and dresses and rainbows and meadows and parties. But in the midst of all that, Simon Lewis's smiling face would pop into her mind and block all the other things out.

His deep, dark eyes and adorable smile mocked her. His dark, wavy hair laughed mercilessly at her. Isabelle groaned aloud and put her face in her pillow. Her heart pounded as the moment from a few days ago popped into her head. They had been sitting together, their faces inches apart. He started to say something. "Isabelle, can i-," and was then cut off by Alec and Co. bursting through the elevator doors. Can I what? Can I kiss you? Hug you? Drink your blood? The possibilities were endless.

They hadn't seen each other since. It had been three days. No call. No text. And Isabelle as infuriated. Not at Simon, though, at herself. She was Isabelle Lightwood. She did not sit helplessly waiting for a boy to call. Boys called her and she had it no other way. They gawked and drooled and did whatever she said. But not Simon. Then again, Simon wasn't like most of the boys she dated. He was nerdy, sweet, smart, and funny. Yes, he was a vampire and their relationship would piss off her parents, but he wasn't just any vampire.

Isabelle looked at her phone. There was a text from Alec and a call from Jace, but she didn't want texts and calls from them. She considered throwing her phone against the wall but though better of it. Suddenly, it started buzzing loudly in her hand. She sat bolt upright when she saw the name on the screen. It was Simon. She waited for it to ring a couple of times so she didn't sound desperate and tried to sound tired when she answered so he wouldn't think she had been up waiting for his call.

"Simon?" she said.

"Hi, Isabelle. Did I wake you up?" he asked on the other line. Her heart fluttered at the sound of his voice. This was very unlike her.

"Um, y- well no, not really," she said.

"Oh, good. Isabelle?" he said.

"Yeah?"

"Can we meet somewhere to talk?" Simon asked. Isabelle's heart pounded as she fiddled with a stray piece of thread on her comforter.

"Yeah, why?" she asked, trying to keep the excitement out of her voice.

"We can talk when we meet. How about in Central Park?" he sounded urgent.

"Oh, well, okay," she said curiously.

"Ok, good. See you," Simon sounded relieved then she heard him hang up.
