Disclaimer: I don't own any characters from The OC. Song used for this one is All We Know by Paramore from their album All We Know is Falling.

A/N-Okay, it is pretty much summer for me now (I still have four exams to go, but I'm going to pretend that it's already summer despite this) and this means I have way too much time on my hands. I need something to do, so what do I do? Crazy me, with a little help from my beta Meg, came up with an idea for a 100 song challenge. I put my iTunes on shuffle and the first 100 songs that played I wrote down. I have to write a oneshot about each one. The rules are: Each oneshot has to be at least 1500 words and contain one line from the song somewhere in there. So yea. This is the first one, 99 more to go. So look forward to reading 100 random Seth and Summer oneshots. Just to make this note even longer, this first one kind of has angst, but they won't all be like that. I guess it depends on the song. They will also all be unrelated, so what stands in this one may not be the same for the next one. It's just easier to post them all in one story than to have to post 100 separate stories. Also, just to make this more fun, feel free to guess the line that I used from the song. Wow, so I'm just going to wrap this up and say thanks to Meg for being willing to edit 100 oneshots!!

All We Know by Paramore

Summer sighed. She didn't want to do this. She didn't want to leave again. Didn't want to leave him again. But it was what had to happen. It was what they needed.

It was what she needed.

It wasn't that she didn't love Seth. She did. Everyone could definitely attest to the fact that she did.

It was that she needed more in her life. She couldn't keep living her life as she had been. Sure it had been a great way to go about life for a while. She had a routine, a daily schedule that she always followed.

She was tired of it though. She didn't want to get up everyday at the same time and do the same things. She needed change. Change that she wasn't getting by staying with Seth.

She didn't necessarily want to leave him permanently. But for now, it was necessary. She was pretty sure that this would help them in the long run. Maybe, if they were truly meant to be together, it would make their relationship that much stronger.

She folded another shirt and placed it gently in the suitcase. She looked around her. Everything that she wanted was packed into the suitcase now. It was hard to look at, to think that this time tomorrow she would be long gone.

She sighed, shoving the suitcase underneath the bed. She didn't want him to know what was going on. She wasn't going to tell him. She was just going to leave. He would understand.

She walked into the living room of their apartment where he was sitting playing Playstation. The ninja game, it was his favorite. He liked to play it sometimes to unwind from a long day. She sat down on the couch next to him and watched him play for a few minutes before he turned to look at her.

"Hello my little Summer. I didn't even know that you were home."

"Uh, yea. I got home early today. I was just taking a nap," she said softly.

"Long day at work?"

"Mhmm."

"I'm sorry." He put the controller down and moved closer to her, softly rubbing her shoulders. "Feel any better?"

"Mhmm." Summer could just feel the tears coming out of her eyes. She didn't know if she could leave him. She had to though. She couldn't just sit there in this routine life anymore. She needed more.

"Sum what's wrong?" Seth questioned. "You're a lot quieter than you normally are after a long day of work. Normally you bitch about all the people you have to deal with."

Summer smiled slightly. "I just…it was a long day. I don't really want to talk about it."

"Okay," Seth said. "What do you want to eat for dinner? Do you want me to cook something up or do you want to order from some place?"

"Can we order some Chinese food?"

"Of course."

"I'll go get the menu."

"Okay."

Summer leaned back against the pillows closing her eyes. Every moment she was spending with him made it harder for her to leave. She had to remind herself that she needed more.

She watched him in the kitchen for a few minutes as he searched through the drawers for the menu. She heard him humming softly to himself, like he did so often but always denied doing so.

She was going to miss him so much.

She almost walked right back to their room. She almost walked away from getting more in her life.

She didn't though. She needed to do it. As much as it was going to hurt him and her, she needed to do it. She knew it was going to be better for them.

She really hoped that this was going to hold true. If it didn't, then she was about to make the worse mistake of her life.

Summer looked over at Seth. He was totally into the movie that they were watching. Summer could barely keep her eyes on the screen. She kept on changing her focus to look at Seth.

It was her last night to spend with him.

She had such difficulty wrapping her head around this fact. She didn't want it to end. But it was her decision.

He didn't even know that it was their last night together. He thought that it was just another night together, nothing special about it.

She almost wished that he knew the truth. Then they would be doing something. Something other than sitting there watching a movie that they had seen at least five times already.

She hated herself. She was being purely selfish. She should spend the night with him how he wanted to.

She sat there for a few more minutes as they watched the movie, Seth mouthing the words along. Summer rolled her eyes. She couldn't handle this movie anymore.

She inched closer to Seth, wanting less space between them. She touched his arm gently so that he would refocus his attention on her. As soon as he did, she brought her lips to his.

"Whoa, where's this coming from?"

"I've lost interest in the movie. I want to do something else."

Seth looked from her to the movie a few times before turning the movie off. "You win. We've seen the movie a lot before."

"Good," she smiled, grabbing his hand. They walked to their bedroom, for the very last time.

Summer looked at him. She was staring deep into his eyes, he was doing the same thing.

He knew.

He knew she was leaving.

She didn't know how he knew. But she could tell he knew.

He pushed the sweaty hair out of her eyes so that he could look at her eyes even better.

"You're leaving aren't you?" he asked softly.

She nodded her head slowly, the tears spilling out of her eyes.

He closed his eyes briefly, not saying anything. Then he rolled onto his back so that she could no longer see his face.

"You never said this wasn't what you wanted."

"I know. I just. I need more. More than this."

"More than this?" Seth sighed. He tried to not show how much he was hurting but he couldn't help it.

Summer could see that he was hurting. She wanted to do something to take away his pain. She wanted to show him that she still cared about him, that he still meant a lot to her.

She kissed him again. For a few minutes he returned the kiss and they were slowly losing themselves in each other. Then Seth pushed her away.

"What are you doing Summer?"

"I'm sorry. I'm just trying to show you that I still care."

"What, you think that fucking me is going to show me that? Do you honestly think that? God, Summer."

"I'm sorry." She couldn't help the tears that started to spill out of her eyes.

"If you wanted to show that you still care and love me then you wouldn't leave me."

She shook her head. "I can't stay anymore Seth. I just can't. I need to get away. I need to get more from my life. I can't just stay here with you forever."

"Can't I come with you?"

"Seth. I need to get away. I feel like I've lost everything that really matters. It's just been you and me and that's it. Our daily routines have taken over my life. I need more. You've always known that I needed more."

"I know," Seth shook his head sadly. He wasn't going to cry in front of her as much as he wanted to.

"I love you. A lot. I might come back. You never know."

He pulled her into him. She buried her head into his shoulder. She was going to miss this so much.

"If you promise me you'll come back, I'll wait for you," he whispered softly in her ear, his warm breath tickling the side of her face.

"I can't promise that I will though."

"I'll still wait for you," he said.

"Don't. Don't go ruining your life because I need something more than just being with you."

"I wish that I could give you that something more Sum. I really wish that I could."

"I wish that it could all be more for me."

They lay in silence for a few minutes, just listening to each other breathe or in Seth's case, listening to Summer cry. He couldn't handle this. He didn't understand why she was leaving if it was making her so sad at the same time.

But deep down he knew that she needed it. She had been distant for a while. She hated her job, their apartment, the place they lived. She needed a change.

"You know I'm serious about waiting for you right?" he whispered, breaking the silence.

"Don't wait for me Seth. It could be forever before I come back."

"I don't care. I'm going to wait for you. Okay? Don't doubt that for a minute."

Summer nodded her head. "Seth…I'm sorry--"

"Sh. I don't want to hear it. Let's just go to sleep."

"All right."

She waited until she was certain that he was asleep. Then she slipped out from his grasp. She got back into her discarded clothing then pulled her suitcase out from underneath the bed. She gave Seth one last kiss on the cheek before leaving him behind.
