She wanted to do something crazy just like she did with Nate, Blair and Chuck when she was younger. She wanted to go away. Chuck and Blair agreed to go. All she had to do was tell Nate.

She knocked on his door at 9 in the morning. It took him a bit to answer it but he finally did. He was only wearing boxers; she had obviously woken him up.

"Good morning!" She handed him a cup of coffee.

He took it but shook his head. "It's too early for me to be up." He walked back to his room, set the coffee on the nightstand and plopped back on his bed.

"Natie! Get up! We're going to the Hamptons." She sat on his back and bounced up and down.

"What? No we're not."

"Yes! Blair and Chuck are coming too. It'll be just like when we were kids. Remember?"

"Serena –"

"Just say yes." She got off him and stood up so he could get a full view of the pout on her face. "Please?"

"That's not going to work." He looked at her and got up. Dammit. "Okay. Fine. To the Hamptons."

"Yay!" She jumped forward and gave him a big hug. "I'll help you pack. We still need to get Blair and Chuck so hurry."

They were in the car when she suggested he let Madeline know. He hesitated but called her anyway.

He was glad it was her voicemail. "Hey Mads. I just wanted to let you know that I'm going to be in the Hamptons this weekend. My phone is about to die and I forgot my charger so I might not be able to call." That was a lie. "But I'll see you on Monday. Bye." He turned off his phone.

"Have you guys set a date?"

"Hmm?" Nate didn't know what she meant.

"For the wedding!"

He frowned. "Sometime in August."

That's 4 months away. She felt a pain in her chest. She was glad Chuck opened the car door and let Blair in at that very second.

They four of them sat in the car. They were reminiscing and talking about all the good times.

After dinner, they went to the beach. They were all a little bit tipsy and all the reminiscing was making them sad more than happy. Serena felt especially nostalgic. "I forgot how much I've missed you guys. You're my best friends. You're my family."

Blair hugged her best friend. "You're our family too. No matter how long you're gone for. I'm going to miss you when you leave on Monday."

Nate's head snapped up. "Monday? That's so soon! When will you be back?"

"I'm not sure. I plan to move soon but it will probably take me a few months. I have some jobs to wrap up."

It was 4 in the morning when Chuck and Blair went to bed. Nate and Serena stayed behind. She got off the sand and held her hand out to help him up. He took it and started to pick up the blanket. "Serena."

She turned around fast, not expecting him to be as close as he was. She didn't dare step away even though her mind was yelling at her to do so. "I'm going to miss you. Hurry back, okay?"

She nodded. The tension was killing her. She wanted to lean over a little bit more and kiss him. Instead she looked down because she couldn't handle how beautiful he was.

He lifted her face up to his and brushed a strand of hair off her face. He couldn't take it anymore. He felt like he was going to burst. But he couldn't do it Madeline. He couldn't throw it away for someone who was always running from him. "I really missed you." He was as surprised as she was to hear himself say it.

She pressed her lips to his firmly and she felt him hesitate for a second before opening his mouth and inviting her in. She wrapped her arms around his neck and he wrapped his around her hips, pulling her as close as he possibly could.

"Me too," he felt her say against his lips. It was just the two of them and nobody else mattered. He kissed her neck and ran his hands up and down her body.

He led her back down to the blanket and they tore off each other's clothes. He pressed his body against hers and they both closed their eyes and he felt her reach down and guide him inside of her. It was full of so much passion and love that it felt like they were doing nothing wrong at all. Her familiar moan still drove him crazy.

They both got dressed and went back inside. He kissed her good night and they went to their separate beds.

The 3 of them were already having brunch when Blair got to the dining room. She kissed Chuck and grabbed fruit. It took her only a minute of watching Nate and Serena to know. "You guys had sex! Didn't you?"

Nate and Serena were both stunned. "Uhh…"

"Oh my god! You totally did! How was it?"

"Nathaniel, I'm proud."

"We're not in high school Blair." Nate snapped and he high-fived Chuck under the table.

"I saw that," Serena said. "Can we just eat in peace?" It was already 2 pm. "We should go soon. I have to meet my agent in a couple of hours."

…

Nate sat in his office on Monday morning. He hadn't seen Serena since they got back to the city but he couldn't stop thinking about her. How could he marry someone like thought he loved when he could have someone he had been completely in love with since he was a kid? But he could never really have Serena, no matter how much they pretended.

He heard a knock on his office and then saw the gorgeous blonde poke her head in. "Hey."

"Hey. I'm glad you came."

"I have to be at the airport in an hour. I wanted to say bye."

"I can't believe you're leaving." He picked up the stapler on his desk and played with it nervously. "About what happened a couple of nights ago…"

"I'm sorry. It was a mistake. I know you have Madeline and I fully support that."

He walked over to her. "What if it wasn't a mistake?"

She knew he had plans. She couldn't be the one to get in between them. Even if it meant losing him, Madeline was the best choice for him. "It was, Nate. You're marrying her. You should marry her."

"Did it mean nothing to you?"

"Of course it did, Natie. I loved you for a very long time. You're still so special to me."

He nodded. "I guess you're right. We've been together for so long. I guess it's finally time to let go."

She felt tears sting her eyes and forced herself not to cry. She just nodded.

He ran his hands through his hair. "Damn. Who knew it would hurt so bad." He gave her a hug. "Bye Serena."

She held on to him for her life. She had to let him go. She was only holding him back. She unwrapped her arms around him and left without another words. As soon as she heard the door close behind her she couldn't keep the tears from coming.
