This idea of a story got to me a few weeks ago when my Tumblr page started flooding with Jack/Elsa fanart. Now I'm obsessed with them, and they are probably near the top of my OTP list, so thanks Tumblr, for ruining my life (in a good way)

Anyway, I could not get this idea out of my head so here I am at 5 a.m. writing this. I know not everyone ships Jelsa, but I do and I just had to write this down before I went insane.

I've only seen Frozen once so far (But I've seen ROTG multiple times), so I apologize if not everything is on point. I've done my best to research things along the way while writing this, however, so hopefully I didn't mess anything up.

I don't own anything. Disney and DreamWorks own Frozen and ROTG respectively.

So...I hope someone out there will enjoy this. (I'm kind of scared of posting this, but oh well)

:)

"I wish you'd stay,"

Elsa sighed and nuzzled her face into his cold chest after she said those words. The feel of the chilly bed below their bare bodies complemented their own form of heat as they tangled in the soft blue blankets together. She closed her eyes as she felt Jack move his hand to gently stroke her hair.

"I know," he sighed. "But I have to go. It's against your rules."

"The kingdom's rules," she corrected him.

Jack chuckled softly, pressing his cold lips to Elsa's forehead. The light of the midnight moon spilled all over Arendelle, shining ever so lightly through the curtains of Queen Elsa's bedroom.

"I'll be so lonely," she continued. She really hated being lonely, an all too familiar feeling she didn't want to go through again.

"Your sister will be back from her honeymoon soon," Jack said.

"But it's different. Anna is married now. She has other things to worry about other than spend time with her dear old sister," Elsa said, cracking a small smile.

Jack laughed again, looking down to meet Elsa's sparkling blue eyes. She is so beautiful, he thought to himself, so, so beautiful.

"You could always come with me," he suggested quietly, "I'm sure they would be thrilled to see you again. I even think Sandy has a bit of a crush on you too."

Elsa laughed and wrapped her arms around his torso and said, "I prefer boys of the...colder nature."

"So, Bunnymund's personality? 'Cause that's the coldest thing I've ever had the displeasure of being around," Jack joked.

Elsa laughed softly. "I'm talking about you, Jack."

He just laughed, pressing his lips to her forehead once more. "Come with me," he whispered against her skin.

"I can't. I'm not allowed to," Elsa said quietly.

Jack scoffed to himself. "But you're the Queen. You should have the freedom to go wherever you want!" he exclaimed.

"Apparently not," she frowned. "The castle guards watch my every move."

"Do you want me to do some persuading?" Jack said mischievously, twirling his finger in the air to create a swirl of snow that danced around Elsa's room. "The guards wouldn't mind if a little snow storm followed them around unless they let you out, would they?"

She smiled and laughed a little. "I'm sure they'd be flattered, Jack. But I don't think persuasion would help."

Jack frowned a bit, before his swirl of snow died into the floor. He returned his arm under the blanket to wrap it around her waist and sighed. "If you say so," he said.

"And besides, I have to be here once Anna returns, after all," said Elsa.

"I guess," Jack said quietly.

She nuzzled her face into the crook of his neck, inhaling the oh, so familiar scent of icicles and snowfall, and whispered, "I really wish I could go, though. I wouldn't mind leaving Arendelle for a few weeks, if it's to be with you."

He sighed as he slightly pulled away from their embrace, staring at her for a few seconds as she looked up at him; two pairs of stunning blue eyes connected once more. She was so beautiful, so strikingly gorgeous, so angel-like, that Jack often wondered how a troublemaker like him could ever end up with someone so heavenly. He reached over and tucked a piece of her platinum blonde hair behind her ear and smirked.

"What?" she asked.

"Nothing," he answered, before sighing. "I should really get going now."

"Now? Can't you stay a bit longer?"

"They're expecting me to be there by morning," Jack explained. "I know I can fly fast, but I'm not that fast."

Elsa just frowned.

"I'll be back in a month," he said.

Elsa continued to frown.

Jack sighed deeply before saying, "Look. I won't allow North and Bunny to keep me for more than a month. They just want the five of us to discuss some things, that's all. Plus, we've got the whole world to take care of, literally."

"That's what you said last time," sighed Elsa.

"This time, I promise I'll be back before you even know it, Elsa," he said. "30 days, I swear."

"A whole month," she sighed.

"I'm not liking the idea very much either," he said. "But there really isn't anything we can do."

She sighed deeply and said, "I guess you're right."

Jack really did feel bad. The last thing he wanted to do was to leave the comfort of Elsa's cold bedroom, with Elsa right in his arms, but he was a Guardian. It was his job to protect the children, and to listen to whatever insane thing North had come up with, whether he liked it or not.

"And you," he said, laughing to himself when he saw the messy state Elsa's hair was in. "You need to get some sleep. Don't you have some Queen-ly duties to do first thing tomorrow morning?"

Elsa forced out a laugh. "Yeah."

Jack leaned in and gave her a kiss on the forehead, before moving down to give her a gentle kiss on her soft lips. He really hated leaving her, especially since she was all alone in the Kingdom. With Kristoff and Anna away, and Olaf not being allowed inside the kingdom at night (The maids refused to clean up after Olaf's trailing snow cloud), he couldn't help but feel bad for her, and mad at himself for not being able to do anything about it.

He got out of the bed, and looked around the bedroom for a few seconds to search for his clothes. Elsa laughed to herself as she watched him; the events that happened on her bed earlier got pretty heated for two snow people. After fully clothing himself (His hoodie and pants were thrown on the opposite sides of the room), he walked over to Elsa's side of the bed and sat down at the edge of the mattress.

Elsa, who was still bare naked, sat up on her bed, wrapping her silk blanket over her chest, not like she had any reason to. She looked at him and sighed.

"I hate it when you leave," she said.

Jack smiled half-heartedly. "I'll be back soon."

"A month doesn't seem like 'soon'," Elsa sighed.

"I'll be back in no time," Jack said.

"Still," she pouted.

Jack reached over and fully kissed her on the lips. He swore, he could feel both of their snow turn into heat for just a quick second. After they pulled away, he gave her one more quick kiss before standing up.

"I love you," he said.

"I love you too, Jack," Elsa replied.

"See you in a month," he whispered.

She sighed deeply and nodded.

"Now, get to sleep, your majesty," he teased.

Elsa rolled her eyes but she couldn't help but smile.

After he gave her one more kiss on the top of her head, she watched as Jack strode over to the nearest window to grab his magic staff, which was leaning against the wall before opening the window pane, allowing a breeze of cold air to fly in. But neither of them were phased by the instant drop of temperature; the cold never bothered either of them.

He turned around, giving her one more quick smile, before disappearing into the night, leaving behind a small trail of crystal snow.

She fell back onto her bed, staring at nothing but the dark patterns the shadows made on her wall. It was such a weird feeling; everything turned from perfect to loneliness within one second. Of course, she always missed him whenever he had to return to the North Pole to North's Workshop, but she understood that he had things to fulfil around the world, much like how he understood how she had a whole kingdom to run.

Elsa sighed as she snuggled into her blankets, not even bothering to put her nightgown back on. Her bed suddenly seemed twice as big; without Jack, it was almost too lonely to bear. But she closed her eyes, slightly dreading whatever meeting the Kingdom wanted her to attend in the early morning.

Oh well, at least Kristoff and Anna were coming home soon.

The next morning was a rough one. Elsa only had about a good four hours of sleep before she had to get ready. She has always been a very poised and elegant young woman, but the morning showed no evidence of that. She was stumbling all over herself as she took a cold shower, brushed her hair and got dressed. She was beginning to think that Anna's clumsiness had rubbed off on her since she left.

She tried her best to stay awake throughout the entire meeting. As Queen, everyone expected her to be perfect and on point. Elsa's biggest challenge, however, was trying her best not to let her tired eyelids droop.

The meeting was about Arendelle's annual Winter festival, a fun little event where the people of Arendelle were able to have fun and to celebrate the season of Winter. Elsa thought it was absolutely unnecessary to hold a meeting over an event that happens every single year, but the Kingdom's goal was to 'make each year better and better'. And since Elsa did not have to hide her powers any longer, everyone knew that this year's event would simply be the best.

But it was only the beginning of November. No need to rush things on the festival, right?

"Good morning, Olaf," she greeted the little snowman, who was sitting out, basking in the warm sun, as snowmen do.

Olaf looked up and gave his creator that big Olaf-y smile of his. "Oh! Hello there, Elsa. How are you?"

"I'm doing fine, thank you. Are you excited for this year's Winter festival?" she asked.

"Am I ever! It's been my dream to go to a festival, and to eat food, and to play with all the kids, and to listen to the sounds to flutes and trumpets," he sighed.

Elsa laughed. "That's lovely, Olaf. Anyway, can you tell Sven to clean up after his carrots? I want this place to be sparkling clean when Anna and Kristoff return home tomorrow."

The snowman nodded. "You can count on me."

The Queen smiled in thanks before returning back into her kingdom. She sighed to herself as she walked the empty halls. She was use to this isolation, she couldn't deny that. But things could get too lonely sometimes. Jack was away, Kristoff and Anna were away, and of course, her parents are never coming back. But gosh, being alone to the point of locking herself in her bedroom was something she did not want to go back to.

She told herself to just wait it out. Kristoff and Anna were coming back tomorrow, and Jack was returning in just a few weeks.

Before she knew it, she will be with everyone she loves, and everything will be okay...

It took Jack no time to arrive at North's Workshop and into the Globe Room, the heart of the Guardians' meeting place.

"It's about time you showed up," Bunnymund muttered, annoyance evident in his Australian accent.

"Missed you too, Bunny," teased Jack.

"It's so good to see you here, Jack. This is really important," sighed Tooth.

Jack propped up his staff, and floated on his back. "So, what's up? Did I miss something?"

Jack looked around the room, expecting to see the usually bright faces of North, Tooth and Sandy (Not so much Bunny's), but raised an eyebrow when he saw that all four of them were staring at him with the most distinct lifeless expression.

He stopped floating, and returned both feet on the ground.

"What's going on?" he asked, looking specifically at North.

North sighed, and for once, it was as if he couldn't find the right words to say.

"North? Sandy? What's wrong?" Jack asked.

"You may want to sit down, boy," said North.

But Jack didn't move a muscle.

"It's Pitch Black," Bunnymund said from the side.

Jack turned to him, looking at his fellow Guardian as if he had just spoken another language. North, Sandy and Tooth had also turned their attention to Bunnymund.

"Pitch Black?" Jack asked. "What about him?"

The rabbit sighed deeply before looking at the silver haired boy. "He's back, mate."

It took Jack a few seconds to figure out what Bunny just said. He understood, but he didn't at the same time. Back? Pitch Black is back? But that can't be true. He's gone, vanished! The moment he disappeared was meant to be his last! His nightmares ended him...didn't they?

"How?" asked Jack.

"We don't know how...yet," sighed Tooth.

"But wait, how do you know he's back?" asked Jack.

"I saw him, like how I saw him the last time he returned," North answered. His accent was getting thicker as he spoke; that, or Jack couldn't hear properly due to the fear that had just increased inside of him. Jack was not afraid of Pitch, but the fact that he is back out of the blue? Now that was terrifying.

"A-Are you sure? Are you sure it's not just some black dust flying around?" Jack asked him.

North shook his big head and said, "I know Pitch when I see him, and that was definitely him."

"But that's not the only thing, Jack," said Tooth.

Jack turned to look at her.

Tooth looked at the rest of the Guardians, before flying closer to Jack. She set her feet on the ground, and sighed remorsefully and gently said, "We think we know why he's back."

"Why?" Jack asked carefully, unsure whether or not he wanted to hear the answer.

"We think he's back, not only to get you," Tooth started.

Jack raised an eyebrow. "Then who?"

"We think it has something to do with you, with the people you love," Tooth said.

Jack felt his stomach turn when he heard that last part. His heart sank to the pit of his stomach, because he had a strong feeling to where this was going.

Tooth looked at him sadly and said, "But we think it has something to do with Elsa too."

"Elsa? What could he possibly want with her?" Jack exclaimed.

"We don't know," said Tooth, looking at the other Guardians once more. She sighed before turning back to Jack and said, "But we think he's out to hurt her."

Yeah, so that was my attempt at a first chapter. Hopefully, it was alright. I'll still make this a multi-chapter story, regardless though. OTPs, why must you ruin me like this?

Please let me know what you think of the story so far by reviewing!

Thank you :)
