Okay so this will be a AU modern day Helsa story with eventual Kristanna.

Elsa is going to absolutely hate Hans at first, but she will grow to like him over the course of the story.

**Anyone who does not like this pairing then PLEASE DO NOT READ!**

So the plot is...Anna is going to sneak to Hans' birthday party against Elsa's wishes. Elsa is then going to find out after Kristoff (Anna's best friend reluctantly tells her) and then they follow after her. Later that night Hans will experience a home invasion, which will have the four of them trapped inside with three crazy psychopaths and Hans is going to be forced to play the hero.

This story will contain some violence, sexual innuendo and will involve alcohol use. I may even increase the rating to M later.

Anyway If this story gets enough interest then I will continue.

Chapter One.

"What the hell is this?!" Elsa fumed as she threw the piece of folded paper at the auburn haired man, as he breezily strolled to his dorm room.

"Whoa, snowflake. Isn't this a little past your bedtime?" he taunted, glancing at his watch.

"I said, what is it?"

Hans held his hands up in defense. "Chill out babe. It's just an invitation to my birthday party."

Elsa took in a calm, inward breath. "I'm quite aware of what it is Hans, after all, I can read."

Hans was confused at her flustered demeanor. "So, what seems to be the problem then?" There was a momentarily silence before Hans offered up an explanation. "Oh wait," he teased. "Are you jealous because I invited your sweet little sister along too? Do you have a problem with sharing Princess?...or were you hoping to have me all to yourself?"

"Pffft, as if!" Elsa retaliated in a mocking tone. "No Hans. You see, my problem is the obsession you seem to have with my sister."

Hans raised an eyebrow. "Obsession? Actually, I would prefer to call it a healthy interest. And since I don't seem to be getting anywhere with you. I thought she'd be the less complicated option."

Elsa tensed, resisting the urge to punch him. But as she didn't agree with, or promote violence, she settled for shooting him a steely glare instead. "My sister is off limits. Do you hear me?! I know how your dirty mind works, Westergard. Anna, is not going to be one of your trophy's, or another one of your conquests, and she is certainly not going to be another notch on your bedpost."

As he moved dangerously closer to the blonde-haired beauty, leering at her, he couldn't help, but admire her slender body, and those soft, luscious curves. Yet, he could also sense her fear and trepidation, it was overpowering. As he extended his hand to stroke her hair, he whispered softly, "oh, that is a pity, But then again...I was rather hoping it would be you I'd have pinned to the bed... your royal iciness."

The lust in his eyes disgusted her. How dare he! "In your dreams Westergard!" she growled.

"You're always in my dreams, Elsa," Hans purred as his body rubbed up against hers. "Would you like to know the kind of fantasies I have about you, snowflake? They're enough to make a nun blush." His emerald green eyes glittered with ectasy as they became level with her blue orbs, their noses almost touching. He realized he had her trapped against the wall, with no-where to go. Well it's not a bed...but it certainly will do.

Elsa felt her anger rising. He was tormenting her, and for some strange reason, he seemed to be enjoying it. "You're sick... deluded and I hate you!"

"And why is that, Elsa? Is it because," a hungry glint crossed his eyes as he discreetly placed a hand on her thigh, moving it slowly upwards, "I know how to warm that cold, frigid, ice cavern of yours."

Mortified at his overzealous, perverted mind, Elsa raised her hand and slapped him hard across the cheek. "You disgust me!" she spat, before pushing him aside with all her stength, and stomping off down the hall.

I may have deserved that. Hans gingerly rubbed his cheek, it sure hurt, but not as much as his bruised ego. "So I guess this means you're not coming to my party then?"

"Ugh! that man is so infuriating," Elsa hissed later that night as she was curled up on her bed sharing chocolate with her sister. I mean the audacity of that leech, thinking that he has any kind of chance with me...or you."

"Yeah, so infuriating," Anna repeated almost dreamily. "I can't believe you hit him though."

"I know, and believe me, it wasn't intentional, but he is so insolent sometimes. He deserved a lot worse," Elsa replied bitterly.

Anna placed another piece of chocolate in her mouth before adding, "It was still kind of nice of him to invite us to his party though. No-one's ever invited me to a party before. And he is rather cute."

Elsa threw her hands up in exasperation. "Have you not been listening to a word I've said?"

"Don't be such a drama Queen, it's just a party! and I happen to like parties."

"Whatever you're thinking Anna. Don't think about it. Hans Westergard is a disgusting pervert and you will stay away from him...understand?!"

Anna recoiled from the sudden sharpness in her sister's tone, unconsciously shifting away from her. "So you're not even going to allow me to make my own decision about whether I want to go or not?"

"Anna, please? We all know what happened the last time I allowed you to make your own decisions. You ended up being trapped in a snowstorm for three days, and you almost died."

The young redhead grimaced at the thought, before countering with her own response. "But I didn't."

"That's not the point. If it wasn't for those two volunteers, Gerda and Kai, and their very smart dog Olaf, finding you when they did. Then you could have very well frozen to death."

That fateful day, three years ago still plagued the young blonde's mind. She had given Anna her one night of freedom, and she had come so close to losing her sister...forever."

"I know you're just trying to protect me. But it's just a party, Elsa. What could possibly happen to me at a party?"

"Quite a lot actually. Especially with a crowd of alcohol, drug and hormone fueled party animals."

Anna was enraged at her sister's obvious distrust. "I can take care of myself! God! you're such a buzzkill, Elsa. Maybe, you really do need to get laid."

Ignoring her sister's wayward behavior, Elsa mustered up a cold, harsh voice. "Enough Anna! We're done talking about this."

"So, that's it then, your final answer. End of discussion."

"Yes," Elsa replied curtly.

Anna huffed. "Fine then. I'm going to bed."

Great! She hates me. Way to go, Elsa.

The very next day, and much to Hans' surprise, Anna appeared before him, smiling.

"Hans, I accept your invitation."

"What did you just say, Freckles?"

Ignoring Hans' pet name for her, Anna repeated herself, with slight elaboration. "I said, I accept your invitation...you know, to your birthday party this saturday."

He stood there, grinning. "So, I guess her royal iciness couldn't resist me after all?"

Anna knitted her eyebrows together, looking puzzled. "Huh?!"

"I just said, I knew Elsa couldn't resist coming to my party. It's going to be such a blast."

"Actually Hans...I hate to burst your bubble, but it's just me who'll be coming."

But you're so ordinary. "Well isn't that just fabulous." A few drinks later and I'm sure she'll succumb to my sexy charm. Elsa was preferable, but it looks like I get the next best thing. "So Anna? How in the world did you get your sister to agree to let you come?"

"Well..." she admitted, tucking a stray strand of hair behind her ear," she doesn't actually know I'm coming. You won't tell her, will you? I mean, it's just that she'd freak if she knew I was going behind her back."

Hans sneered jubilantly, patting her head like a dog. "Of course not, Freckles," he promised as he flashed her a dazzling smile.

"I can't wait," Anna giggled, beaming with excitement

Neither can I. After all, what her royal holiness doesn't know..won't hurt her.
