This is my first Elsanna story, please be kind on me (_ _)

.

"I swear to God that she hates me so much." Anna slammed her locker door while still staring at her test paper. "Who gives a 'D' mark nowadays? It's a conspiracy..."

"Or you're just an idiot in biology." A voice joined in. "How are you doing?"

Anna looked up to her only best friend since third grade. Kristoff had been very supportive in her academic life, especially English and Spanish subject. However, he had a limit in science. He was very lucky that he decided not to take biology this term.

"My situation is grave." Anna handed her paper and she witnessed how Kristoff cringed on the red bold mark.

"My condolences..." He gave a sad look.

"Nah, everyone knows that the 'ice queen' hates Anna Summers." The redhead grabbed her English book and marched to the next class. Thankfully she was in the same class with Kristoff in English literature.

"It's because you keep calling her that." Kristoff provided while trying to keep his pace with Anna.

"Or perhaps because I puked on her favorite dress a month ago. Why science people love cutting a dead frog? I am a vegetarian for crying out loud."

Kristoff smiled a little. The puking accident had been a viral for the past weeks. The most gorgeous biology teacher in Arendelle high got puked by Anna Summers, the captain of Arendelle girl's basketball team. The hilarious accident became a trending topic in twitter since somebody got a live feed when Anna started to barf and how the clueless teacher was approaching her in a very bad time.

"Next time they decide to cut any poor creatures I will... Hey, are you listening?"

Kristoff nodded absently, "yeah. I'm sure that the 'Ice Queen' wouldn't dare to hold any experiments with dead frogs while you're around anymore."

"I still have a D though..." Anna sighed.

"Have you tried to talk to her? I mean... perhaps you can ask for extra assignments to help with your credit or something." He tried to reason.

"She gets the 'ice queen' title not without any logical reason. You know that she is the most gorgeous woman and perhaps the smartest woman I've ever known..." Anna frowned when she was describing her biology teacher.

Kristoff raised an eyebrow.

"I hate to admit it but that's true." She cleared her throat not noticing that her ears had turned red. "Anyway, she is gorgeous and smart, has nice body and such, but she is so cold and mean!"

"Whoa, I agree with the cold part, but mean? I never see her bully anyone." Kristoff cut in.

"Hello? My biology paper?" Anna gestured to her 'D' paper which had turned into a paper ball.

"Having a student who is not so bright in biology doesn't make her mean."

Anna groaned, "Whose side are you on!"

Kristoff giggled, "Forever yours, but sometimes I have to be your logic advocates to even you out."

Anna kept walking while she spotted the source of her frustration was standing on top of stairs. The 'ice queen' was apparently carrying a mountain pile of documents and didn't see her at the hall.

"That's her." Kristoff whispered.

"Yeah." Anna shrugged.

"She seems having a hard time carrying those papers. Should we help her?"

"She is too good to accept any help. Ice queen, remember? A royal teacher." Anna air quoted the word 'royal' with her hands.

"She needs help. Maybe if you help her she would reconsider your 'D' mark. Come on..."

Anna seemed to be evaluating about his reason and her options.

"You know what? I will go to the class first. You help the queen and try to talk her. See you in class."

Anna had been so deep in thought that when she turned her head to see him, he was already gone.

Meanwhile the ice queen was still trying to readjust the pile of documents so that it wouldn't fall off when she descended the stairs.

Then at last, Anna decided that helping her 'ice queen' teacher wouldn't hurt.

Oh and how she was wrong big time.

.

.

The problem was her timing. If she had been fast enough to walk up the stairs and offer her help, this thing wouldn't be happening. Or if she had been quick enough to dodge and run, or if Kristoff (that traitor) hadn't been convinced her to help the 'ice queen' teacher... or simply if she had no stupid reflex (thanks to her basketball practice on catching and throwing balls) this wouldn't be happening.

So that her 'ice queen' teacher was being too confident in descending the stairs with so much baggage in her hands that made the woman couldn't even see where her foot was stepping on and then she tripped. Next thing happened was the teacher went airborne between stairs and flying (or falling) toward Anna.

Meanwhile being caught in surprise, Anna had reacted without thinking. It had been her nature to catch the airborne ball, except that this time, it wasn't a basketball. It was a person, her biology teacher, the most gorgeous and smartest woman Anna ever met but also the coldest and the meanest, Anna hated her, or she was supposed to hate the 'ice queen'. Sometimes though, the redhead had to admit that when she saw the 'ice queen' she knew that she could never be able hate the older woman with all her heart. Now that her biology teacher was flying (or falling, because the woman looked like an angel sometimes, Anna blamed that), everything was flashing in front of her eyes like a kaleidoscope. Anna remembered how they two met and how she took biology class despite she hated the subject.

It's because of her. Elsa Anderson.

What will happen when an immovable object meets an unstoppable object?

So Anna prepared herself to catch her flying (or falling) biology teacher.

.

.

Anna was very sure that no ceiling in Arendelle High had white bright color. Her high school building was blue dominant and some white stripes here and there. She wasn't in school and strangely the first thing that had come up in her mind was how she had missed the English class with Kristoff.

It took few moments until the recent facts filling into her head. Now that she could distinguish the buzzing sounds that came from somewhere around her, the buzzing turned into a telephone ring, weird beeping, people murmuring, rubber shoes on tiles, and several other sounds that Anna couldn't guess what those were. The point was, her head was too dizzy and couldn't take the background noise anymore.

"Miss Summers." Someone called her.

Anna jerked her head in surprise. It was a wrong move since her world suddenly exploded into stars. It sounded a little bit dramatic but she swore she saw stars.

"You should take it easy, Miss. The doctor would come and see you soon." Anna didn't recognize the voice and her head was too hurt to be used for thinking other than how she hated the antiseptic smells. Oh, she was in hospital.

"Wait, she is awake?" Another voice, this time Anna had been familiar with the tone.

"Yes. You shouldn't leave your bed, Miss..."

"Anderson. Elsa Anderson. And I demand that the young woman on that bed to get immediate treatment."

Now Anna's head was getting clear.

"We understand, the doctor is in his way here. Please, go back to your bed."

"I am perfectly fine. That girl is my student and she is possibly having a crack in her skull! Seriously, can you guys act a bit more professional or something?"

Now Anna was listening to the 'ice queen' versus a hospital nurse.

"Maam..." Whatever the nurse was going to say was being cut short by the doctor's arrival.

"Good morning, everyone." Anna detected a stern smile on the man's voice. "Where is the patient?"

Anna heard the sliding curtain and looked up to three people that now were hovering beside her bed. The nurse appeared to be in her fifties, she had this wise yet friendly look (Anna guessed due to experience), the doctor was a young man with red hair like hers but with stupid looking sideburns. Anna was right about the smile, he had this too big smile on his face and perfect aligned teeth along with them. Her doctor was a dentist... perhaps she was here because she knocked her teeth off or something.

"Miss... Summers, I am Doctor Hans." The sideburns doctor took the chart from the old nurse. "I see that you've got X-ray and a cast for broken arm..."

Wait, what?

"You had a bump in your head, I suggest that we take a CT scan just for precaution." He flipped the next page. "Oh..." It seemed that he had found something in her chart that was so interesting.

"Miss Summers, do you remember why you are here?"

Anna was so focused on those teeth that she almost missed the question. "What? Yeah? Maybe? I'm not so sure. The last thing I remember was walking to the English class with Kristoff... where is he anyway? He better not to ditch me here... after that I..." Anna's mind went blank. She swore something had happened but what was it?

"It's alright, you are just in shock. Do you remember this lady here?" The redhead doctor stepped aside so that Anna had a full view on her biology teacher.

"Yeah! Ice queen... Ehem, I mean Miss Elsa... I'm sorry, I mean Miss Anderson." Anna would blame her bump head for not able to speak someone's name correctly.

The blond teacher sighed offering an insincere smile, "You can call me Elsa outside the school."

Anna kept her cool by nodding a little, "Okay... ehm... Elsa?" The name had this funny sensation in her mouth. Anna didn't dislike it.

The doctor cleared his throat, "Miss Summers, let me tell you that you had accident early this morning when you were trying to break Miss Anderson's fall. It was quite a heroic action..."

"I did what?" Anna tried to swing her right arm but then she was surprised when she found a bulk of cast wrapping her entire arm.

"Don't worry, the X-ray result has come in. Your broken arm is a clean break. We just need to keep in cast for at least 4 months..."

"WHAT?!"

The doctor, the nurse, even Elsa were a bit startled by Anna's sudden scream.

"I can't have broken arm! I have an important game in 2 months. Oh crap... This isn't happening."

"I am sorry Miss Summers, unless your 'game' is a chess game you can't strain your arm for awhile. You also need to attend PT after we take off the cast."

Anna buried her head between her knees, "this is nightmare."

"If we have the all-clear CT result, you may go home... and I believe your parent needs to take care some administrative papers before you are discharged."

With that the doctor and the nurse left Anna alone together with her teacher.

"Kristoff went to contact your parent a while ago." Elsa was the first to break the silence between them.

"He shouldn't bother... they were off to Thailand again weeks ago and I bet they are now in super exciting adventure deep in jungle." Anna's parents both were archeologists, it was very usual for her to be left alone in home while both her parents gone to do their job. She had been spending her time more often with Kristoff than her own family.

"Oh..." Elsa seemed to be thinking for a moment. "Well, I guess I will take care the discharge paper later since your parents aren't here..."

"... Thank you." Anna said weakly.

"I am deeply sorry that I fell and crashed into you." Elsa said carefully.

Anna chuckled, "it was not your fault that you crashed into me..."

"What do you mean? It was entirely my fault that I carelessly tripped and fell, injuring my student as a result!"

"... Yeah, you are the blame for trip and fall thing... but it wasn't your fault that I was there and deliberately decided to catch you."

Elsa opened her mouth, ready to counter whatever Anna was going to say but then after hearing the redhead student she fell completely silent.

That moment both women realized that something had shifted between them.

.

.

The doctor declared she was a good to go home on the afternoon.

"So, Miss Summers, your scan has clean results. The bump is only superficial wound. I suggest icing it two times a day until the swelling is down... also, do you have someone to watch you in home? You need to take the painkiller when your arm hurts too much and don't ever think about doing straining things for at least two weeks. I will suggest bed rest for a week to rest your body..." Doctor Hans scribbled something and then handed it to Anna. However, Elsa was the one who took the prescription note.

"We understand. Thank you, doctor." Elsa said shortly.

Anna caught a gleam in Doctor Hans's eyes if only for really short moment when the man looked at her teacher. She understood his reaction perfectly since her biology teacher was too gorgeous even under the hospital's lighting.

"Anna!" Kristoff jogged over when she was heading outside with Elsa.

Anna was thankful that Kristoff had come to her rescue. Elsa had been very quiet along the way and she couldn't come up with any topic to talk with her.

"Kristoff!" Anna wanted to wave but Elsa was faster than her in keeping her broken arm from waving.

"Here, I bought this on a store around here." He took out a snowman sticker from his pocket.

"That's cute!"

"Yeah, I knew you will say that. Here, lemme..." Kristoff put the snowman sticker on Anna's blue cast. "Hey, you picked a cool color for this cast."

Anna frowned, "I didn't. I thought this color came in default..." Anna turned to meet Elsa's gaze which now was back to be unreadable, like her usual persona when she was asking the student to cut the dead frog's stomach and note its bowel's development stage.

"So... where you are going to stay? I've called your parents but keep hitting the voice mail. I have left some messages though that they should contact me whenever they get my messages about you..."

"I'm going home, that's obvious. I'm perfectly able to take care of myself." Anna said proudly.

Kristoff snorted.

"What?"

"Oh yeah, you can take care yourself just fine. However now you just only have one capable arm, what's your plan while showering, eating, or doing stuffs that need both hands participation?"

Anna winced a little imagining how to bath with only just one arm by herself.

"How about you staying over at my place for few days?" Anna offered.

"If you two don't mind..." Elsa who had been quiet when the younger two were bantering finally spoke out.

"It would be rather inappropriate if a guy staying at a girl's place for days. I can't allow that happen as your teacher."

Both Anna and Kristoff exchanged glances.

"I will accompany Anna for tonight since this accident was my responsibility... thank you for your help, Bjorgmann." Elsa said to Kristoff with a final tone.

"... Yes, maam."

"I would also take her home..."

"Wait, I thought Kristoff is the one who will take me home?" Anna was confused.

"He rides his motorcycle here. No way would I let someone with broken arm riding on a backseat of a motorcycle. Beside, I was the one who drove you to the hospital."

"Wait, no ambulance?"

"I didn't have time to wait for cavalry when your unconscious state seemed to be... grave. I asked nearby students to help carrying you to my car and drove you here without getting any speeding ticket..." Elsa explained. There was a joke somewhere inside her explanation but Anna couldn't figure it out since Elsa maintained her serious expression during the conversation.

Elsa walked out first to bring her car while Anna waited at the hospital entrance with Kristoff.

"So... you are going to miss the game this season, huh?"

"Yeah." Anna didn't need someone to remind her of that.

"What a bummer..."

"Yeah."

"So... you are going to spend the night with your 'ice queen' teacher, huh?"

"... uhm, yeah." Anna didn't sure how to respond that.

"What a bummer...?" that came out as a question.

"I-I don't know."

Kristoff just loved how Anna's ears would turn red when she was blushing.

"Give me full report tomorrow. Just to make sure you don't turn into an ice statue or something."

Anna grinned, "... That perhaps I can arrange."
