It was a beautiful sunny morning in Tokyo; blue sky and white puffy clouds rolling by. The air was humid and warm making it perfect humidity. People were outside doing their laundry or having their breakfast.

"Come on Mikasa! We're gonna be late!" Erin yelled sternly. Her best friend was usually the organized one so why was she being so slow? Usually she was the organized one who kept her from getting into trouble.

"Would you relax? We have plenty of time to get to school" Mikasa sighed heavily. Geez her best friend was so childish. But there were times when her immaturity could be rather cute.

Erin Yeager aged 16; was a very energetic free spirited young woman. While labelled as the Tomboy of her year she was still very popular. She was also very cute and the most desired female after Mikasa.

She was just so optimistic and playful that it was endearing and cute to other people; sadly nobody had the balls to confess to her because they were scared of her personal bodyguard.

Mikasa sighed heavily; she knew why her best friend wanted to get to school so bad. It was so she could sneak into Levi sensei's office before class. She could never understand why Erica was so obsessed with her uncle.

He was quiet, bossy and always sitting at his desk working. In class he had a very cold look and made sure nobody messed around; in her eyes he was a miserable arse git.

"Did you remember your lunch this morning?" Mikasa asked firmly. She knew Erin had a crappy memory so she had to help out with some things. Luckily Erica was capable of cooking so she was capable of feeding herself and preparing meals.

Erin pouted crossly "I'm not a child Mikasa; I can look after myself" she muttered crossly. She hated it sometimes how much Mikasa babied her; sure she wasn't exactly a genius but she was not stupid.

Her father Grisha Yeager was always away on business helping sick people or running his clinic; she got used to being alone and looking after herself. Over the years she had become quite independent.

Her mother had passed away from an illness when she was 13; her father still missed her dearly but was glad to have his daughter to keep him going. Erica remembered her mother fondly and when she thought of the way she had been before her passing; her heart broke.

"Well I'm just making sure; if not for me you'd forget to eat" Mikasa scolded crossly. There had been days where Erica had been in such a rush she hadn't had time for breakfast at all. This caused her to sometimes pass out or become weak upon attempting to perform a task; no matter how easy it was.

"Hey; that's not true!" Erin hissed crossly. Sure she wasn't exactly an early bird like Mikasa but she had a good morning routine; it was easy to remember and kept her organised.

Suddenly they heard calling and Armin hurried up behind them; he lived in a different neighbourhood but always met them on the way to school. He was a meek, quiet boy but was very friendly and good natured.

"I'm gonna go on ahead; see you guys later" Erin said quickly dashing off. Now that Armin was here she could use this opportunity to sneak off to see Levi-sensei. Nobody knew of her feelings for Levi but that was because they wouldn't understand; they would judge her and get mad.

Mikasa sighed heavily as she watched her best friend go; they had been raised as sisters but she loved her as a woman. However Erica would never see her that way; her heart only wanted Levi.

She often got jealous of how precious her uncle was to Erica; she only wished she could mean as much to her as he did. She never seemed to understand everything she did was because she cared.

Armin looked at her sympathetically; he knew how much she loved Erin but her feelings went unnoticed. While he could support Mikasa deep down he knew you couldn't force love; so it was just another step she would have to deal with.

He took her hand gently and squeezed it supportively; she was like a sister to him as he was an only child. He would do anything he could to make sure she stayed on track and didn't feel alone.

Mikasa smiled gently and squeezed his hand back; Armin was a good friend to her and she appreciated his support. Without him she would be a mess and most likely sobbing into a tub of ice cream every night; Thank god for good friends like him.

Meanwhile at school

Erin rushed down the hallway as fast as her legs would go; she didn't care if she got into trouble she just had to see him. Eventually she reached his office and slammed the door open wide.

"Good morning Levi-Sensei!" Erin cried nervously her cheeks flushed and panting heavily. Her body was buzzing with energy after running so fast; she felt like she could do or say anything right now.

Levi Ackerman aged 30; a handsome young man who was a very quiet and distant individual. His only known friends were Hange-Sensei and Petra-Sensei; two female teachers around his age. He was always seen with a cup of tea and a book; sometimes he would have a sweet snack on him but it was a rarity.

Levi looked up from his book; he wasn't happy about being disturbed but had grown accustomed to it. While Erin annoyed the hell out of him sometimes; she had an endearing personality.

"For a brat you're awfully loud in the morning" He muttered crossly sipping his tea. He often wondered where she got all her energy from considering she was always so active.

Must be all those hormones that started activating once a female reached her prepubescence; However he did feel sorry for that monthly problem she would have to face. It was a curse he did agree was very unfair to women even if it was preparation for childbirth in the future.

Erin pouted crossly "I just came to see my favourite teacher; why are you being so mean?" she mumbled sulkily. She really loved Professor Levi; he was unlike any person she had ever met before.

While most adults ignored her or babied her; he scolded her but also treated her like a person. She felt safe around him; all of her troubles no matter what they were seemed to vanish.

Levi peered at her quietly from his book; his gray eyes roaming her figure quietly. He did often find himself stunned at her well proportioned body and luxurious long legs. Never in his life had he seen such a stunning young woman before; while he had many girls giving him love letters the only one he had eyes for was her.

However his moral code and common sense stopped him from acting on those desires. He would never attack a young girl like her; but sometimes the urge to take her was very strong indeed. Her piercing green eyes filled with mischief; her flowing brown locks, her perfect breasts and those legs...god those legs.

Erin tilted her head to the side quietly her eyes gentle "I worry about you sometimes Levi-Sensei". He was always working with piles of paperwork in his desk; with the amount of tea he drunk it was most likely to keep him going.

Whenever she had to study for a test she would drink caffeinated beverages too; it keep her going in order to get more work done. However it only worked for a certain amount of time and she had to rebuke it.

Levi raised an eyebrow quietly; she was worried about him? Wasn't she in the middle levels of her glass grades? I mean she wasn't exactly an idiot but her grades could be better.

However when he asked Mikasa about it she always said that Erin took her studies very seriously but pushed herself a little too hard sometimes so she ended up burning herself out.

Erin smiled fondly "You're always shut up at your desk all day; your drink so much tea to keep you going. Every time I visit you always have so many papers piled up its never ending..." she explained concern in her tone.

She would often overhear other teachers saying that Levi rarely gave himself a break and was always making sure all his work was done. It was no wonder he was grumpy and pissed off a lot; he must have been exhausted.

Levi turned to her surprised; she always acted so cheerful he never realized she was so concerned about him. I mean his friends teased him or messed with him about it but never really did anything. But this girl was always visiting him to make sure he was ok?

Erin saw him staring at her and blinked; why was Sensei staring at her like this? A cheeky smile then spread across her face "What's wrong Sensei? You haven't fallen for me have you?" she teased playfully.

God he was so cute; more so because he was never honest about how he really felt or about what he was thinking; thus making him easier to mess with.

Levi clicked his teeth and turned away hiding his blush; there was no need to worry about that he already had. But the fact that she was teasing him about it pissed him off; she really was still a brat. But a very very cute brat; hell a fucking adorable brat at that.

Erin slid off the window ledge and wrapped her arms around his neck happily; It made her so happy to think that Sensei liked her too. Her long brown hair tumbled across her shoulder and tickled Levi's cheek; he breathed in quickly holding himself back.

"You're so cute Sensei; just like a little kid!" she teased laughing in amusement. He was so adorable when embarrassed; and only she could see him like this. It was her special secret that only she knew about sensei.

Levi grumbled crossly hiding his growing blush "Damn brat" he muttered crossly under his breath.
