Mikasa

She landed on the ground a bit wobbly before leaning on her legs for support. Sweat dripped down her brow while she evened out her breathing. Across from her, her sparring partner silently waited for her to catch her breath. When she looked up, their gazes met, but neither of them turned away.

She wasn't sure if she should ask, but it had been on her mind since these training sessions had started.

Not once had she ever voiced her curiousity, because she thought it was normal for a superior officer to individually train their subordinates. It also wasn't unusual for Mikasa to be shown favoritism. Most of the others teased her about her special treatment, but some people, like Eren, seethed with envy.

For that reason, she never mentioned her private training sessions with Captain Levi to anyone. By her observations, he didn't seem to be speaking others about it with others, so she just decided to follow his lead.

However, the other day when she asked Hange Zoe how often he train with other soldiers, she had laughed in her face. She told her that Levi never trained others individually. Ever. Not even his teammates had ever received one on one training from him. Levi had apparently never offered to teach anyone and always denied those who approached him.

Yet, it had been over two months since the first time Levi had approached her.

"Captain Levi... May I ask you something?"

"Sure", he replied with a raised eyebrow.

"Why are you doing this?"

His shoulders tensed for a moment, but he didn't immediately say anything. He took his time, as if seriously thinking about his answer. Mikasa didn't let herself look away as his gaze remained unwavering, as if searched her eyes for something. "And what is it that you think that I'm doing?"

She thought her question had been obvious.

"Training me."

He closed his eyes and let out an exasperated breath. "I see."

Levi

It had been almost a year since he had first noticed her.

She was still a soldier in training, but she was hard not to notice. The name, Mikasa Ackerman, had been in circulation ever since she first joined the military. She was instantly singled out by her instructors as the trainee with the most potential. And true to their expectation, she was ranked number one in all categories. He wasn't even surprised to learn that her name was mentioned largely amongst the men because of her appearance.

When he had first seen her with his own eyes, he was more impressed with her natural abilities as a soldier than her exotic beauty. She was attractive, he could admit to that, but that wasn't what made him pay attention. It was the way she moved. He'd never seen a trainee move so effortlessly in their maneuver gear, or cut down Titans with that kind of speed and accuracy. She was observant of her surroundings and everything she did was efficient.

It was easy to see why she had piqued the interest of so many.

However, Levi didn't bother to make her acquaintance. Trainees who ranked in the top 10 of their class usually joined the Military Police. A girl who looked like that was probably looking for an easy life behind Wall Sina, not a hard life that was constantly at risk of dying and loss. And with that, he vowed to never think twice about her.

This vow lasted until the Battle of Trost.

She had some kind of familial relationship with Eren Yeager, the boy who could transform into a Titan. Of course, Levi didn't know this at first, so he assumed they were a couple. He made sure to keep conversations with Eren brusque and to ignore his ever permanent shadow, Mikasa Ackerman. It was annoying how often they were spotted together. And despite his efforts to remain indifferent about her, he couldn't help but to silently agree when others gossiped about her being too good for Erin.

It wasn't actually until Levi carefully watched the two interact, that he realized everyone's assumptions on there being any romantic involvement, was false. They didn't share any meaningful looks, there were no lingering touches, and most notably, Eren never got jealous. Mikasa may have felt something stronger than family ties to Erin, but he saw her as nothing more than a sister.

With this new discovery, suddenly Mikasa Ackerman became a person of interest to him. He found himself watching her whenever they were in the same vicinity. The more he watched her, the more he found himself wondering what kind of person she really was. It had been a few months since he had read her files... Actually, he had done more than just read them, he had practicaly memorized them. Yet, he had never actually spoken with her directly.

So from that moment on, he made it a personal mission of his to run into her as often as possible.

She was always polite, but didn't speak much more than basic formalities to him. It reminded him that she just saw him as a superior officer. For his plan to work, she needed to be able to speak comfortably with him. What could he do? How was he going to go about this? When was she ever alone? Would he ever get a chance to speak with her? Have her acknowledge him without the formalities as her leader?

Since when did Captain Levi of the Survey Corp, the strongest soldier humanity had ever seen, obsess over an 18 year old girl?

Almost a week later, he found himself watching as she practiced with her maneuver gear in the twilight of the moon. There wasn't much light shining through the branches, but Mikasa was sailing through the trees as if it was as clear as a cloudless afternoon. He was so entranced, he didn't notice when she had changed course and was heading towards him, sitting in the shadows of a condensed area of branches.

When she dropped down and asked if there was anything she could do for him, he instead offered to teach her how to improve her striking form.

She didn't take him seriously at first, but when he explained the theory of continuous rotation while using maneuver gear, her undivided attention was focused on him. This was a first for him. Mikasa Ackerman had never watched him so intensely before. She usually looked past him, as if eager for anything else to catch her attention. But in that moment, it was as if nothing else was in her field of vision except for him. It was both exhilarating and addictive.

So from that night on, he would search her out when he knew she was off duty and they would train together. Always alone. And always away from prying eyes. She never once questioned his motive, so he never thought to explained what he was actually doing. That is, until she asked him why.

"I don't bring you out here, away from everyone else, just to train you."

Her eyebrows knit together in confusion. "Then why do you always appear when I'm about to train?"

He was mildly surprised that she didn't notice that he only approached her when she was alone. He thought she was more observant than that.

"You're a smart girl, I'm sure you'll figure it out eventually."
