A/N: After finally getting into Attack on Titan, Rivetra is by far my favorite ship. This will be a series of drabbles featuring Petra and Levi, mostly canon. Anyways, I don't own SNK or any of the characters. So please drop a review and enjoy!

Chapter 1: Devotion

"You wished to see me, Captain?" Petra questioned as she stepped inside her superior's office.

Levi stood hunched over his paper-covered desk, his jacket taut around his tense shoulders. He did not turn to face her immediately, unnerving her, but Petra maintained her strict posture. She wrung her hands behind her back as the seconds ticked by. Never had he ever made her wait so long before addressing her.

"Petra," he said, finally turning to face her. Petra immediately noted the dark shadow that was cast over his eyes.

"Shut the door," he commanded. Petra hastily did as he said. Levi turned away until he heard the door click closed. She gulped nervously, wondering what he could have possibly called her into his office for.

"You don't have to look so stiff, Petra. I only called you in here to ask you a few things," Levi said calmly, glancing over at her.

At his words, Petra let out the breath she didn't realize she had been holding. Her shoulders slumped a bit, but she still kept up her rigid stance.

"When I chose you for this squad, you told me that you were going to devote yourself to humanity," Levi said, slowly circling around her. "As well as the squad." His voice was passive, as if he was reciting prose, although his tone remained the same drone it always was.

Levi stopped in front of her, his gaze glaring down at her. "I am assuming that your proposal also includes me as an extension."

Petra nodded, her eyes holding the fierce determination she always had on the battlefield. Levi had been impressed from the beginning by how she was able to switch between being the kind and innocent persona she put on during the day and the fiery passion that she expressed during combat. She certainly was much more complex than she let on.

"Your admiration is valiant, and your loyalty is unwavering." Levi's gaze burned into hers, almost threateningly.

"I swore my heart to humanity, and I do not intend to break that oath," Petra responded solemnly.

Levi nodded in approval. He turned away from her, folding his arms behind him. "I have one more question for you, Petra," he said, staring out the window above his desk. "If the circumstances demanded it, would you sacrifice yourself for your squad mates?"

Petra's breath caught in her chest at his question. He was staring at her now, his eyes demanding an answer. She knew that there was definitely a right and a wrong answer, and that made her nervous. Taking a deep breath, she chose to answer the question as honestly as she could.

"Yes," she murmured, lowering her gaze to the floor. "I have witnessed many of my comrades die unfortunate deaths. But being in this squad, I have realized how much of a family we are here. I…wouldn't be able to live with myself if I wasn't able to save even one of them."

Petra heard him step forward until his boots entered her field of vision. Still, she could not fully bring herself to look up at him for fear that he would reprimand her. She knew very well the issues that existed with choosing between one's moral obligation and military duty.

Petra's eyes widened when she felt the captain's fingers under chin, lifting her gaze to meet his.

"Do not lower your gaze when you are speaking what you feel to be the truth," Levi said softly, although his tone was still stern. "You put your feelings first, even in combat. That could potentially cost you your life, and yet you would still do it?"

Petra nodded. "Yes, I would."

Levi sighed. "As you know, I do not believe in unnecessary deaths. It would be a shame to lose a soldier of your caliber because of something as noble as sacrifice." Levi took a step closer to her, so that they were only a few inches from each other. "But you say that you would sacrifice yourself, for even my sake?"

Petra nodded again, feeling her throat grow dry. "Yes, sir."

Levi's eyes flashed at her sudden use of formality. He noted how much more nervous she was, obviously from his one-sided questioning. Still, she had always been able to handle his presence much better than others. She was brave, and he respected that.

Levi let the silence overtake the room for a moment before speaking again. "Again, your motive is most noble. However, not many other soldiers would be so eager as to disobey orders to save a comrade, let alone save a superior officer." He huffed a breath as he stared at her. "You let your personal feelings get the best of you, Petra."

Petra wanted to squeeze her eyes shut, knowing she could very well berated for her slip in her sense of duty, especially if it was from Captain Levi.

"So," Levi drawled. "I must ask you, Petra, what personal feelings do you have that would drive you to do something as rash as saving your commanding officer?"

Petra's eyes grew to the size of saucers. Was he really asking her that? Her cheeks immediately blushed red, and she tried her best to redirect her gaze, but was then reminded of what he had said earlier. She gritted her teeth, knowing she had no choice but to keep her eyes locked with his.

"C-Captain…" she stammered, utterly embarrassed. Her face burned with shame. She just couldn't bring herself to outright admit what she had been hiding from him for so long, not to his face.

"Tell me the truth, Petra," he urged her. He really didn't want to pull rank on her and order her to speak, but if he had to, he would.

Petra bit her lip and her hands began to shake. Levi could even see the tears that were forming in her eyes.

"Petra…"

"I'm sorry, Captain!" Petra exclaimed, dropping her head into her hands in an attempt to hide her tears. "I-I've betrayed you. I've let my personal feelings distract me from my duty as a soldier. I like you, Captain, more than a soldier should for their superior officer, and so if you have to remove me from your squad, then I will gladly resign."

At her outburst, Levi looked upon her with a mixture of pity and…something else. Petra was startled when he placed his hands on her shoulders, sliding them downward to grab her wrists, encouraging her to lift her head.

"I've known about your affections for a while now, Petra," he said gently. A tiny smirk played on his lips, though she was too distracted to notice it.

"W-What? You have?" Petra asked, bewildered.

Levi nodded simply. He slowly raised his hand to run the back of it across her cheek, eliciting a soft gasp from her. He gazed at her fondly, tucking a strand of her golden hair behind her ear.

"You think I haven't noticed?" he whispered conspiratorially in her ear, making her shudder.

"But Captain…" He cut her off by kissing her suddenly, instantly taking her breath away.

His hands gripped her shoulders tightly, pushing her back until she met the wall. Petra let out a quiet moan, causing Levi to deepen the kiss, taking the moment to push his tongue in between her soft lips. She felt his hands gradually slide down to her waist, squeezing and caressing her curves. When they finally broke to catch their breaths, Levi's gaze was burning hot with passion. Petra blushed, embarrassed that he was the one giving her such a look.

"B-but military regulations–" Petra tried again, but Levi silenced her with a glare.

"To hell with the regulations," he said roughly, rubbing his thumb over her cheek. "As soldiers, we've signed our lives away to the military. Isn't it about time that we take a moment to actually live our lives?"

Petra was shocked at his insistence. There had to be a major reason why her captain was so eager to dismiss the rules when he was a strict man of military ranking.

"Captain Levi…" Petra was rendered speechless.

Levi shook his head, pressing his lips to her forehead. Moving downward, his nose brushed against her collarbone, bathing her in his hot breath. "I can't promise you anything, Petra. I can't say that we'll both be alive tomorrow or even when the Titans are finally exterminated. But I can tell you that I feel something for you, and I can't imagine life with you by my side," he said seriously, running soft kisses up and down her neck. "All I ask for is your kindness, your heart," Levi took a shuddering breath. "And your love."

Petra felt moisture build up along her eyelashes at his words. She had no idea he harbored such feelings for her, and it made her heart want to burst.

"Cap–"

"Don't," Levi stopped her by planting a chaste kiss on her lips. "When it's just the two of us, call me Levi."

Petra smiled, placing her forehead against his. "Levi, I will love you with all that I have until my very last day."

Levi's eyes widened a fraction as he grazed her lips with his thumb. "Your devotion will never cease to amaze me, Petra," he murmured, giving her the first genuine smile she had ever seen.
