Chapter IV: The Stranger

2 years later...

"A duel?" questioned Mikasa before the boy who stood in front of her. Levi was besides her examining the arrogant tall boy whom, a few minutes ago, had brazenly challenged Mikasa for a duel to be her new partner instead of Levi.

"Indeed a duel," the boy said with a charming smile, "everyone else had to do it as a test to pass the buddy system and have your partners selected except for you two."

The tall boy had aqua-blue upturned eyes, a fine sharp-edged nose, soft medium lips, and slightly tanned skin. His black hair was cut short on the back of his head, while his left side was close cropped until the line of his eyebrows were. His bangs swept, overlapping, towards his right side and hovered softly on is face.

"State your name, brat." Levi interfered, containing an unknown anger to him, while sliding between Mikasa and the strange boy. Mikasa only kept looking at the strangers keen eyes with her usual expression.

The boy gave a wide smirk, showing his white teeth, and saluted.

"Einar Ansgar Castillo from the 105th squad of the Scouting Legion, at your service, Corporal Levi."

Levi's eyes furrowed. "Who authorized you to leave your squad?" Levi paused, "Einar." Einar kept the smirk on his face when looking at Levi though his eyes weren't smiling. Mikasa faintly shuddered as invisible sparks clashed between Einar and Levi.

"Ein!" yelled out Erwin coming from behind him and interrupting the dangerous confrontation. Ein? Levi repeated the familiar name as he watched Erwin smack Einar's back. Einar lost his wide smirk and glanced at Mikasa, startling her a bit by the way his eyes changed.

"Yes, Commander Erwin?" responded Einar with a dark tone in his voice. Levi observed his immediate change in attitude.

"Let's discuss the situation after Mikasa and Levi clean up and rest," said Erwin as he eyed the not-so-clean Mikasa and Levi standing in front of him, "I'm sure they, Levi especially, would like to clean up after coming back from their two week expedition outside the walls."

"Sure as hell I do," Levi annoyingly murmured, walking past them while Mikasa quietly followed behind him. She was stopped by Einar's grip on her forearm.

"Please consider what I said earlier, Mikasa" Einar said with a distant charming smile. He was taller than Mikasa by half a head so when he pulled Mikasa close to him, looking up, she could clearly see the dazzling uncommon eyes he had. Unexpressively, she nodded, knowing he was serious about the duel though deep inside her heart she felt a small prick telling her to just ignore it. Levi was already a good distance away so she went and caught up to him.

All the soldiers around them made way from sensing Levi's menacing aura.

"I won't lose," Mikasa said while taking off her shirt, "it already took me a long while to get used to living with someone...I don't plan on readjusting myself for a stranger." Levi said nothing while drying himself from showering a few minutes ago. They had put up a shoji screen Armin had given them so they would be able to dress when they had finished showering instead of having to wait on each other to finish.

Mikasa had to say those words since he hadn't said a word from having encountered Einar. She could only hear the shuffling of clothes on his side of the room. For some reason, she felt like having another partner besides Levi was just impossible, with the exception of Eren and Armin. She got used to Levi's clean freak methods, his modus operandi on missions, they're everyday rigorous training, his tea breaks, his sleeping habits, his husky deep voice and both of their scents mixed together in the room to produce a sweet aroma.

He was waiting for her, wearing only trunks, when she finished showering. As much as the routine to always check each other for injuries after their expeditions ended, she could not get used to it. It was one of the most dangerous rules they had thought up of, though it was more of a cover up for the one incident in which they saw each other naked. In the end, she couldn't remember who had suggested the rule in the first place so the awkwardness wasn't so painful to bear at that time and moment. However, the procedure always took a toll on the restricted desires they both were accumulating through the years.

She sat down on her bed while he, with an unreadable expression, approached her with the medical kit.

"Lift your arm, Mikasa" he said, sounding more like a command. She slightly frowned at his tone then slowly shifted to allow him access to the bruise on her left arm, under her bicep. "You should have at least let me put some...undergarments." Mikasa said with a non concealed blush, regretting not turning around since his muscular exposed chest was right in front of her face and also regretting only having a towel wrapped around her. She concealed a small flinch upon his touch on the bruise. Here it comes, she thought to herself. The spots where he touched began to burn but not because of pain from the bruise, but because it was him that was touching her.

She tried to concentrate on breathing normally and slowing her thrumming heart in her chest hoping he didn't take notice of it. "It's easier with no clothes to get in the way." he replied as he trapped both of her wrists with one hand and made them both slump back, laying on top of her in her bed. Mikasa was wide-eyed and frozen as she saw him slide his free hand down the sides of her hips, and even lower to her thighs where the towel covered her.

Her breathing staggered as he craned his neck, and his lips touched her neck. A sweet burning sensation bloomed where his trail of kisses went from her neck, to her collarbone, and back up to her jawline. "L-Levi" she heaved as she mildly struggled under his weight. He groaned at her movements.

"Stay still," he breathed besides her ear, sending a shudder throughout her whole body. He then grabbed the bandages that were in the medical kit and tied her hands on the bedpost. By now, her towel was loose and her ivory skin was almost exposed to the predatory look on his eyes.

She knew what they were doing was wrong, that she had to put a stop on it, but her common sense was diminishing as he settled himself between her legs while he caressed her thighs. She wrapped her legs around him and pushed him against her. She heard a slight moan from him as he once again started his kisses on her neck. Her body burned hotter as his hands slithered under the towel and sparks flew as his hand came to contact with her breast. A loud moan escaped her as her back arched and using that levitation, he sucked on her other breast. She gasped as her arms thrashed trying to get a grip on him but couldn't.

"L-Levi!" she moaned louder as his tongue worked wonders on the bud of her breasts. She didn't notice he was no longer wearing trunks until her inner thighs felt the hot and hard member throb against them. Her legs loosened around him as his mouth made way to her navel though his hands were still on her breasts. Mikasa felt intoxicated. She no longer grasped any reason whatsoever and just let loose her inner desires for the man on top of her.

"Untie me." She said looking down at his sharp features. His eyes languidly went up to look at her struggling to untie her hands. She saw a mischievous grin playing in his handsome face as he abruptly and roughly pushed two fingers inside her making her breath a strangled scream. "W-Wait!" she shouted, but he was already pushing in even deeper. Something is wrong she thought as warning signals told her the man she was with was not Levi. With eyes opening wide, she saw how the man's form became taller with less muscle. Glowing aqua-blue eyes pierced her as she was able to untie herself in the panic that was surging through her.

His free hand pushed her shoulders back to the bed but Mikasa resisted setting herself upward and bringing her own hand, curled in a fist, towards his face.

"Fuck!" Mikasa heard someone growl as her eyes snapped open to reveal a sunlit room and Levi laying on the floor next her bed. "What the hell was that for?!" Levi raged as he got on his feet and looked down at her confused face, her arm still in the air from the punch she sent his way. She rapidly scanned the room and realized it was theirs. "When did I fall asleep?" she asked, bringing down her hand. When he didn't respond, she looked up to see his eyes furrowed. "Are you crying?" he asked as he raised his hand to catch a tear falling from her cheek.

She stilled at the brushing of his hand on her cheek. This is Levi she said in her mind. Levi stiffened as he felt her arms wrap around his waist and her head rested on his stomach. She felt his warmth even through the scouting legion uniform he was wearing. His scent calmed her senses. "First you punch me and now...this?" he inquired but his voice held no hostility.

"Levi"

He stayed silent as he felt her slightly tremble and was tempted to hug her back or pat her head but decided not to do anything in the end, so he just stood still. "Another shitty nightmare?" he said and saw her flinch, her arms tightened around him. He gruffed as his heart pounded silently. He thought of how he should still be angry with her when he was trying to wake her up but without any warning she had punched him but her actions dissolved the anger. "I'm guessing you fell asleep after you finished showering," he replied to her earlier question, A few minutes passed without any word from both of them.

Mikasa slowly let go of Levi and stood up from her bed. "I'm sorry," she said in a hoarse voice making Levi think that she had been crying the whole night instead of just moments ago, "I'll get ready to go to Erwin." She quietly went to the bathroom and slammed the door shut. "Damn brat," muttered Levi, "two years already and still you can't say a thank you at least." He touched the bruise on his cheek when the sting of it came back again. "Who were you fighting so desperately?" he wondered seeing as this was the first time she woke up from a nightmare with tears.
