Happy reading!

I made blueprints for a treehouse

Towering high over the summer in July

And my backyard held a meadow

And we two were the only ones who knew

Levi woke up the next morning feeling much better, turning off his alarm and blinking the sleep from his eyes. Once he felt a bit more awake, he turned his head toward the window, not at all surprised to see a very thick blanket of snow covering the campus. He was equally unsurprised when he checked his phone and saw an email from the university stating that classes had been canceled for the day due to the snowfall.

What did surprise him, though, was looking down and seeing Aria tucked against his side, sleeping peacefully. While not an unwelcome surprise by any means, Levi had been tempted to write the previous evening off as a very pleasant fever dream.

'Gotta admit, this isn't a bad way to wake up,' he thought, reaching over to grab Aria's phone and turn off her alarms before settling down next to her again. He brushed a stray strand of hair from her face, smiling when she nuzzled her cheek into the palm of his hand.

He watched her sleep for a while longer until his stomach growled. Reluctantly, he climbed out of bed and headed into the kitchen, shuffling through the fridge as he tried to figure out what to make for breakfast. He knew Aria wasn't a terribly picky eater but he still wanted to thank her for taking care of him. After much deliberation, he decided on making ham and cheese omelets for the both of them.

Once breakfast was ready, Levi poked his head back into his bedroom. Aria was still fast asleep in the exact same position as when he'd left. He slowly made his way over to the bed and, remembering that she was ticklish on the back of her neck, brushed her hair away from her nape and wasted no time wiggling his fingers over her ticklish spot.

Aria's eyes immediately flew open and she squirmed away from him, giggling and bringing a hand up to cover her nape. She rolled over to look at Levi, smiling up at him, before looking out the window and blinking in realization.

"Levi, what time is it?" Aria asked.

"A little after nine," Levi answered simply. Seeing the panic in Aria's eyes, he added, "You're not late for anything, if that's what you're worried about. We got an email this morning that classes were canceled because of the snow, so I turned off your alarm."

"Aww, you're such a good wife, Levi," Aria joked, getting out of bed and stretching. "Hold on. If classes were canceled, why'd you wake me up?"

Levi shrugged. "Breakfast is ready. Figured you'd want to eat before it got cold."

"You made breakfast for me?" Aria asked, gathering up her phone and following Levi out into the kitchen.

"It's nothing too fancy, just a ham and cheese omelet," Levi replied, grabbing the plates and forks and handing one to Aria. He sat down on his couch and turned on the T.V., gesturing for Aria to join him.

"I didn't know you could cook," Aria said as she sat down with him, digging into her food.

"I don't really have much of a reason to, considering how inclusive our meal plans are, but I wanted to thank you for taking care of me yesterday."

Aria smiled after swallowing a bite. "Levi, this is incredible! Do the guys know you can cook like this?"

"No. I haven't really cooked for anyone besides Farlan and Isabel," Levi replied, starting on his food as well. Though he kept his expression neutral, he was happy that Aria enjoyed his cooking. 'I also don't normally cook for people unless they mean a lot to me, sweet stuff.'

The pair continued to watch television after they'd finished eating, Aria running her fingers through Levi's hair as she had the previous night. Levi was beginning to enjoy Aria's touch more and more and he found himself tilting his head toward her so she could reach more of his scalp. He began unwittingly entertaining thoughts of how her hands might feel on other parts of his body but he did nothing to stop them. This hadn't been the first time he'd had sexual thoughts regarding Aria and he'd learned that trying to repress them only made them worse, usually resulting in some rather erotic dreams.

When the thoughts first surfaced, Levi had been almost appalled, but eventually he came to realize that it was a natural part of being attracted to someone. Besides, he had a sneaking suspicion that Aria wasn't as innocent as she looked.

Aria's fingers suddenly ceased their ministrations to Levi's scalp and he looked over at her, disgruntled. "Why'd you stop?"

Aria looked up from her phone. "Text from Hanji. Everyone's meeting for lunch in about ten minutes. You wanna go?"

Levi nodded. "Yeah, we might as well. Your roommates might assume I'm holding you hostage here otherwise."

"That's the truth. I got about eight 'where are you' texts from Hanji last night," Aria laughed, removing her hand from Levi's head and standing up. "Before we go, though, I need to stop by my room and change. There's a lot more snow out there now than when I came over last night and these clothes and shoes aren't going to cut it."

We turned the hillside into a castle

And chased off dragons side by side

Over the picket fence lay an imaginary paradise in the sky

"Noticed you didn't come back last night, Aria," Hanji said when Aria sat down.

Aria quirked an eyebrow, understanding what her friend was hinting at. "Right. And I noticed you and Bri decorated the room for Christmas when I stopped in to change clothes. If we're done pointing out the obvious, I'm going to eat now."

Eld blinked. "Wow. You've been spending way too much with Levi; he's starting to rub off on you."

"In more ways than one, I'd imagine," Hanji added, wiggling her eyebrows suggestively as Aria's cheeks reddened.

"Leave her be, shithead," Levi said, sitting down next to Aria. "She stayed with me because I asked her to. Nothing happened, but I'll damned if I didn't get some amazing sleep last night. Drop it."

Hanji didn't comment any further on the previous evening, though she did make note of Levi's growing protectiveness over Aria. 'I ship it. I ship it so hard.'

Bri shook her head playfully before turning to Aria. "So, there's going to be another unofficial concert for spring semester around Valentine's Day. Are you going to sing for us again, Aria?"

"Hell yeah! I was wondering when you were going to ask!" Aria replied without any hesitation, much to Bri's surprise and delight.

As the group continued to converse about the next semester, Bri noticed that Aria kept glancing outside at the snow-covered campus with a small smile on her face.

'She really is like a little kid sometimes,' Bri thought before poking Aria on the shoulder. "Do you want to play in the snow?"

The smile that lit up Aria's face was all the answer she needed.

I fell in love with your starry eyes of deep blue skies

And when I hold you close, my dear, I feel like we could fly

I know your smile will be always in my heart

So close your eyes and dream of the skies

And I'll be here with you in our treehouse

The group had made their way to the snow-covered field behind Smith Hall. Aria had immediately begun playing in the snow once they got there, Hanji joining her just a moment later.

"So tell me again why snow's so important to her," Levi inquired to Bri as they watched Aria and Hanji play. Eld, Gunther, Oluo, and Petra had joined the girls in a sort of mini snowball fight.

"I wouldn't say it's 'important' to her so much as it reminds her of home. Winter's her favorite season and she's always been happier in colder weath-," Bri was promptly interrupted by a snowball to the face while Levi was hit in the side of the head.

"Come on! Quit standing over there like a couple of party-poopers!" Hanji shouted, Aria cracking up next to her.

"Alright. Come here, you little shit," Levi said, taking off after Aria as Bri proceeded to charge Hanji.

Soon enough, what had started as a snowball fight between friends had evolved into snowball war involving half the student body. There were no sides, snow was flying everywhere, and the only rule was hit or be hit.

"Aaargh, I've been slain!" Aria gasped out dramatically, clutching at her heart when a snowball struck her arm, before sinking to the ground.

"Come on, get up," Bri said after Aria had laid there for a minute or two, looking down at her with an unamused expression.

"I'm dead," Aria replied simply, not moving from her spot on the ground.

"Mmm, no you're not," Bri retorted.

"Fine," Aria sighed, pushing herself up and onto her feet. "Where's Eren? I'm pretty sure he's the one that hit me and it's time to pay him back."

"I don't think you have to worry about that," Bri smirked, nodding her head to Aria's right. "Levi's got it taken care of."

Aria looked over in the direction Bri had nodded to see Levi mercilessly pummeling Eren with snowballs. "That's what you get, Jaeger!" she shouted over to the boy.

"Whatever, Aria!" Eren yelled back. "You know I only threw that snowball at you out of love!"

It may have been her imagination, but Aria thought she noticed Levi pummel the poor freshman even harder after that comment was made.

We held picnics on the rooftops

And left our cares in the wintergreen air

We threw flowers and paper airplanes

Over our town and laughed as we looked down

Levi jerked forward as a snowball hit the back of his head, causing him to cease his assault on Eren. He whipped around, glaring, only to see Aria behind him, looking away innocently. She barely had any time to react before he had tackled her into the snow, pinning her body to the ground with his.

"That's twice today, Red," Levi smirked as Aria squirmed underneath him. "I think it's time for a little payback."

With that, he picked up a handful of snow and shoved it into her face. Aria squealed and laughed, glad Levi had decided to play along as well. She wiped the snow out of her face, her eyes widening when she realized just how close Levi's face was to hers; his lips were hovering just inches above hers. Levi appeared to be thinking along the same lines and, at this point, the coloring in their cheeks had nothing to do with the cold. The pair stared at each other, seemingly frozen in place, each contemplating closing the gap between their lips. Finally, Aria brought her face closer to Levi's and gently rubbed her nose against his in a sweet Eskimo kiss. Levi's cheeks flushed even darker, but he awkwardly returned the gesture as well before reluctantly climbing off of Aria and pulling her to her feet.

Petra had been watching the exchange from a short distance away, the same sad look in her eyes as before. She snapped out of her daze when someone tapped her shoulder.

"Everything okay?" Bri asked.

Petra forced a smile."Y-Yeah, everything's fine. Sorry, I just spaced out a little."

We turned the hillside into a castle

By the time the sun was starting to set, the snowball war had ended. The students, tired and soaked, but happy all the same, drug themselves back to their dorms or to get something to eat.

"Hey, Levi," Aria began as the two began their walk back to Recon Hall. "Would you... Would you maybe want to...I don't know...stay over with me?"

Levi blinked. "R-Really?"

Aria nodded, her cheeks flushing. "Yeah. I mean, Bri said she was staying over with Eld tonight anyway and... I could really use my favorite cuddle buddy."

Levi's cheeks flushed as well. "That...That sounds really nice, actually." He paused before looking over to her. "Wait, what do you mean 'favorite'? You have other cuddle buddies?"

"You're the only male one," Aria replied.

"Good," Levi nodded. "I'm going to stop back at my room first to take a shower and change, though."

"I was thinking the same thing," Aria agreed as they entered Recon Hall. "I want to take a hot shower and see if I can get some feeling back in my legs. Just text me when you're on your way."

"Will do," Levi said, heading in the direction of his room.

I fell in love with your starry eyes of deep blue skies

And when I hold you close, my dear, I feel like we could fly

I know your smile will be always in my heart

So close your eyes and dream of the skies

And I'll be here with you in our treehouse

Levi knocked on Aria's door a short while later, smiling when she opened it and handed him a mug of hot chocolate. He followed her into her bedroom, nearly dropping the mug when he noticed that she was wearing a pair of shorts as pajama bottoms. Up until this point, Aria had always worn jeans or sweats around him, so Levi had never seen her bare legs before. And he was not disappointed. Aria had mentioned that she had been dancing most of her life, so Levi wasn't terribly surprised that her legs were so toned. He could see the muscles working as she walked and, honestly, he thought it was one of the most beautiful things he'd ever seen.

Aria turned to him when she felt him staring at her. "Everything okay?"

Levi shook his head, snapping out of his stupor. "Yeah. It's just... I've never seen your legs before."

Aria looked down as if suddenly realizing what she was wearing. "I can put on sweats if it's bothering you."

"No, no, I didn't mean it like that," Levi said hurriedly. "They don't bother me at all; I actually think they're... I think they're beautiful."

'They're also the sexiest legs I've ever seen and I'd have no problem with you wrapping those beauties around me and never letting go,' Levi thought.

"Really? I've always the muscles made them look a little...off," Aria said.

Levi shook his head, both as a way to reassure her and to rid himself of his thoughts. Aria smiled and settled down on her bed. "I figured you'd rather just chill with me in here. I have no idea when Hanji's going to be back and I doubt either of us want her insinuating anything."

"You figured right," Levi replied, settling in next to Aria as she turned on her T.V.. "And since you're going without pants tonight...,"

'Holy shit,' was all Aria could think as Levi pulled off his shirt, revealing a very impressive set of abs.

"No. No way. No way in hell," Aria said, scooting closer to Levi and running her hands over his abdomen. "There's no way those are real."

Levi chuckled. "What, you think just because I'm an art major, I don't work out sometimes?"

"I just... I never would have guessed," Aria replied, still running her hands over his abs as her fantasies went into overdrive.

Unbeknownst to Levi, Aria had similar sexual thoughts towards him. And, much like Levi, she had learned that trying to push them away only resulted in erotic dreams later on. She was certain she'd be seeing his abs in a few of them now. 'Hopefully, it's the one where he gives me a lapdance,' she thought.

A few cups of ramen and some episodes of Whose Line Is It Anyway? later, Aria and Levi had snuggled under the covers, settling in for the night. Both had been fairly exhausted from the snowball war, and Aria had fallen asleep almost immediately. Levi couldn't help but grin as she curled into his side, wrapping her arms around his torso. He began gently petting her hair, looking down at her sleeping face. She always looked so peaceful when she slept and he couldn't stop himself from nuzzling his nose against hers, much like she had done earlier that afternoon.

He watched her for a while longer before his own eyelids grew heavy. He snuggled closer to Aria, wrapping his arms around her and smiling as she cuddled closer. His eyes were drawn to her lips, once again parted just slightly as she slept. He hesitated for a moment before leaning down and gently pressing his lips to hers. The kiss was brief and he reluctantly pulled back, chuckling as Aria smiled in her sleep, mumbling incoherently.

'Sweet dreams, Red,' Levi thought before closing his eyes and falling asleep as well.
