It was comfortable.

The warmth of the blankets enveloping you, the soft and steady noise of the rain pouring constantly outside calming you somehow, the steaming cup of hot cocoa in your hands warming your permanently cold hands. Truly an ideal Sunday to spend inside lying on the couch all day long…

If you weren’t hangover.

Damn Eren for daring me to challenge Mikasa’s cousin in a drinking contest and damn that shrimp for having an iron liver. For being a meter and a kinder tall, that guy sure can drink.

Massaging your temple with your left hand, you could only regret your choices during the previous Saturday night and thank the gods your parents left early in the morning for their usual anniversary trip without waking you up to bid you goodbye. You would have never heard the end of it were they find out you got wasted with alcohol. You were the older sister in this house and you were supposed to settle a good example for you little brother, cute adorable smart Armin. Funny how your parents, after ten years, still thought you were the responsible one of the two. If it wasn’t for Armin to stop you the previous night, you would have gotten home more drank than you actually did.

Placing the now empty mug on the coffee table in front of the couch, you got into a more comfortable position and closed your eyes to get some sleep in hope this would wash away the throbbing in your head. Feint sounds coming from the kitchen reached your ears before you dozed off wrapped in the blankets like newborn.

 

Thump.

Your eyes snapped open and you fought with the duvet for a moment before realizing you went to sleep on the living room’s couch, with a massive headache and now you were lying on the floor after you rolled off the couch in your sleep. So much for a sweet wake up.

“____! Are you ok?” Armin’s worried voice made you rise your head from the floor and look at his preoccupied expression thought the curtain of your messed up hair.

“Fell from the couch.”

“Here. Let me help you.” With a sweet smile on his face, he helped you up the floor and out of the tangled blanket, making you sit on the couch again and smoothing your hair in place. “How are you feeling?”

“Better.” You replied in a sleepy voice. “Though my left arm is numb. Must have slept on it.”

“Think you can eat something? I made lunch.”

“If it’s your cooking, I’m definitely in!” You beamed happily; sleep quickly fading away at the thought of savoring Armin’s excellent cooking. The boy seemed to be good at everything as long as it didn’t involve tough physical labor. For being three years younger than you he was smarter, better in math, history and literature, could cook and was even cuter than you. People somehow always thought you would be envious and jealous of your little stepbrother for being younger and apparently better than you are at everything, but you couldn’t care less about such petite things. On the contrary actually, you were proud of having such an amazing brother.

Savoring the deliciousness of the beefsteak Armin cooked, you couldn’t be more happy. Food was always the way to bring you back to life and Armin knew well how to spoil you rotten. And without your parents around, he would spoil you to the core.

“So what are we doing today?” You asked between big bites from your meat, tapping with some salad at the end. Just then Armin hesitated with his answer. He stared at his plate intensely for some minutes, worrying you. Did he had plans for today? That didn’t involve you…

Don’t tell me he has a date with that blondie from yesterday… She was a little too close to him… Wait. This is where I should be happy for my little bro finally getting a girlfriend.

“…I’m sorry.” He said rather quietly.

It’s a date.

“I have an assignment to do due tomorrow, so I can’t spend much time with you, sis.” He looked at you from behind his bangs, remorseful.

Oh.

“No problem! Actually, I could help you!” You proclaimed cheerfully.

Thanks God it’s not a date. You mentally sighed in relief. Wait. Why am I happy it’s not a date?

“An assignment for physics.”

“…Oh.” You completely sucked at physics. Not as bad as math, but you were a disaster nonetheless.

“I promise it won’t take that long. We can still have a movie marathon in the evening. And I’ll make you carbonara for dinner.” The way he tried to justify the fact he couldn’t play with you because he had school to worry about made you feel guilty. You didn’t act like it at all, but you still were the older sister here. Why was your little brother the one responsible here? How could you make him worry for not being able to entertain you childish self? It was ridiculous.

“It’s fine, it’s fine. Take your time. I can entertain myself somehow.” You waved your hand at him dismissively.

“Yeah, you could read a book.” He suggested in a teasing tone accompanied by a small smirk. Armin was always your cute adorable little brother, but lately he became also quite handsome. His blonde locks brushing his shoulders and the bangs he let grow out this year gave him a rather cool appearance.

“Or play a videogame.” You grinned taking the last bite from your plate and making him look at your finished lunch. Armin was always a slow eater, while you devoured your food like a famished hyena every time. This was one of the many differences you two had. The list was quite long actually, making you almost polar opposites. Even so, you got along really well and you always thought it was because your brother put up with you a lot. You weren’t making many efforts on your side. He was just to kind and precious not to like him.

 

The afternoon wasn’t as fun as you had hoped. Laying upside down on the couch while playing Dark Souls was an activity of which you grew bored off rather quickly. Movies weren’t as interesting if you were watching them alone and it’s only been three hours since Armin excused himself to go study in his room. Groaning loudly, you placed your gamepad on the floor as a horde of spiders just killed you, for the third time. You reached for your phone and unlocked the screen glancing at the picture of you and Armin as kids you had as a wallpaper. It made you think of the first time the two of you met.

 

   There was a small cute blonde boy standing in front of you and clinging to his mother’s skirt half hiding himself behind her leg. He timidly shifted his bright blue eyes from between you and the floor as your parents introduced the two of you. If your dad had told you sooner his new girlfriend had such a cute son and that he would become your little brother, you wouldn’t have opposed so much to his remarriage.

   “Armin, say hi.” The lady urged him.

   “H-Hi.” Was his soft reply.

   “Hi!” He flinched at your cherry tone as you took a step forward and got a hold of his hands. “My name is ____ and I’m going to be your older sister from today on. You have beautiful eyes.” You smiled at him widely. “I’m going to take care of you, ok?” It didn’t really occur to you at that time that you were sort of forcing him to accept you.

   “O-Ok.” He blushed a bit and looked down at his feet, introducing himself shyly. “My name is Armin.” You didn’t waste time to pull your new family member in a tight hug.

 

You had about fifty unread messages.

“What the hell?” You actually did expect all of them to be from Hanji. What was surprising was the insane amount of photos she send you, all of them from the party of the night before. Scrolling through them, you saw a few containing events of which you had no memory of. “So this is what happened after we left.” You snickered at a picture of Jean and Mikasa’s cousin arm-wrestling, with Jean clearly struggling to win. A few pictures of you embarrassing yourself with the art of dancing and a video of Eren stripping to his boxers while yelling a German song.

“Damn, the kid actually has a nice butt.” You tried to contain your laughter while watching Eren twerk, while Mikasa was face palming in the background and Jean was literally rolling on the floor laughing.

“What are you looking at?” Armin’s voice came from above you and you shifted your eyes from the screen to him.

“Eren’s butt.” You laughed, passing him the device. The blonde watched with an expression between horrified and resigned. “Are you done with your assignment?” You glanced at the clock on the wall; it was still early.

“Yep. Worked fast so you wouldn’t have to wait for too long.” He handed the phone back to you, and you left your own comment under the video after you scrolled through Hanji’s texts.

“I said you could take your time.” You muttered, feeling happy nonetheless for his kindness.

“I know. But it’s rare we get to spent some time together since you moved in the dorms. I miss it.” He sat next to you and you shifted in a normal sitting position.

“Hot chocolate and zombie movies?”

“Does it have to be zombie movies?”

“Yep.”

Armin sighed and stood up. “I’ll go get the chocolate.”

 

You truly loved watching movies with Armin, especially scary ones. He would flinch quietly every time a horror scene would pass on the screen and then slowly inch closer to you for support. As the movie was ending, he had his arms wrapped around you as he tried not to look away from the disgusting creature feeding on a poor victim’s brain. You didn’t mind, not one bit, as you leaned against his chest. It was amazing how the once cute boy was growing taller and bigger with every passing week. Coming back home only for the free weekends you had from time to time really made you miss him. You didn’t even want to think how rarely you were going to see him in a year, when he would be going to college as well.

It would be even worse if he got a girlfriend. Now that would suck- Wait… Aarrgg! Don’t think about it ____!

Horror movies really had no effect on you. Some were so boring they made you fall asleep. Like this one. It was only after the movie had finally ended that Armin noticed you napping in his arms.

“____?” He checked for an answer, but the only thing that came from you was a soft sleepy moan. Armin smiled tenderly and placed a kiss on the top of your head before he turned the TV off and stood up from the couch with you in his arms. He wasn’t exceptionally strong, but he was at least able to lift you, albeit struggling a bit, and carry you to your room. He especially worked out for this purpose, seeing as you falling asleep on the couch during movies wasn’t a rare occurrence.

He gently placed you on your old bed and pulled the blanket over you, brushing some locks of (h/c) hair from your face and leaning closer to your face. He came to an abrupt stop an inch away from your parted lips blowing warm air against his. He blinked a few times while holding his breath. His lips pressed lightly on your cheek and he straightened himself deciding it was better to start preparing dinner.

What was I about to do?

 

You and painful awakenings were best buddies and it was a constant daily reminder. You have lost count already of how many times you woke up after you kneeled the wall beside your bed or fell off the bed. There were faint traces of your blows at the light green paint of your room and purple bruises on your knees almost constantly. The annoying pain was however forgotten quickly as you caught trace of a delicious aroma coming from the slightly open door of your room.

It took you about ten seconds to fly downstairs ready to satisfy your pleading stomach. The smell of pasta, bacon, eggs and cheese filled your nostrils completely as you stepped in the kitchen. Armin was giving you his back as he placed the cooked food on the table. His hair was tied in a small half bun with a few golden locks escaping the black hair elastic and he was wearing an apron.

“Finally up?” He asked turning his head towards you.

“Yeah. Did you carry me to bed?” You arched a brow at him, as you got closer.

“Yep. Didn’t want you to fall from the couch again.”

“Hmm. I see you got some more muscles here.” You snickered fondling his right arm.

“Y-Yeah.” He stuttered looking away from you, a small blush on his cheeks.

“What are you blushing for? It’s a good thing.” You slapped his arm playfully. “Though I kind of miss my cute little brother. Now you’re even taller than me. Are you going to stop growing at some point?”

“In a few years maybe.”

Setting up the table, you sat in your chair and waited for him to sit too before you started eating. You hummed in contempt when the first bite slipped down your throat and it didn’t take you long to finish your serving, asking for seconds. Armin got up and refilled your plate, as he was halfway with his.

“How can you eat so much and so fast? Aren’t you worried you’ll get fat? You remember me of Sasha.”

“Not my fault your cooking is so good. At the dorms, I usually eat half of what I eat at home. Between you and mom I can barely control myself.”

A sigh left his lips, as his eyes grew worried. “Are you sure you’re going to be fine? By yourself?”

You raised your brows curiously and blinked. “Oh, so dad told you.”

“Yeah. Why didn’t you tell me you’re getting an apartment and moving from the dorms?”

You rubbed the back of your neck nervously and avoided his questioning gaze, searching for the right words before you face your plate again. “I was going to tell you, but I wanted to find the right place first. I’ve been looking at a few, but I haven’t decided yet.”

“How come you decided to move?”

You sighed in defeat. At this point, there was no use to keep the secret any longer. “Well, I was going to get an apartment next year anyways, and since you’ll be attending college form next year too… and mom was worried about you going to dorms… I might have suggested I could get an apartment earlier and you could come live with me…?” Your voice become smaller and smaller with every word. “That, of course, if you want to.” You added hurriedly.

He took a moment to answer, staring at you as if you were some sort of alien creature and spoke in an unknown language. You sighed lightly, getting ready for a scene.

“Are you sure?”

“Eh?” Your head snapped towards him and observed his nervous expression.

“Are you sure you want me to come live with you? I mean, I’ll probably have to stay there for at least a couple of years before I can get an apartment of my own and-”

“It’s fine. I wouldn’t have suggested the idea if I wasn’t fine with it.”

“Ok then.”

“You mean you accept?” You asked and he confirmed with a nod. A wide bright smile broke on your lips as you shot up from your seat and walked next to Armin’s chair to pull him in a bone-crushing hug. “I’m so happy you are ok with it! I can’t wait to get the place. We should look at some together.”

He hugged you back and chuckled, standing up and lifting you from the floor. You yelped in surprise and looked down at him noticing the wide grin on his lips.

“Then let’s go next weekend and see some.”

You nodded in agreement. “Oh, but you can’t bring girls home.” You said in a more serious tone.

“As long as you don’t bring men I’m fine with it.” He shrugged and put you down, still resting his hands on your waist.

“Deal.” You grinned.

“Good.” He smiled back and placed a kiss on your forehead, causing a small blush to dust you cheeks. His action made him blush too and a slightly awkward silence settled. Inhaling sharply through your nose, you tiptoed slightly and kissed his cheek, quickly turning around to grab the dishes to wash, giving him your back to hide your red face. Armin’s ears and cheeks burned with crimson as he watched you grab an apron and get ready to do the dishes. A thought lingering in both your heads.

I’m happy we get to live together, but this will be complicated.
