Christmas shopping was way more stressful than people made it out to be.
In movies, Christmas shopping looked like what (y/n) would best describe as magical mayhem. Fairy lights twinkling in the trees as people mooched around with a cup of hot chocolate in hand. Excitement fizzling in the air as giddy patrons scrambled through the streets on last-minute missions to find the perfect gift for their loved ones.
Sometimes, though, Christmas shopping looked more like sitting on your sofa at 10pm, hunched over your phone, squinting at a Vinted listing and praying someone accepted your £40-to-£15 price drop offer so you could call it a day and feel a little better about yourself.
“Why is this so hard,” (y/n) sobbed as yet another seller declined her completely reasonable price offer.
Surely, it should have been illegal to charge more than twenty quid for a second-hand jumper. They were in a cost-of-living crisis for God's sake, not a bloody auction house.
When did people get so stingy?
Atsumu’s voice cut through the quiet, startling her into fumbling her phone. It bounced off her lap, then her knee, then made a sad little descent as it somehow managed to slip through the cushions, before clattering lifelessly on the wooden floor.
"Holding your phone, apparently,” Atsumu winced.
She was already dangling off the sofa to retrieve it, when a pair of socked feet appeared in her peripheral vision.
She glared up at him, unimpressed. Then, he nudged the phone toward her with his foot in a helpful, if not slightly condescending way.
She snatched it up with a muttered thanks, then righted herself just as the sofa dipped under his weight.
“I’m trying to look for presents,” she sighed, as she half-heartedly reopened the Vinted app.
Your offer for £20 has been declined.
“Eh, ya got plenty’a time,” Atsumu shrugged. “Christmas ain’t for another three weeks.”
“Still!” she cried. “I wanna get it done early for my own peace of mind. And the Black Friday deals are still on, so I wanna make the most of them. Thing is—guys are so hard to shop for!”
Atsumu snorted. “Too right. I ain't got a clue what to get ’Samu—let alone Suna. What doesn't that guy have, anyway?”
He had a point. Suna wasn’t exactly shy with his money. He'd buy whatever he wanted the second he wanted it, no questions asked. Meanwhile, she’d stare at her Amazon shopping cart for a week, mentally gaslighting herself that she didn’t need the thing even though she absolutely, undeniably wanted it. But that wasn’t the point.
“I was thinking of getting ’Samu another knitted jumper,” she mused, thumb tapping at her phone screen. “You know—since someone accidentally shrunk his favourite one in the dryer?”
Atsumu promptly avoided her gaze. “Wonder who did that.”
“You,” she deadpanned, prodding him in the chest. “Moron. You put it in the dryer when you were supposed to let it air dry.”
“It was an ugly jumper anyway,” he frowned. “I was basically doin’ him a favour.”
“That’s not the point,” she chided. “In fact, you should be the one to replace it since it was your fault.”
He made a noise that was somewhere between a grunt and a sigh, like the burden of his crimes was simply too great to bear. “I’ll think about it.”
Then, he perked up. “More importantly—what were you gettin’ me?”
He was facing her more fully now, his eyes practically gleaming. “’Cause if ya got no ideas, I could come up with a few. And best of all? None came with a price tag.”
She rolled her eyes. “Yeah, not a monetary one, I’m sure. No doubt I’ll be paying in other ways.”
"Why? Where's yer mind goin'?" he asked cheekily, eyes crinkling at the corners.
She gave him the flattest look she could manage. “Don’t start."
He leaned back into the sofa with an exaggerated sigh, lazily stretching his arm along the backrest behind her.
The fact he didn’t speak afterwards made her grow suspicious.
“You've gone quiet,” she murmured, squinting at him. “That usually means you’re up to something.”
“Hm?” He turned to her and blinked. “‘M just relaxin’. Enjoyin’ the festive atmosphere.”
“There is no festive atmosphere,” she countered. “We haven’t even put the decorations up yet.”
At that, Atsumu sprung to life, shifting in his seat so he could face her properly. It was as if he’d been waiting for this exact moment all evening.
Why, though, was what worried her.
"I'm glad ya bring that up, actually,” he said, sounding far too eager for her liking. “‘Cause I've got a lil somethin' here to brighten the mood. Lemme just—”
Before she could ask what on earth that meant, he held a hand up—and, from heavens knew where—produced a tiny sprig of mistletoe, strung up with a pretty red ribbon.
"Ta-da," he sing-songed. "Merry Christmas, (y/n). Pucker up.”
She stared at it in disbelief.
“Where,” she said slowly, “did you even pull that from?”
“My pocket," he said, matter-of-factly.
A laugh slipped past her lips. "It not even Christmas yet."
“Then call it practice for when the day comes,” he grinned, wiggling it over both their heads.
"Then I hope you believe in Christmas miracles," (y/n) retorted as she pushed herself from the sofa. "'Cause that ain’t happening."
“Scrooge," Atsumu called behind her.
She snickered, grabbing her half-empty mug off the coffee table and heading toward the kitchen.
A hot chocolate refill sounded divine right about now. However, she paused at the doorway when curiosity got the better of her, then glanced over her shoulder.
Atsumu was slumped back on the couch, his hoodie thrown over his head, the collar pulled over half his face. Despite the messy fringe poking out, she could still make out his little frown, and the tiny sprig of mistletoe, now abandoned in the palm of his hand.
The next morning, (y/n) stepped into what felt like an entirely different apartment.
The decorations had gone up overnight. Fairy lights now twinkled across the ceiling beams, casting a dreamy, golden glow across the living room. Tinsel wrapped around every doorway, like the entrance of Santa's grotto itself. But the best feature had to be the Christmas tree that despite its size, stood proudly in the corner next to the TV, decked out with mismatched ornaments and a lopsided star.
It was beautiful. Better than last year’s, even. She glanced around and hummed, surprised at how everything had been done neatly. Meticulous and thought out. Which was... shocking, given she lived in a household of guys.
She wandered into the kitchen, where the scent of cinnamon and vanilla greeted her like a warm hug.
Of course, she found Osamu already at the stove, flipping what looked like a fresh batch of blueberry pancakes—an upgraded recipe for the colder season apparently, judging by the dusting of something spiced.
“Morning! I like the decorations,” she greeted with a smile.
“Yeah?” He didn’t look up from the stove, but he sounded just as pleased. “Tsumu did ’em. Think he wanted to surprise ya.”
“He did?” (Y/n)’s smile deepened even further.
Usually, she enjoyed decorating together. Spending an afternoon tangled in fairy lights, listening to cheesy Christmas songs as hot chocolate brewed on the stove. But the thought of Atsumu staying up late, frustrated but still determined to figure out what tinsel goes where just to impress her, was just as sweet.
“Well, I’ll be sure to tell him he succeeded,” she murmured, drifting closer to Osamu’s side.
She peeked into the pan, watching bubbles rise through the thick batter. “Need a hand?”
“Sure,” he replied, flipping the pancake with a practiced flick of the wrist. “Mind grabbin’ the plates? ‘M almost done.”
She sang out a little “yessir” and reached for the cupboard above. As she stood on her toes, something that hadn't been there before caught her eye.
There, hanging neatly above the archway, was a familiar little plant. One with the same small leaves, tiny white berries, and cute red bow as yesterday.
"Is he serious?" she muttered, huffing out a half exasperated, half amused laugh.
“Hm?” Osamu glanced over.
She grabbed the plates, nodding toward the culprit.
He followed her line of sight, and blinked in surprise. “How’d that get there?”
“Your brother,” she sighed, closing the cupboard with a gentle click. “He tried to get me with one yesterday. Pulled it out of his pocket like some kinda touch-deprived magician."
Osamu let out a quiet snort as he began helping her with the table. The two of them moved easily around each other, falling into a rhythm they had grown to perfect over the years. She laid down the plates while he reached into a drawer and passed her the cutlery.
Soon enough, a high stack of pancakes sat in the centre of the table, still steaming and lightly dusted with icing sugar.
“And?” he asked, that familiar teasing lilt sneaking into his tone.
She lifted an eyebrow. “And I left him hanging, of course.”
He chuckled and shook his head. “Yer brutal.”
(Y/n) shrugged. Turning down Atsumu’s advances was nothing out of the usual. Besides, she was more preoccupied with the absolute feast Osamu had prepared for them to think about that right now.
Not only were there pancakes, but the moment he brought out a bowl of honey-glazed berries, it was over for her. Her stomach grumbled impatiently, while her mouth practically watered at the promise of eating herself into a festive coma.
She barely registered Osamu’s voice, only to be pulled out of her thoughts when he gently elbowed her side.
Well, that was never a good sign.
She obeyed anyway, tipping her chin toward the ceiling.
There, hanging right above the table, strung up with neat little twine was another sprig of mistletoe.
“You have got to be kidding me,” she gawked. “How many has he put up?!”
Osamu shook his head, arms on his hips as he looked up at it.
“I can see this one bein’ a pain,” he muttered, reaching up to untie the sprig. “No smoochin’ at the dinner table.”
She was watching as his fingers deftly worked at the knot when a silly thought passed through her mind.
Was she meant to kiss him?
Not kiss-kiss him, obviously. This was Osamu. Practically family. Most likely, the thought hadn't even occurred to him.
They were already standing under the dumb thing. And, well—it was tradition, she supposed.
Rising up on her toes, she leaned in and pressed a quick kiss to his cheek, grabbing the mistletoe from his hand in the same breath.
“For breakfast,” she said casually. "And every breakfast before that," she added quickly.
Osamu blinked, pausing mid-motion. He looked genuinely surprised. But that surprise quickly softened into something more amused.
“Aw, thank you, darlin’," he cooed. "You know I enjoy cookin' for y'all."
"And we enjoy eating your cooking," (y/n) enthused, twirling the mistletoe between her fingers. She caught Osamu’s smile as she placed it on the windowsill—out of sight and well out of kissing range.
She jumped at the sound of Atsumu’s voice.
He walked into the kitchen with the gait of someone who had slept for days. One hand shoved up his shirt, yawning loud enough to wake the dead.
“Morning,” (y/n) and Osamu called in unison.
He stretched and gave a grunt as his joints audibly popped. The second his eyes landed on (y/n), a wide, sleepy grin spread across his face.
“Yeah! I love them,” she beamed, before adding: “Well—most of ‘em.”
Osamu shot her a smirk, which made Atsumu’s brows pinch in suspicion.
“Most of ’em?” he repeated. “Why? Which ones don’t ya like?”
(Y/n) glanced up at the ceiling, then toward the windowsill. Atsumu followed her gaze—only for his mouth to drop open. He stared at her like she’d just maliciously kicked over a nativity scene.
"What—Why'd ya take it down!""
"Because 'Samu and I stepped under it,” (y/n) snorted. “Twice."
She bit her lip to smother her grin.
Atsumu's face instantly fell, contorting in horror as he looked between (y/n) and his brother.
“Relax, nothin' happened," Osamu said dryly, clapping a hand on his twin's shoulder. “But I took it down in case ya ended up under there with Suna, or somethin’.”
“Or you,” (y/n) added, nodding at Osamu—who immediately grimaced at the mental image, just as Atsumu pretended to throw up into his own mouth. Charming.
"Yer makin' me lose my appetite," Atsumu shuddered as he pulled out a chair.
"More food for me," she chirped, settling beside him.
And to think, if Osamu hadn't cut down the sprig, it would be her and Atsumu caught beneath the mistletoe right now.
But as her gaze flicked toward the windowsill—toward the abandoned sprig of mistletoe now lying harmlessly in the soft morning light—she found herself wondering if she'd have even minded at all.
By mid-afternoon, everyone had settled into their own little routine.
(Y/n) padded into the living room, nursing her third hot chocolate of the day and half a mind to start one of those B-list, overly saturated Christmas movies.
She found Suna exactly where she expected him: curled up in the sofa like a particularly grumpy house cat. Hood up, bored expression, legs propped up on the coffee table.
He looked like he hadn’t moved in an hour. How he hadn’t already moulded and become one with the cushions was a Christmas miracle in itself.
He was slurping on one of those jelly stick things—those lurid, sugar-loaded tubes he’d been obsessed with since he was a kid. His thumb flicked through his phone while the snack hung out of his mouth like a bright purple cigarette. Grape. His favourite.
“Do you ever eat anything solid?” (y/n) asked, flopping into the spot beside him whilst eyeing the two energy drinks on the table.
“Shock,” she deadpanned. Then reached for the TV remote. “I’m putting a movie on. You can veto once and only once.”
“Anything but Love Actually,” he muttered.
Rude. (Y/n) actually enjoyed that film.
In the end, she settled for good old Home Alone—a classic for the holiday season. But just as she was about to hit play, she noticed something.
Dangling from the lampshade right above their heads.
This was getting ridiculous.
Her lips parted in genuine disbelief. Suna, following her gaze, took the jelly stick out of his mouth and raised a brow.
“I honestly think Atsumu's lost the plot,” she said, staring at the blasted plant. “He's relentless."
“Honestly, I respect the commitment.”
She grimaced and turned to Suna. Before she could say anything else, he cut in.
She wasn't sure what offended her more. The fact he assumed she wanted to kiss him in the first place, or the fact he shut down the idea so quickly.
Actually, it was definitely the second reason.
"You said that a little too fast for my liking."
Suna quirked a brow. "Why? Did you want me to kiss you?"
"No,” she scoffed. “I said it was the speed at which you denied it. The speed.”
He hummed and gave her a look that was difficult to place. “You sure? ‘Cause it sounded a lot like you were angling for it.”
(Y/n) lifted her chin. “Gross,” she sneered, all in good fun. If anything, she just wanted to back at him for the no kissing comment. And maybe because he’d caught her a little off guard, too.
“Still, you didn’t have to be so rude about it,” she pouted. “You act like you haven’t kissed me before.”
She’d expected him to completely brush off that comment. To remain perfectly unfazed like he always was. So when it actually made him falter—just a subtle shift in posture, like a cat flicking its tail—she felt just a little bit smug.
“We were eighteen,” he droned. “And you were very much into me."
Her lips pulled into a thin line.
What a classic Suna response at that—straight for the jugular. Never one to cut corners when he could emotionally snipe the person instead.
Still, (y/n) years of knowing him made her bounce back quickly, brows lifting in mock indignation.
“Uh—first of all, you made the first move. I just went along with it.”
That was a big fat lie. She had been obsessed with him at the time. “Going along with it” was a very mild way of retelling history.
“I said you could tell me to stop," he said, lip twitching because—touché—they both knew she hadn’t.
“Who’s the gross one now?”
“Still you," she shot back, then slumped deeper into the cushions. “You know, for someone who loves teasing me about this, you sure have a selective memory—"
She never got to finish her sentence.
One minute she was mid-tangent, growing progressively more riled up as Suna rose his brows at her in challenge. Next thing she saw was his eyes narrowing, the twitch at the corner of his mouth as he leaned in—before he shoved the jelly stick into her mouth.
“There,” he said calmly. “That’s your kiss.”
She flinched, speechless, as the sickly-sweet artificial grape flavour coated her tongue.
“I didn’t actually want—“ she cut herself off and forced herself to chew. A bit of the juice trickled down her chin. “And how is that—?”
“An indirect kiss,” he smirked, then used his thumb to swipe the corner of her mouth. “That way I don’t get your weird mouth germs.”
She whacked him with the back of her hand, then wiped the bottom half of her face herself.
He curled up on instinct, laughing into his hoodie as she whacked him again for good measure.
“Prick,” she muttered, crossing her arms over her chest.
He peeked out from under his hood, all mussed hair and lazy eyes, his voice growing a touch softer.
“I didn’t upset you, did I?”
She shook her head and flashed him a smile. “No. It’s fine,” she huffed fondly. “You’re just annoying.”
“Good,” he said. Then, bumped his thigh against hers.
She bumped it back for good measure, just a touch harder.
By evening, (y/n) had seen enough mistletoe for a whole lifetime.
How Atsumu had managed to decorate and hang up so many in one night was beyond her. Maybe it was those deft setter hands of his.
Or maybe he was just desperate.
Actually—yeah. That seemed more likely.
She’d found them everywhere. Above the dining table, the couch, in the hallway, in every doorway. There wasn’t a space in the apartment where she didn’t risk an unsolicited smooch.
Well—save for her bedroom. And perhaps the balcony.
Which, thankfully, was where she was headed now to unwind.
Not that the day had been stressful, by any means. Even if she spent a tedious amount of time removing those pesky little sprigs around the house.
It simply felt nice stepping outside every once in a while, watching the world below go by. It was peaceful. Quiet. All things she craved after being cooped up all day.
As she slid open the door, the cold greeted her immediately. She clutched her blanket closer, her breath curling in front of her before dissipating into the icy air.
"It's freezing," she muttered.
She was about to sit on one of the garden chairs they kept out there for evenings like this, when something all too familiar caught her eye. This time, dangling from the fairy lights overhead.
At this point, it was less disbelief and more sheer defeat.
"I can't believe him," she sighed, stepping forward to inspect the latest, tactfully placed sprig.
She shook her head and rose to her tiptoes to untie it—cold fingers fumbling with the ribbon. In the same moment, the door slid open behind her.
"Yer persistent, ain't ya?"
She glanced over her shoulder to find Atsumu stepping onto the balcony, a lazy half-smirk plastered on his face.
“You can talk,” she scoffed, still working at the knot. The cold was making the task significantly more difficult, her fingers numb and half as nimble.
He must’ve noticed, because a moment later, he was beside her. “I got it,” he said, gently nudging her hands away. “As much as I wish ya’d keep ’em up.”
She let him take over. From where he was standing, she could feel the warmth radiating off of him. If she leaned back just an inch, her blanket-covered back would hit his chest.
Not that she was thinking about that.
It was just cold outside. And Atsumu was practically a human furnace, so...
If anything, it was more of a reflex. A survival instinct against harsh weather conditions.
"Why’d ya insist on takin’ them down?" he asked, fiddling with the ribbon.
"'Cause they’re inconvenient,” she muttered. “And I'm pretty sure nobody actually follows that tradition anymore, so… no point keeping them up.”
She realised the hypocrisy of her words as she thought back to her encounters with Osamu and Suna.
“Plus they'll wilt,” she added.
"Mistletoe keeps for weeks," he argued. "And anyway, it was meant to be a joke. I knew y'all would ignore it." He shot her a sideways glance. "Especially you."
The words what's that supposed to mean? were right on the tip of her tongue when Atsumu plucked a tiny white berry from the sprig, rolled it between his thumb and forefinger and said:
"You're berry prudish these days."
He finished his sentence by flicking said berry at her, pinging her square on the forehead.
"I am not prudish," she huffed.
Atsumu chuckled, which only made her more defiant. “If anything,” she said, “you shouldn’t need a plant as an excuse to kiss me anyway.”
She clocked her mistake the moment Atsumu went quiet.
He blinked, clearly processing the implications behind her words, before a sly grin crept onto his face.
"I beg yer pardon?" he teased, all mirth.
Her eyes widened. “No—I didn’t mean—”
Damnit. How was she going to worm her way out of this one?
"I meant, if ever you were going—or wanted to kiss me, or something—then you should at least make it more authentic, you know?"
"Again, I'm not saying you should, or that I want you to," she rushed on. "I just mean if ever you did. Like—hypothetically speaking, then..."
She clamped her mouth shut before she could dig her grave any deeper.
There was absolutely no reason for her to have said that much. Now, Atsumu definitely thought she wanted him to kiss her.
Nor did she want him to kiss her this very second, for that matter.
He was standing pretty close already. Hardly an arm’s length away. Plus, it was cold. And there was no doubt she’d feel warmer with Atsumu’s hands running up and down her back—
She banished the thought.
She expected teasing on his behalf. A sly comment. Perhaps even for him to outright turn her down.
Atsumu was rooted in place, flushed, his lips parted like he wanted to say something, but couldn't quite find the words.
Somehow, that was even worse.
His lips parted, then closed again. The tips of his ears reddened as the silence stretched on.
(Y/n) wasn’t faring much better.
Either the temperature had suddenly spiked or her blanket had a heating feature she didn’t know about, because her face felt unbearably warm.
“This is silly," she blurted eventually, forcing the words past her throat. "It’s just a plant. You don’t actually have to—“
“No, I know,” Atsumu cut in, lifting both hands in surrender. “It’s just…”
Had she come across as too eager?
Had she made him uncomfortable?
Pressured him, somehow, by assuming he might actually want to kiss her?
She didn't push, giving him the chance to find his own words.
And to her surprise, Atsumu didn’t look uncomfortable. Or pressured. If anything, beneath all his usual bravado, he looked… kind of bashful?
“Yer right,” he said quietly. He turned the mistletoe over in his fingers a few times, watching the movement pensively—then lobbed it into the skyline.
“I shouldn’t need an excuse.”
For a moment, his hand just hovered in the air, like it wasn’t quite sure what to do now that it was no longer holding anything. It dropped to his side, rose again, then scratched the back of his neck.
She watched him, even as he struggled to meet her gaze. He had the face of someone trying to think his way out of a feeling—the furrow in his brows, the crooked, un-Atsumu-like grin he flashed her a second later.
“It’s okay, ‘Tsum,” she said gently. “There’s no rush.”
Because as flighty as Atsumu was when it came to… well, them—she understood.
She understood that his hesitation wasn’t because he didn’t care. If anything, it was because he cared too much. Because he was scared—of the timing, of the weight of it all. Of choosing her only to fall short later. Of committing to a relationship he wasn’t sure he could properly nurture just yet.
And sure, he was frustrating sometimes. Prone to retreating behind jokes or letting silence do the talking when, really, she just wished he'd speak his mind.
But she’d seen the other side too. The man who always lit up when she entered the room, who was constantly trying to overcome his flaws—for both their sakes.
He didn’t always know how to show it. But deep down she knew that he felt it. Because that was the thing about Atsumu: he felt with his whole heart. Even when he didn’t necessarily have the words for it.
At her reassurance, he finally glanced over. A little surprised, maybe. His eyes roved her face, as though searching for any trace of doubt. But when (y/n) only stared back, her expression open, he nodded, plain and simple.
A moment passed between them. They turned toward the balcony, gazing at the twinkling city lights below. And, just to ease what little of the tension remained, (y/n) elbowed his side.
“Don’t worry," she assured, "I know you can be berry cautious about these things.”
Atsumu’s laughter felt like instant gratification. An honest, crinkly-eyed laugh that made her stomach do a little somersault.
“Very funny,” he muttered, shaking his head.
He side-eyed her. “‘Kay, now yer overdoin’ it.”
“Says you,” she shot back. “You mistletoe fiend. I’m surprised you didn’t hang any over my bed.”
“I’m only jokin’,” he grinned. No masks. Just pure, unfiltered affection. “No excuses, remember?”
Warmth bloomed in her chest.
She shifted so that she could see him better. He mirrored her. And for a moment, she simply… looked at him. He was the same old Atsumu, albeit a bit windswept. Handsome—more so, now that there was nothing performative about him.
His eyes softened, and she didn't miss the way they dropped—just a fraction—to her lips.
She parted them, and that was when he seemed to catch himself, flicking his gaze back up, a little too fast. Like he hadn’t meant to look. Like he’d surprised himself.
Then, without a word, he pulled her in. His arm wrapped around her back as he rested his chin atop her head, conveniently hiding whatever expression lingered on his face.
(Y/n) laughed softly and hugged him back.
“I saw that,” she whispered, just as a breeze swept past them.
It must have stolen her words along with it, because Atsumu didn't respond. He just hugged her tighter.
Somehow, (y/n) liked this more than any kiss.
thank you to everyone who likes, comments &/or reblogs! ☺️
