Word Count: 3 k

Author's Note: This one is defo shorter than usual, but I wanted to write one a bit more simple since... I feel like that last one did a number on my brain ngl😭.

Req: @1luvkarina (I DELETED THE REQ ON ACCIDENT SO BARE WITH ME FUC-) A Yooyeon fic, where the reader is SeoAh's older sister, and you're a KIOF member.

➳ Character Concept - Jeong Y/n

The waiting room at the KBS building was always a wild rollercoaster when Music Bank was being filmed. With tripleS, it was chaos, the twenty-four girls taking over several waiting rooms. Today was slightly less intense, as only twelve members were present for the debut of their new subunit, Visionary Vision.

Not that cutting the team in half did much to ease the madness. Girls were scattered everywhere, napping, getting their hair and makeup done, or diving into random activities. In one corner, however, one member sat quietly, completely focused.

The well-known “Ewha Goddess” was always diligent, balancing her idol life with personal indulgences. Even now, Yooyeon had her iPad and Apple Pencil in hand, creating neat, color-coded notes. She wasn’t in school anymore, but she studied whenever she had a spare moment, always preparing in case she decided to return to university.

The television at the room's far end played several performances from idols promoting their comebacks. Yooyeon hadn’t been paying attention—until Kiss of Life appeared on the screen.

Her gaze shifted at the sound of laughter, and there you were, standing with your members as Park Minju and Moon Sangmin interviewed the group.

“So, Y/n, is there any advice for anyone who wants to try dancing to your song?”

You nodded with an easy smile, stepping forward as the others cheered you on. Yooyeon watched as you clasped your hands together, a small but endearing habit she’d noticed since she started following your group.

“So when you lean forward, you always want to have a smug expression or your tongue out,” you demonstrated, sticking your tongue out playfully. “And you want to proceed to do this confidently,” you added with a grin.

The MCs laughed, signaling the music as you danced between them, showing off the signature moves from Igloo.

Yooyeon couldn’t take her eyes off you.

She barely stayed registered for the rest of the interview. Ninety percent of her focus was on you—the way you moved and spoke. You had a natural charm, but it wasn’t just that.

You had this quiet confidence, a poised and commanding presence that pulled people in without effort. You weren’t the eldest in your group, yet you carried yourself like someone who was.

Yooyeon admired that. The way you crossed your legs, sat up straight and managed to keep your members in check during shows left an impression.

Sometimes, she would scroll through social media, seeing clips of you feeding your members during meals, guiding them through chaotic moments, or effortlessly getting people, idols and strangers alike, to follow your lead during variety shows. She’d watch every video she found, her fascination growing each time.

The interview transitioned to the prerecorded stage for Igloo. Yooyeon relaxed in her chair, setting her iPad aside as the music began. The sensual, playful melody filled the room, but her attention stayed on you.

She couldn’t help it—everything about you was captivating. The way you leaned into each move with purpose, the playful glint in your eyes as you taunted the camera with your smug expression.

Yooyeon barely noticed her own members talking in the background. She was too focused on you, her mind racing with thoughts she couldn’t quite articulate but knew would linger long after the performance ended.

You begin the song wearing some black rimless wrap-around sunglasses, a black corset sweater with buckles attached to certain cutouts of the fabric, and a pair of very, very baggy cargo pants that bunch up in the ends as you wear some tall platform boots along with it.

Your boots added to your lengthy stature, as you were taller than all your members. So when you started the performance and strutted in front of the dancers and members, you held this model-like confidence that made fans watching you want to bob their heads along.

I'ma back up every word, yeah Mini skirt (Mini skirt), pretty pink What you heard? (What you heard?) But it's never what you think, trust

Yooyeon was also aware of your fluent English because you went to an international school, which you said in an interview.

With the rabbit hole, the visual fell through while learning about you and your group, and she got to know you fairly well without even speaking to you. The fact that you have a younger brother and sister, your favorite food and drinks are lemon iced tea and bossam, and you are 5’8, and even the fact that you learned how to dance at a dance academy.

It made her feel weird; an idol knowing several things about an idol despite not being friends with them made Yooyeon feel like a weird stalker. You stood in the center at the second chorus, dancing like you showed the MCs, but you were more serious about this.

Yooyeon stared at you as if you were some kind of siren, your eyes covered and looking dangerous, but the motions could be read by a glimpse at your lips. As if you called out to her, you kept rapping:

Heart attack, IV when I walk the street Vitamins that D, I'm good, I'm healthy

Followed by a twerking move that had the visual hiding the bottom half of her face with the use of her hands. She felt the heat rising to her cheeks as she watched the dance, her eyes never leaving your figure.

Finally, Haneul’s trending part was coming up, and you had to take off your sunglasses, acting as if you were cleaning them. Your eyes were covered in a darker, smokey eye look as your piercing gaze could be felt through the screen.

Once the chorus hits, you do the iconic choreography with the rest of the girls, mouthing Haneul’s lines as you then shake your head with your tongue out.

Yooyeon’s eyes never trail from the screen, and her hyperfocus is noticed by Nakyoung, who generally looks over the girls in the waiting room. “Be careful if you stare too hard. Your eyes might pop out,” she says, causing the older girl to flinch in surprise. Yooyeon looks over. Nakyoung had her mouth full of malatang, and an innocent grin formed despite her puffy cheeks.

“I wasn’t staring,” Yooyeon mumbles, and Xinyu butts in, “Oh, please, you couldn’t even fool a kid with that.” Nakyoung nods and takes another sip of her soup, “Do you like Y/n-sunbaenim?”

“First off, stop talking so much with your mouth full. Secondly, of course, I like her. They’re our seniors, after all,” that makes the 02 liners look at each other, giving knowing looks.

“You know she didn’t mean it in that way, unnie,” Yooyeon looked at Xinyu and just shook her head as the two giggled, deciding to focus back on her work.

“You know, for being a ‘fan,’ you seem to not know much about her,” Xinyu points out. The older girl looks at her, confused. Before she can ask what she means by that, it’s time to head on stage. Their manager does a quick headcount in the hallway, ensuring everyone is ready. As Yooyeon waits patiently in line, her attention shifts when, out of the corner of her eye, she notices you, Haneul, and Julie walking into view.

Her breath catches.

She freezes, deer-in-headlights, not expecting to actually see you in person. Sure, Yooyeon has seen you before—idols always run into each other—but this is different. She’s never seen you this close. And smiling. The sound of your laugh carries as Julie gestures animatedly, clearly cracking jokes while posing for you and Haneul.

Julie can’t seem to keep a straight face, breaking into laughter mid-pose. Your maknae lets out a sigh, still giggling. “Unnie~, we can’t stop laughing. Let me go first,” she whines, causing you to chuckle.

“Alright, alright.” You give her a gentle nudge, still smiling, your focus shifting briefly as Julie steps up.

Unintentionally, your eyes wander toward Yooyeon’s group.

Yooyeon quickly looks down, feeling her pulse quicken. ‘Don’t look, don’t look!’ she practically yells at herself, trying to act casual. But then her name is called for rolecall.

“Here!” she blurts, raising her hand on instinct.

It’s a mistake.

Her voice draws your attention.

Your gaze snaps to her, locking eyes before she has time to prepare. Yooyeon feels the heat creeping up her neck, her ears burning red as you wave and smile. It’s small and casual, but her stomach flips at the sight of it.

You think she looks cute, even though their stage outfits are supposed to exude confidence and power. Yooyeon is the only one who feels out of place in that moment, completely caught off guard.

Her group begins moving, but you suddenly dash forward, calling out to Nakyoung before they get too far.

“Hi!” you greet brightly, giving her a quick hug.

Nakyoung responds just as enthusiastically, chatting with you briefly before you return to your members.

Yooyeon stares after you, mouth slightly open in shock.

She hugged Nakyoung? She said hi like she knew her?

Yooyeon suddenly remembers Xinyu’s earlier words, and the realization hits her like a truck. Wait…

SHE KNEW HER?

The thought had Yooyeon pouting and kicking her feet like a sad child on their way to the stage.

Your eyes catch a glimpse of her face, and you find her puffy cheeks and pouty lips adorable. “Cute,” you mumbled as your members were lost in taking photos.

“Y/n, you’re up next,” Julie announces as Haneul gently nudges you towards the staircase. “Did you ask about Haerin?” The older asks, and you nod, “Nakyoung unnie said they won’t have a film schedule on Sunday, but they’ll be at the building, so I could meet them there.”

“Unnie~, can we all go? I haven’t seen Haerin-ie in a while,” Hanuel asks, her cute face pouting innocently as you pat her head. “We’re gonna have to ask manager-nim,” Julie nods, agreeing, and whips out her phone quickly to relay the message.

“It’s been a while since I've seen her,” you say, a heavy sigh leaving your lips. “I’m sure she misses you too,” Hanuel nods at her unnie’s words, “You know she loves you a lot, unnie.”

You smile, feeling more relieved as you think about it, “I get to see her in a few days anyways, no big deal.”

The news had you excited, but it was a struggle to keep it in. After a few more scheduled events throughout the day, the manager finally got back to Julie, giving all you guys permission to go, but only for a limited amount of time. That only gave you more excitement, having you bounce like a bunny in happiness late at night.

You thought of it as a short vacation. Given it’s extremely short, you wouldn’t spend your free time any other way.

It was now Sunday afternoon, and a select few older members of tripleS could be seen seated in a meeting room. Some staff and higher-ups were presenting updates on concepts and potential lineup plans.

With how the tripleS system worked, these meetings were routine, keeping every member in the loop. This time, it was the older girls’ turn to sit through the discussions.

Yooyeon sat near the corner, listening diligently until the meeting finally wrapped up, giving the group some free time. As the girls filtered out, Yooyeon joined Mayu, Xinyu, Nakyoung, and Sohyun, heading toward the practice rooms where the younger members were hanging out.

They walked through the building lobby when an audible gasp broke the casual chatter.

Yooyeon glanced over at Nakyoung, whose face lit up with an unmistakable smile, while Sohyun froze with her mouth slightly open. Curious, Yooyeon followed their gaze toward the main entrance, and stopped in her tracks.

There you were.

Natty, Julie, Belle, Haneul, and you were walking in, chatting and laughing. But all Yooyeon could focus on was you.

You even do anything to command attention, just walking in, yet it comes effortlessly to you. Her mind raced. Why are they here? Why is Y/n here?

Before she could understand, your eyes landed on Nakyoung, and your smile grew wide. You sprinted toward her, arms outstretched, pulling her into a hug that was as rough and yet warm.

“Oh my god, it’s been too long!” you exclaimed, laughing as Nakyoung let out an exaggerated groan.

“Well, it’s nice to see you too. Also, you just saw me like four days ago,” Nakyoung teased, patting your head while you clung to her like a koala.

“Y/n~, let Nakyoung go, please,” Natty called out with a laugh. You pouted in response but let go, your playful grin returning.

Yooyeon stood frozen.

This wasn’t the Y/n she had imagined. The confident, composed image she’d seen on stage and in videos was replaced with someone incredibly… cute. It caught her off guard. Her thoughts spiraled. Why does she seem even more attractive now?

A nudge from Xinyu snapped her out of it, and she quickly looked away, hoping no one noticed her staring.

“She’s upstairs in the practice room,” Nakyoung said warmly, glancing between you and the group. “We were just heading there. You guys can come with us.”

“Perfect timing,” you said with a grin, motioning for your group to follow them.

The ten of you squeezed into the elevator with ease, yet the space felt tighter than it was. You ended up toward the back, shoulder-to-shoulder with Yooyeon.

She was quiet, keeping her eyes fixed ahead, but you caught the subtle tension in her posture. Bowing slightly, you flashed her a polite smile. “Hi! Nice to meet you,” you said, your voice friendly yet calm and quiet.

Yooyeon’s heart stuttered in her chest. “H-hi,” she stammered, dipping her head in return. Her voice was barely audible, and she instantly hated how awkward she sounded.

It didn’t faze you, though. You leaned back slightly, still smiling, a casual ease about you that almost felt teasing. It wasn’t overbearing—it was just… natural.

Standing beside Yooyeon, Nakyoung noticed the interaction and bit back a chuckle. Her eyes flicked to Yooyeon’s face, which was already starting to flush.

“You good, unnie?” Nakyoung whispered, her tone laced with amusement.

Yooyeon nudged her with her elbow, her face turning an even deeper shade of red. “Stop,” she muttered under her breath, not daring to look at you.

The ride up felt endless yet too short for Yooyeon. Every small movement you made, brushing a stray strand of hair back, shifting your weight slightly, somehow caused her body to heat up with her brain in a frenzy. When the elevator finally chimed, she exhaled softly as if she’d been holding her breath the entire time.

The group filed into the practice room, and the noise inside died down almost instantly as the girls noticed you. Whispers filled the room until, from the far corner, an excited squeal rang out.

“Unnie!” SeoAh’s voice was unmistakable. She bolted across the room, throwing herself into your arms with a force that nearly toppled you.

“Haerin!” you laughed, hugging her tightly. “Oh my god, it’s been forever!”

She pulled back just enough to look at you, her eyes wide with a mix of excitement and disbelief. “You didn’t tell me you were coming!” she pouted her lower lip jutting.

“Surprise?” you teased, grinning as she playfully smacked your arm.

Yooyeon lingered near the doorway, watching the reunion unfold. Her brows furrowed as she processed the scene.

“Wait,” she whispered to Nakyoung. “That’s her sister?”

Nakyoung smirked knowingly. “You didn’t know? Some fan you are,” she teased, nudging Yooyeon’s side.

Yooyeon’s jaw tightened as embarrassment flooded her system. She glanced back at you, her thoughts racing. Haerin was your sister?!

After catching up with SeoAh, you turned to the rest of the room, clapping your hands together. “Alright, let’s make some TikToks! Who’s in?”

The energy in the room shifted immediately. Girls paired off into groups, the buzz of excitement contagious.

Julie teamed up with Xinyu and Nakyoung, their sharp, synchronized moves to a Performante drawing cheers. Natty and Haneul joined Sohyun and Dahyun for Girls Never Die, hyping each other up with exaggerated moves and laughter.

Meanwhile, you pulled SeoAh aside for a cuter rendition of Get Loud. The two of you added silly gestures between the choreography, giggling when one of you missed a beat. The room was filled with laughter as the other girls watched, your easy dynamic with SeoAh radiating warmth.

When you wrapped up the TikTok, SeoAh turned toward Yooyeon with a mischievous glint in her eye. “Unnie,” she called out, her grin widening. “You should do Igloo with Yooyeon. She knows it really well!”

Yooyeon froze, her eyes widening in panic. “What?”

You turned to her, tilting your head slightly, curiosity flickering in your expression. “You know Igloo?”

Yooyeon swallowed hard. “Uh… yeah, I guess…” she mumbled, her voice betraying her nerves.

“Perfect!” you said brightly, stepping toward her. “Let’s do it together.”

Her pulse quickened as you stood beside her. Your presence was undeniably charming. You were calm and effortlessly made friends. Yet, your deep tone made it hard for her to feel completely intimidated.

Sensing her hesitation, you leaned in slightly, lowering your voice so only she could hear. “Don’t worry,” you said with a soft smile. “It’s just for fun. If you mess up, I’ll mess up too, so we’re even.”

Your words were simple, but they worked. She nodded, exhaling a shaky breath. “Okay,” she said quietly.

As the music started, you moved first, setting the rhythm. Yooyeon followed, her movements hesitant but growing more confident with each step. You threw in a few exaggerated gestures, making the others laugh, and Yooyeon found herself smiling despite her nerves.

When she nailed one of the trickier transitions, you clapped for her mid-dance, your encouragement genuine. “See? You’ve got this!” you said, your grin infectious.

By the time the song ended, Yooyeon’s heart was racing—not from the choreography, but from you.

You weren’t just talented; now, you were approachable, funny, and incredibly kind. Every interaction chipped away at the wall she’d unknowingly had up, leaving her feeling completely smitten.

As the room erupted in applause, you turned to her with a wink. “Told you it’d be fun.”

Yooyeon nodded, her cheeks burning. “Yeah… it was,” she admitted softly.

But inside, all she could think was, What have I gotten myself into?
