AUTHOR'S POV

The hum of fluorescent lights blended with the rhythmic tapping of keyboards in the 19th-floor office of Hope Industries. A floor-to-ceiling glass window stretched behind YN’s desk, letting in golden sunlight that softened the harsh lines of corporate chaos. The office smelled faintly of brewed coffee, ink, and professionalism — everything Choi YN had grown used to over the last two years as the personal executive assistant to CEO Jung Hoseok.

She was good at her job. Efficient. Organized. Always early. She had learned Hoseok’s mood patterns, how he liked his coffee, how he preferred email over in-person reports unless it was critical. And most importantly, how to keep emotions out of work.

Except lately... she’d been struggling with that.

Not because of Hoseok.

But because of him.

She hadn’t even realized he was there — until she looked up through the translucent glass panel separating her desk from the hallway. At first glance, he seemed like a shadow. But that stance, that aura… It was him again.

Jeon Jungkook.

He wasn’t supposed to be here. Not this often. He wasn’t a part of the company. He was just Hoseok’s younger stepbrother — a college kid who occasionally dropped by with ramen or left his helmet in the lounge when visiting.

Yet, for the third time that week, there he was… leaning lazily against the corridor wall, wearing his favorite white oversized hoodie, hood half-down, a strand of inky black hair falling across his forehead, lip ring catching the light. His backpack hung from one shoulder, and a single earbud rested in one ear.

He was looking straight at her. Not smiling. Just watching.

YN froze for a heartbeat, heart stumbling in her chest. She quickly pretended to be busy with her keyboard. Her fingers trembled slightly, but she masked it with practiced calm.

Why was he always watching her like that?

Across the Hall

Jungkook felt the corners of his lips twitch when she tried to ignore him. She always did that — looked at him for a second too long, and then immediately pretended he wasn’t there.

But he knew better.

He saw the way her breath paused when their eyes met. The way she straightened her spine, tucking her hair behind her ear in that nervous little motion.

She was beautiful in a soft, quiet way. The kind of beauty that didn’t scream for attention. The kind you noticed when the world slowed down — like the comforting warmth of sunlight after weeks of grey.

Choi YN.

His brother’s right hand. Always composed. Always dressed in muted colors — beige, navy, ivory. He liked that about her. There was nothing fake about her.

And that made her the only real thing in this fake, plastic world he hated.

“Still staring, huh?”

Jungkook didn’t even blink when Hoseok appeared beside him.

“She’s... different,” Jungkook said, voice low.

Hoseok followed his gaze and smiled knowingly. “She’s seven years older than you, Jungkook.”

“Twenty-five is not old.”

“You’re eighteen.”

“I’m not a child.”

Hoseok chuckled. “No, you're not. But she works for me. And she's way out of your league.”

Jungkook’s jaw clenched slightly, not liking the possessive tone his brother used — as if YN were a thing to be claimed.

“She’s not anyone’s property,” Jungkook said quietly.

Hoseok raised an eyebrow, a little surprised. “That’s not what I meant, kid.”

“Don’t call me that.”

There was a pause between the brothers — a long, unspoken history neither liked to discuss. Stepbrothers by name, strangers by childhood. Hoseok had grown up with everything.

Jungkook with very little. Only recently had their broken families attempted to blend.

And yet... here they were. Sharing blood, office hallways, and maybe — unknowingly — feelings for the same woman.

---

YN exhaled slowly once Hoseok and Jungkook disappeared around the corner.

Why does he keep showing up? Why does he look at me like that?

He was just a boy.

Right?

But no matter how many times she told herself that, her heart never seemed to listen.

---

NEXT MORNING......

The morning rush at Hope Industries was always predictable — people in tailored suits carrying tablets, assistants rushing with files, phones ringing in synchronized chaos, and the aroma of caffeine lacing the air like perfume.

YN moved gracefully through it all, one hand holding her notepad, the other wrapped around a tall paper cup of black coffee. The scent calmed her nerves — her morning ritual before facing another long day of deadlines and meetings.

She stepped out of the executive elevator and into the hallway, heading toward her desk outside Hoseok’s office. Her heels clicked softly against the marble, and her mind drifted — back to him again.

Jeon Jungkook.

Ever since their unexpected eye contact yesterday, she hadn’t been able to shake the image of his piercing gaze. There was something unsettling in how he looked at her — like he was reading every thought she tried to hide.

Snap out of it, YN. He’s just a kid.

She shook the thought away and turned the corner—

Crash.

Hot liquid exploded between them as her coffee cup was crushed mid-step, sloshing all over her blouse and splattering across a black hoodie.

“Oh my god—” YN gasped, stepping back.

And then she looked up.

Wide eyes. Long lashes. A little silver ring glinting on his lower lip.

Him.

He stood frozen, half-laughing, half-horrified. “Shit—sorry! I didn’t see—”

“Jungkook?” she blinked, eyes wide in recognition.

He froze. And then the smallest smile curved on his lips.

“Noona remembers me now.”

---

They both stood in the middle of the hallway, soaked in coffee, staring at each other like time had stalled around them. She was the first to react —

quickly setting down her bag and dabbing at her shirt with tissues from her notebook.

“You’re okay?” he asked, voice a little softer now. “It didn’t burn you, right?”

“I’ll live,” she muttered, more flustered by his closeness than the actual spill.

Jungkook stepped forward, his hands awkwardly reaching out, unsure whether to help or not. “Here—wait—at least let me clean your—”

“No, it’s fine. I’ll just—” Her eyes met his again. And that’s when she really noticed.

The way he looked now.

He wasn’t the teenage troublemaker crashing company parties anymore. He’d grown. His jawline was sharper, his hair a little longer, his frame taller — but it wasn’t just that. His presence had changed. There was a calm confidence in the way he stood now, like he no longer needed to prove anything.

“You grew up,” she said without meaning to.

Jungkook raised an eyebrow, lips tugging into a playful smirk. “You noticed?”

She quickly cleared her throat, stepping away. “I should go change. Hoseok-ssi has a meeting soon—”

“You always call him Hoseok-ssi,” Jungkook interrupted, teasing. “So formal.”

“He’s my boss.”

“I know,” he said, gaze dropping briefly to her hands. “But I’m not.”

---

YN laughed nervously, backing away toward the staff lounge. “Still a clumsy kid, I see.”

“I said I was sorry!”

“And I’ll add it to your list of offenses,”

she smiled, just a little. “Bye, Jungkook.”

He stood there, watching her walk away, her shoulders tensed in embarrassment, her blouse stained with coffee — and still, to him, the most breathtaking sight in that building.

He whispered to himself with a crooked smile,

“Definitely not a noona I can forget.”

---

YN sat near the office window with a warm tea in her hand, chatting with Soojin, a fellow executive from HR. The meeting was over, Hoseok was out for lunch, and for once, the office had a bit of calm.

They were talking about their college days — the fun, the fashion, and the kind of men they used to crush on.

“You know what I’ve always found insanely hot?” Soojin said, leaning closer with a grin.

YN sipped her tea. “Hmm?”

“Men with lip piercings. Like... the subtle kind. Just one, you know? Right here—” She pointed to her lower lip. “It screams soft but dangerous.”

YN chuckled, “Yeah, I get that. It’s such a specific kind of hot. Like... bad boy but quiet version.”

“Exactly!” Soojin lit up. “Don’t tell me you’re into that too?”

YN shrugged with a teasing smile. “I mean... I wouldn’t say no.”

Neither of them noticed the figure who had just turned the corner.

A figure who was not supposed to be there.

But was.

Jeon Jungkook.

His hoodie half-zipped, backpack hanging off one shoulder.

Standing there.

Frozen.

Lip piercing.

Hot.

Wouldn’t say no.

His heart. Literally stopped.

Fifteen Minutes Later – Hoseok’s Office

Hoseok didn’t even get to sit fully in his chair before Jungkook burst into the room.

“Hyung!”

“What now—?”

“Please talk to mom for me!” Jungkook said urgently, dropping his bag and running a hand through his hair like it was a crisis.

Hoseok blinked. “Wait, what happened? Did someone die?”

“I want a lip piercing!” Jungkook blurted. “Please convince mom! She’ll listen to you, you know she listens to you when it’s something serious.”

Hoseok leaned back in his chair, frowning. “You barged into my office for that? A piercing?”

“It’s important, hyung!”

Hoseok squinted at him. “You don’t even like piercings that much. What happened to you saying, ‘I’m not like those attention-hungry punks’?”

“That was before,” Jungkook muttered, cheeks a little pink.

“Before what, exactly?”

Jungkook hesitated.

Then... he folded his arms and said quickly:

“YN said she finds guys with lip piercings hot.”

Silence.

Hoseok blinked once.

Twice.

And then burst out laughing.

“You’re kidding me—”

“I’m serious!” Jungkook whined. “She said it! I heard her! I was walking past her and Soojin noona. She said it casually but like—her voice was so soft and she smiled and dammit hyung, she’d probably notice me more if I had one!”

Hoseok was practically crying now. “You're down bad, Jungkook.”

“I am!” he shouted, pacing now. “I think about her all the time. She always calls me a kid but if I had a piercing maybe she wouldn’t—she’d look at me like... you know—like a man, not just your bratty stepbrother!”

Hoseok wiped his tears of laughter and tried to calm himself. “Look, I’ll try. But mom’s still traditional, and if she says no—”

Jungkook leaned over the desk dramatically, clutching his brother’s shoulders.

“Please, hyung. For love. For lips. For noona.”

“God, you’re pathetic.”

“I know!”

---

It had been four days since Jungkook had barged into Hoseok’s office, pleading for the one thing he never knew he’d want so badly — a lip piercing.

Hoseok had rolled his eyes, but surprisingly… he helped.

One call.

A half-hearted talk with their mother.

And a reluctant: “Fine. Just don’t come home crying if it gets infected.”

That was all Jungkook needed.

The Transformation

---

On Friday afternoon, Jungkook walked into the office building — but this time, he didn’t look like the chaotic, hoodie-wearing boy who used to linger outside Hoseok’s cabin with his headphones and his messy hair.

No.

Today... he looked different.

His hair was styled — dark, slightly wavy, parted to the side in a way that framed his face perfectly. He wore black jeans, a fitted black t-shirt tucked neatly under a leather jacket, and his silver chain peeked out subtly at the collar.

But the real change?

That small, silver ring now sitting on the left side of his bottom lip.

Glinting. Daring.

Dangerous.

The front desk staff paused. A couple of interns whispered.

Even Hoseok, who was in a meeting, peeked through the glass and muttered with a smirk,

“Oh god. He really did it.”

---

From her desk,YN was scribbling notes into a meeting folder, cross-checking figures when the elevator doors opened — and suddenly, a strange silence settled in the room.

She looked up.

And there he was.

Jeon Jungkook.

But not the one she knew.

He walked in with calm confidence, one hand in his pocket, earbuds gone, posture straighter, darker — cooler.

The black clothes hugged his frame just right. His jaw looked sharper. His eyes a little colder.

And then — she saw it.

That tiny silver ring gleaming on his lip like a dare.

A little crooked smile playing just beneath it.

Her heart skipped.

But she didn’t say anything.

She looked down quickly, hiding the flush creeping up her cheeks.

Still, her thoughts screamed louder than she could silence them:

“Damn it... he’s hot.”

---

Jungkook saw it.

That flicker in her eyes.

That half-second pause in her breath.

She noticed.

But she didn’t say a word.

He almost laughed.

Walking past her desk, he slowed just a little, leaning in casually as he said:

“Afternoon, noona.”

His voice — lower. Rougher. Confident.

YN didn’t look up, pretending to stay focused on her file.

But he saw her fingers curl slightly.

Her lips twitch.

Her ears turn red.

---

Inside Hoseok’s Office......

“You seriously did it,” Hoseok said, sipping his coffee with a smirk as Jungkook flopped down on the couch across the room.

“Told you I would,” Jungkook replied, tossing his leather jacket aside and running a hand through his hair.

“And the wardrobe change? Who are you trying to be? BTS’s maknae or a rockstar?”

Jungkook grinned. “Neither. Just… someone she might notice.”

Hoseok raised a brow. “She already noticed. I saw her blush, you idiot.”

Jungkook stilled for a second.

“Really?”

“She didn’t say a word though,” Hoseok added, amused. “Classic YN. Pretend she’s not dying inside.”

Jungkook smiled softly to himself.

“Good,” he whispered. “Let her feel it a little.”

---

Outside, Later That Day......

As Jungkook leaned against the office wall near the elevators, waiting for Hoseok to finish his meeting, he watched as YN walked past again — arms full of files, heels clicking with elegance.

Their eyes met — briefly.

She didn’t smile.

She didn’t comment.

She just looked.

But her gaze lingered one second too long on his lip ring.

He smirked.

And whispered under his breath:

“Let the game begin, noona.”

---

TIME SKIPS......

The office was unusually busy that day — quarterly reports, client meetings, presentation decks flying across tables. YN had barely taken a sip of her morning coffee when Hoseok called her in.

"YN, come inside. Bring your laptop too."

She walked into his spacious office, finding him at the conference table instead of his usual desk.

“You’ll sit here beside me today. I need someone sharp on hand,” Hoseok said, tapping the seat next to his.

She blinked. “Sir, are you sure? I can take notes from outside—”

“I’m very sure,” he interrupted with a mischievous grin. “Right here. Close. So I don’t miss a single detail.”

She smiled politely, unaware of his real intentions.

Because across the room — slouched on the leather couch, one leg over the other — sat Jeon Jungkook, earbuds out, head tilted, watching every move.

His brows knit slightly when YN sat beside his brother.

And even deeper when Hoseok leaned a little too close to show her something on the screen.

And then he started whispering things in her ear, just to “explain the numbers.”

Jungkook’s jaw clenched.

What the hell is he doing?

---

“YN, you always smell nice. What perfume is this?” Hoseok said playfully mid-meeting.

“Ah—just something floral,” she replied shyly.

Jungkook narrowed his eyes.

Flirting? Really, hyung?

“Hmm. Suits you,” Hoseok added, just loud enough for Jungkook to hear.

The younger boy shifted in his seat, arms crossed now, glaring.

“Should I order lunch for us?” YN asked.

“Oh yes, just for us two,” Hoseok said loudly, smirking toward the couch. “The rest can figure it out.”

Jungkook practically shot out of his seat.

---

Later That Day.......

The moment YN left to attend a different department call, Jungkook stormed into Hoseok’s cabin and slammed the door behind him.

“Hyung!” he whined.

Hoseok looked up, totally unfazed. “Oh hey. Enjoyed the show?”

Jungkook glared. “Why were you flirting with her like that?!”

Hoseok leaned back in his chair, smirking. “I wasn’t flirting. I was demonstrating your future suffering.”

“You made her sit beside you!”

“She’s my assistant.”

“You whispered in her ear!!”

“I was pointing out chart errors.”

“You said she smells good!” Jungkook’s voice cracked slightly in outrage.

“Well, doesn’t she?”

Jungkook let out the most dramatic groan, throwing himself onto the chair and burying his face in his hands.

“Hyung, this isn’t funny! I’m literally fighting for my life here and you’re just—just being a troll!”

Hoseok laughed so hard he almost dropped his pen. “You should’ve seen your face when she giggled. I thought you were gonna combust.”

“I almost did!” Jungkook snapped, lip jutting into a full pout now. “You know I like her, hyung. Don’t do this to me.”

“Relax, kid,” Hoseok said, still grinning. “I was just testing something.”

“Testing what?”

“If she reacts when you’re jealous.”

Jungkook blinked. “Did she?”

“Oh, definitely,” Hoseok leaned forward with a secretive grin. “She didn’t like me being close either. Her eyes flicked toward you more than once. You’re in her head, little bro.”

Jungkook straightened, cheeks slightly pink now. “You’re serious?”

“Dead serious. But now it’s your move.”

Jungkook’s pout turned into a slow smile.

---

As YN gathered her things at the end of the day, she caught Jungkook watching her again — standing beside the elevator, lip ring between his teeth, black shirt sleeves rolled up.

He didn’t say anything.

Just stared.

And then finally spoke:

“You should sit beside me next time, noona.”

YN froze — heart skipping again.

“Why?”

He smirked, leaning a little closer.

“Because I smell nice too.
