The afternoon sun had already started its descent, casting a honeyed glow over the parking lot of Yonsei University. The air was crisp, carrying the faint scent of roasted chestnuts and autumn leaves. Students were beginning to flood out of the buildings, buzzing in pairs and groups, laughing about lectures and weekend plans.

Jungkook stood by the car-sleek, matte black, its doors open and waiting-like a statue sculpted in silence. He leaned slightly against the rear door, arms folded, eyes hidden behind dark tinted sunglasses. His jaw was tight, and his posture screamed quiet vigilance.

Then, he saw her.

YN was walking toward him, adjusting her bag strap as she approached. Her hair had gotten a little messy in the wind, cheeks pink from the cold. She was scrolling through her phone, completely unaware of the storm brewing in the man who waited for her.

And then, like fate taunting him-

"YN!"

It was him again.

Mark.

Jogging up with that same too-eager grin, his hoodie sleeves pushed up, tablet tucked under one arm. His sneakers squeaked slightly as he caught up with her.

Jungkook's fingers twitched.

"Hey, hey-sorry to stop you again,"

Mark said breathlessly. "I just realized I didn't save the last file we were working on. Could you text it to me later?"

"Sure," YN said with a casual smile. "I'll check when I get home."

Mark nodded-then, without warning-he leaned in and hugged her.

Right in front of Jungkook.

It wasn't tight.

It wasn't romantic.

But it was too familiar.

Too easy.

Jungkook's breath caught in his throat.

He didn't move.

Didn't speak.

But his fingers clenched into fists, the leather of his gloves creaking slightly from the pressure.

And then-

"Mark," YN said, pulling back with a light shove. "Don't hug me like that. I don't like it."

Mark blinked, clearly embarrassed. "O-oh. Sorry, I just... I mean, we always-"

"We used to," she said, suddenly serious. "That doesn't mean I'm okay with it now."

He held up both hands in surrender. "Got it. Sorry. No hugging."

She nodded, tone firm but not unkind.

"Text me later, okay?"

"Sure, yeah," Mark said, rubbing the back of his neck awkwardly before turning and walking away.

Jungkook said nothing as she approached. He just opened the car door for her. She climbed in silently, and he followed, settling into the driver's seat with practiced calm.

But inside?

He was a storm.

He wasn't supposed to care.

She wasn't his anything.

She was the daughter of the man he was meant to destroy.

So why...

Why did it sting?

--

The car ride was quiet at first, soft music playing from the stereo. YN sat with her cheek against the window, fingers drumming against her knee. She glanced at Jungkook from the corner of her eye-his hands steady on the wheel, expression unreadable.

And then, suddenly-

"Ice cream."

Jungkook blinked. "What?"

"I want ice cream," she repeated, sitting up straighter.

"It's cold outside," Jungkook replied.

"You'll catch a chill."

"You're not my dad."

"No, but I'm the one who'll have to deal with your whining if you get sick."

YN pouted. "I haven't had dessert all day."

"You had peach jelly last night."

"Not the same."

Jungkook exhaled through his nose. "I don't eat ice cream. It messes with my throat."

"I didn't say you had to eat it. Just take me to get one."

Silence.

Then, with a sigh that sounded far more dramatic than necessary, Jungkook turned the car onto a smaller street, heading toward a quiet little dessert cafe tucked behind a row of boutiques.

--

Ten minutes later, YN was sitting on a stone bench just outside the café, swinging her legs slightly like a kid, a tall cone of double-scoop strawberry-vanilla swirl in her hand. Jungkook stood next to her, leaning against a pillar, arms crossed, eyes scanning the street like a trained hawk.

She held the cone close to her mouth, enjoying every bite with exaggerated joy.

"You're seriously not gonna have any?" she asked, licking the side of her cone.

Jungkook shook his head. "No."

"C'mon," she grinned. "Live a little."

"I don't need sugar."

"Are you allergic to happiness?"

"No," he said flatly, "I'm allergic to head colds and sore throats."

She giggled.

Then-without warning-she held the cone out to him. "One bite. Pretty please."

He turned to look at her.

Her eyes sparkled. Her bottom lip jutted in a perfect pout. And there it was again-that strange warmth in his chest that made him want to roll his eyes and pull her close at the same time.

He looked away. "No."

"One bite," she sang softly. "Just one."

He turned back to her slowly. Then, to his own surprise, he leaned down and took a small, careful bite from the top of her cone.

The cold hit his tongue instantly-sweet, soft, unexpected.

YN's eyes widened like a child who just won a prize. "Ha! I got you to eat it!"

He licked his lips, expression unreadable. "...It's decent."

She laughed. "You're impossible, Jeon Jungkook."

And he didn't reply. He just stood there, watching her smile like it was something he hadn't seen in years.

And maybe, just maybe...

He didn't want this moment to end.

---

The iron gates of the Choi mansion slowly creaked open, revealing the long pathway bathed in warm yellow lights that lined the drive like stars guiding them home.

The car rolled forward smoothly, its engine a low hum beneath the silence that had settled after the ice cream detour. YN was still smiling faintly, resting her head against the window. Jungkook remained silent, one hand on the wheel, his other arm relaxed, though his mind was alert.

Everything seemed... peaceful.

Until they pulled up to the main steps.

And YN froze.

There, standing under the grand porch lights, was a man.

Not a stranger.

Not a guest.

But a ghost from her past.

"...Grandpa?"

The word barely escaped her lips as she stared at the fragile figure standing in front of the tall mansion doors. He wore a long grey cardigan over a pale blue shirt, his shoulders slightly hunched, white hair neatly combed back. A worn cane rested lightly in his hand.

Her heart skipped.

She was out of the car before the driver even opened her door. Her heels clicked against the stone, her voice trembling with disbelief.

"Grandpa!" she called again, louder this time, breath catching in her throat.

Choi Il-Seong turned slowly, his soft eyes widening.

And then-like time folding in on itself-she threw her arms around him.

"YN-ah," he whispered, wrapping his arms around her, his voice cracking. "My little girl..."

Tears spilled freely down her cheeks. "I thought I'd never see you again. I missed you so much..."

Jungkook stood near the car, silently watching the reunion. He didn't move.

Didn't speak.

He just... watched.

She looked up at her grandfather, still crying but smiling, overwhelmed.

"Did... did Dad bring you here?"

Choi Il-Seong paused.

He looked up-his eyes met Jungkook's for the briefest moment. Jungkook gave the subtlest shake of his head. A silent agreement.

The old man smiled instead.

"Something told me... it was time."

FLASHBACK - 24 Hours Earlier

Location: A hidden warehouse, Outskirts of Busan

The wind howled along the abandoned fishing docks, the warehouse creaking like an old memory. Inside, dim lanterns lit up the space, casting long shadows against rusted machinery and wooden crates.

Taehyung stood near the far wall, arms crossed over his chest, glancing at his watch.

"He'll be here any second."

The back door opened-and Jungkook stepped in.

Dressed in all black, his coat billowing behind him, eyes sharp, unreadable.

"You found him?" Jungkook asked.

Taehyung nodded. "Living alone.

Minimal contact with the village.

Surviving off his late wife's pension. Health is fragile."

Footsteps echoed behind them as an older man entered, led by a cautious villager. His cane tapped against the concrete floor, and his gaze flicked between the two strangers.

"You're the ones who called for me?"

Choi Il-Seong asked, voice wary. "Who are you?"

Jungkook stepped forward. "My name is Jeon Jungkook. I work under Choi Sejin-as your granddaughter's bodyguard."

The old man's eyes narrowed. "Sejin sent you?"

"No," Jungkook replied quietly. "He doesn't know I'm here."

Il-Seong looked between Jungkook and Taehyung, confused. "Then why are you here?"

Jungkook stepped closer, his tone even.

"Because your granddaughter hasn't stopped missing you for two years. Because every night she holds onto your memory like it's all she has left of her mother. And because no matter what Sejin told you... she needs you."

Il-Seong's throat bobbed. "I thought... he didn't want me near her."

"He doesn't," Jungkook said bluntly.

"But I do."

The old man looked stunned. "Why would you want that?"

For the first time, Jungkook faltered. Then he spoke quietly, eyes not meeting his own.

"Because no one deserves to live buried while they're still breathing. And no child deserves to cry themselves to sleep when the person they need most is still alive."

Silence.

Choi Il-Seong slowly sat on an old crate, shoulders trembling. "I thought she forgot me."

"She never did," Jungkook said. "She's just been made to believe she couldn't fight for you."

The old man wiped his eyes slowly.

And then-he nodded. "Take me to her."

Taehyung raised a brow, slightly stunned. "Just like that?"

Il-Seong gave a small smile. "A grandfather knows when he's needed. And if she still remembers me... I won't waste another second."

PRESENT DAY - Choi Mansion

That same old man now stood in the grand halls of the Choi estate, surrounded by luxury, but all he saw was her-the girl who still remembered his lullabies, the girl who used to sit on his lap while he read her bedtime stories.

YN held his hand tightly as she led him into the sitting room, tears still trailing down her face.

"I have so much to tell you," she whispered, voice cracking.

"And I'm here to listen," he replied, brushing her hair back gently.

From across the room, Jungkook stood still, his heart a mixture of peace and confusion.

He hadn't done this for the mission.

He hadn't done it to hurt Sejin.

He did it... for her.

And that was the most dangerous thing of all.
