The quiet of her house felt like a warm cocoon as Yn folded the last of her clothes into the suitcase. She was finally ready. A soft smile danced on her lips. Things were finally falling into place… or so she thought.

DING-DONG!

The sudden loud chime made her heart jump. Smiling faintly, she headed toward the door, brushing her hands against her hoodie.

But the moment she opened it—

her smile froze.

There he was.

Kim Taehyung.

Standing tall, face unreadable, eyes darker than night—but there was something off. Something broken in those eyes.

“No.” Yn muttered, panic flaring in her chest. Her hands shot forward to slam the door shut, but—

Thud.

He wedged his boot in the gap.

“Get the hell out!” she screamed, struggling with all her might to close it, but Taehyung was stronger. He shoved his way in, and Yn lost her balance, falling hard against the floor.

Before she could react, he was already kneeling beside her, reaching out—

“Don’t touch me!” she spat, pushing him away.

His brows furrowed, hurt flashing in his eyes. Still, he grabbed her arms and yanked her to her feet.

“Yn, listen—”

“Let me go!” she thrashed against his hold, fists pounding against his chest.

“What the fuck are you doing here?! Get out!”

But Taehyung didn’t flinch. He took the hits without a word, then suddenly cupped her face in a vice-like grip, forcing her to look at him.

“LOOK AT ME!” he growled.

Her breath hitched.

For the first time—

Kim Taehyung was crying.

Tears welled up in his usually cold, composed eyes, and he looked like a man barely holding himself together.

He shut his eyes, took a deep breath, and murmured, almost brokenly,

“You’re not safe with Jungkook.”

Yn stared in disbelief. Then fury took over.

“I LOVE HIM, TAEHYUNG!” she screamed, shoving him back, chest heaving.

“Why the fuck can’t you understand that?!”

Taehyung’s jaw clenched. “And I love you, damn it—”

But she cut him off with a bitter laugh.

“You don’t love me. You never did!” Her voice cracked, soaked in betrayal. “You don’t even know what love is! You only know how to hurt people.”

“Yn—”

“GET THE HELL OUT OF MY HOUSE! OR I SWEAR, I’LL CALL THE COPS!”

She stormed to the door, swung it open, and turned back.

Taehyung stood there, frozen. Head bowed. Silent.

Then, he slowly lifted his gaze, pain etched deep in every line of his face.

“You don’t believe me… but I’ll prove it. Everything.” His voice was quiet but deadly serious.

“Just wait and watch.”

Without another word, he turned and walked away.

The low growl of his engine moments later confirmed he was gone.

Yn slammed the door shut. Locked it. Then slowly slid down, her back against the wood, chest trembling.

Tears slipped down her cheeks before she could stop them.

“Why now…” she whispered. “Why, when I thought things were finally okay…”

But she wiped her tears away with the back of her hand. “No. I trust Jungkook. He’s changing. He’ll be better. For me. For us. I love him. That’s all that matters.”

She zipped her bag, grabbed her keys, and stepped outside.

And froze.

There, leaning against his car like he owned the night—

Jeon Jungkook.

Arms folded. Expression unreadable. Dark eyes pinned on her. Waiting.

Sweat beaded on her forehead. Did he know? Did he see?

But he walked toward her in slow, measured steps. Took the bag from her without a word.

Then, finally—

a soft smile curled his lips.

“You got everything, baby?”

Relief flooded her chest. She managed a shaky smile. “Y-Yeah… it’s enough for now.”

“Good,” Jungkook murmured, his voice low and velvety. He snaked an arm around her waist, pulling her close. “Let’s go. It’s almost dinner time… and I’m starving.”

As he led her to the car, she swallowed the knot in her throat.

She didn’t tell him about Taehyung.

Not yet.

But what she didn’t know…

was that Jungkook had already seen everything.

And he was always one step ahead.

Author 's POV

A cold, dimly lit evening in the Kim mansion. The spacious living room is silent, except for the occasional tick of the wall clock and the soft crackling from the fireplace. Mr. Kim is seated on a leather armchair, a glass of untouched whiskey resting on the table beside him, his gaze fixed on the flames dancing before him.

Mr. Kim's POV:

Mr. Kim sat motionless, shoulders slightly slumped forward, brows furrowed deeply as if the weight of his thoughts could crush him. His fingers tapped absentmindedly against the armrest. Jungkook’s warning… that look in his eyes… It wasn’t the first time Jungkook had issued a threat, but this one—this felt different.

"The way he choked Taehyung… That wasn’t normal. That was personal. That was rage masked under years of silence."

He inhaled sharply, trying to erase the memory. But no matter how many times he blinked, the image of Taehyung struggling under Jungkook's grip haunted him.

"My son… my only son…" he muttered to himself. “How did it come to this?”

There was a darkness in Jungkook—always had been. Calm on the outside, dressed in the skin of a powerful businessman, respected and refined… but the few who truly knew him, really knew him, understood the monster that coiled beneath that suit.

Yes, the world didn’t know it—but Mr. Kim did. Taehyung did. Jungkook… was Taehyung’s stepbrother.

And the past was not kind.

“And now… it’s Yn.”

His grip tightened on the armrest. Jungkook had Yn in his possession. He hadn’t hurt her, not yet. But it was only a matter of time. And if Taehyung acted out of anger, things would spiral out of control. Jungkook wasn’t someone they could afford to provoke.

Suddenly, a loud car horn snapped him out of his thoughts.

Mr. Kim stood up instantly, eyes narrowing toward the front of the mansion.

"Taehyung.”

Within seconds, the door swung open. A tall figure stepped in, shoulders tense, footsteps heavy. Taehyung’s jaw was clenched, his eyes—bloodshot, furious.

Mr. Kim: "Taehyung..." He stepped forward, placing himself in front of his son. "Look at me."

But Taehyung didn’t. His eyes darted past his father, lips trembling with rage he couldn’t contain. His fists were clenched so tight, the knuckles had gone pale.

Mr. Kim raised his hand and gently cupped Taehyung’s face, tilting it upward until their eyes met. He sighed.

Mr. Kim : "Your eyes… You're losing yourself, son. I told you not to go to her, didn’t I? Yn didn’t listen, did she?"

Taehyung gave a small, almost broken nod.

Taehyung gritted his teeth and said,

"She pushed me away. She… she told me to leave, Appa."

His voice cracked at the end. Mr. Kim felt it—the raw hurt beneath his son’s fury.

Mr. Kim:

"She doesn't know the truth yet, and that’s dangerous. Jungkook hasn't told her anything about the two of you… about our past. If she finds out from him, it could destroy everything."

Taehyung’s lips parted, but no words came. His rage was buried under layers of helplessness.

Mr. Kim tightened his hold on Taehyung’s shoulders, eyes stern now.

Mr. Kim: "We’ll get her back. But we’ll do it my way. No more reckless moves, Taehyung. You follow my instructions—every single one. And then, you can have Yn. Do you hear me?"

Taehyung stared at his father. His chest heaved with heavy breaths, but he nodded.

Taehyung:

"I’ll do whatever it takes."

Without another word, Taehyung turned and walked up the stairs, the echo of his boots haunting the silence that returned to the mansion.

Mr. Kim stood there, staring at the empty staircase.

"What are you doing to him, Yn…" he whispered under his breath, his heart aching.

Jungkook’s POV

The engine purred softly as he drove, one hand on the wheel, the other resting possessively on Yn’s thigh.

She sat beside him, quiet—too quiet. Her eyes flicked out the window, her fingers fidgeting with the hem of her sleeves.

He noticed everything.

He always did.

She didn’t say anything about the uninvited visitor at her door.

But Jungkook already knew.

His men had called him the moment Taehyung entered her street.

And Jungkook had watched—every second of it.

From the hidden camera he planted in her hallway last week.

The screams.

The crying.

The confession.

He had watched Taehyung touch his woman.

Hold her.

Cry for her.

And Jungkook smiled.

Not the sweet smile he gave Yn. No, this one was twisted, venomous—one that would chill anyone to the bone.

“Taehyung…” he muttered under his breath, voice like poison. “You finally cracked, huh?”

Yn stirred beside him. “Hmm?”

Jungkook smiled sweetly and shook his head. “Nothing, baby. Just talking to myself.”

She nodded and returned her gaze to the road. She looked so soft. So innocent. So fragile.

He could almost laugh.

She thought she chose him. She thought she was free.

But Yn didn’t realize she was already caged.

And Jungkook held the only key.

Time skips

Later that night, after Yn fell asleep as he purposely mix sleeping pills on her food and it didn't took her time to feel asleep tangled in the sheets he’d wrapped around her like a shield—

Jungkook sat in his private room, watching the recorded footage again.

Taehyung’s trembling voice echoed through the speakers.

"I love you, damn it—"

Jungkook leaned back in his chair, a silver dagger twirling slowly between his fingers. His smile was gone.

His eyes were cold now.

“You love her?”

He spoke to the screen like Taehyung could hear him.

“Too late.”

He stood up and walked to the wall where countless photos of Yn were pinned—some with him, some without. Some from years ago. Some… recent.

“You left her once. I never will.”

A pause.

Then, softly—

“You want proof, Taehyung? I’ll give you proof. But I promise you… by the time I’m done, even your love won’t be enough to save her.”

Meanwhile, in another corner of the city…

A phone rang.

A man picked it up, voice calm.

“Yes, Mr. Jeon?”

Jungkook’s voice was ice.

“Follow Taehyung. Day and night. I want to know where he breathes, who he meets, and how long he plans to live.”

“Yes, sir.”

Jungkook ended the call and stared at the screen again.

Yn sleeping. Peaceful. Unaware.

He smiled—this time soft, warm, as if none of the darkness existed.

“Sleep tight, baby,” he whispered.

“Daddy will take care of everything.”
