The room was dimly lit, the golden glow of the city lights spilling through the floor-to-ceiling windows of Kim Taehyung's penthouse. Outside, the world moved on in its predictable rhythm—cars speeding down the streets, people chasing their small, insignificant dreams. But inside this room, inside this world Taehyung had built around her, nothing existed except his obsession.
She was his.
No matter how much she fought, no matter how much she tried to run, she would always belong to him.
Y/N stood near the window, arms wrapped around herself as if she could hold back the weight of his presence pressing into her soul. She wasn't trembling anymore. She had learned that fear was useless around him. He thrived on it, consumed it like an addiction.
Instead, she stared at her reflection, watching how her dark eyes mirrored the storm inside her. The silk slip she wore was one of the many things he had chosen for her—delicate, expensive, and utterly inescapable. It was a reminder that everything about her was curated by him.
A slow, measured sound of footsteps echoed through the penthouse. She knew without turning that it was him.
Kim Taehyung.
The man who had stolen her freedom. The man who had turned her into an obsession he refused to let go of.
"Are you done pretending to ignore me?"
His voice was deep, smooth like velvet but edged with danger.
Y/N clenched her jaw and exhaled, her fingers curling into the fabric of her slip. "I wasn't ignoring you."
A dark chuckle. "Then what were you doing, sweetheart? Thinking of another escape plan?"
Her heart slammed against her ribs.
She had tried. She had failed.
Again and again.
She had learned that the walls of his world were unbreakable, just like the chains he had wrapped around her.
She turned to face him.
He was dressed in a black button-down, sleeves rolled up to his forearms, the top few buttons undone, exposing a glimpse of his toned chest. He looked every bit the ruthless billionaire the world feared—except they had no idea what lurked beneath his composed facade.
"You said I could have a choice," she said, her voice steadier than she felt.
Taehyung's lips twitched, a hint of amusement dancing in his dark, unreadable eyes. "And you think leaving me is a choice?"
Y/N swallowed, feeling his presence closing in on her like a predator circling its prey.
"That's not love, Taehyung," she whispered.
His expression didn't change, but something in his gaze turned darker, more dangerous.
"Love?" he echoed, stepping closer. "Who said anything about love?"
Her breath caught when he reached for her, his fingers brushing against her cheek before curling under her chin, forcing her to look at him.
"I told you before, Y/N," he murmured, tilting his head slightly. "This isn't about love."
Her pulse thundered.
"This is about you. About what's mine."
She stiffened, but Taehyung only smiled—a slow, devastating thing that sent chills down her spine.
"Love is for the weak," he continued, dragging his thumb across her lower lip, his touch both gentle and possessive. "And I'm not weak, sweetheart. I don't love. I own."
A shiver ran through her.
"You can fight it," he whispered, leaning in until his lips hovered over hers, his breath warm against her skin. "But we both know how this ends."
Y/N hated the way her body reacted, how the space between them felt like a live wire crackling with electricity.
"Tell me, Y/N," Taehyung continued, his voice a hypnotic drawl. "Do you really want to leave me?"
She should have said yes.
She should have pushed him away.
But the truth was a cruel, twisted thing.
She didn't know anymore.
Taehyung exhaled a soft laugh, as if he already knew the answer. His fingers trailed down her throat, lingering over the pulse point that betrayed her.
"You're mine," he said again, his voice laced with finality. "And there's nothing you can do to change that."
Y/N swallowed hard, her chest rising and falling in uneven breaths.
She had been a fool to think she could escape Kim Taehyung.
Because he had never just wanted her love.
He had wanted her soul.
And he wasn't going to let go.
Continuation: Deeper into the Obsession
Her silence stretched between them, fragile yet heavy, a silent surrender she wasn't ready to admit.
Taehyung tilted his head, his eyes burning with satisfaction. "That's what I thought."
He moved past her, unhurried, like a king surveying his empire. His hand casually reached for the crystal decanter on the sleek marble bar, pouring himself a glass of whiskey. He took a slow sip, his eyes never leaving her.
"You keep testing my patience, Y/N," he murmured, swirling the amber liquid in his glass. "And I have very little left."
A surge of defiance flared in her. "Then why keep me here?" she snapped. "Why not just let me go?"
His grip on the glass tightened.
Then, in one swift motion, he slammed it onto the counter. The sharp sound of shattering glass echoed through the penthouse.
Y/N flinched.
The tension crackled like a storm, thick and suffocating.
Taehyung exhaled through his nose, his jaw ticking as he fought for control. When he finally looked at her, his expression was unreadable—but his eyes, they were ruthless.
"You still don't get it," he said, voice eerily calm. "I don't let go of what's mine."
He moved toward her with slow, deliberate steps, each one making her heart hammer against her ribs.
"Every time you think about running," he whispered, stopping just inches away, "I want you to remember something."
He lifted his hand, his fingers grazing the side of her neck before settling over her pulse.
"I found you once," he murmured. "And I'll always find you again."
Y/N shivered.
His touch, his voice, his very presence wrapped around her like a noose.
"You think I don't know the way your mind works?" Taehyung mused, his fingers trailing down her arm, igniting a fire in their wake. "Every time you look at the door, you calculate how far you can get before I catch you."
She swallowed hard, unwilling to confirm his words.
He leaned in, his lips brushing against the shell of her ear. "And yet, you never run."
His words sent a shiver down her spine.
"You want to run," he whispered, "but something keeps you here."
Y/N squeezed her eyes shut. "You're wrong."
"Am I?"
His fingers curled under her chin again, tilting her face up.
"Then tell me, sweetheart," he murmured, voice silk and steel. "Why are you still here?"
Her breath hitched.
His gaze dropped to her lips.
And then he kissed her.
It wasn't soft. It wasn't gentle.
It was possession.
Raw, unrelenting, and demanding.
His hands slid to her waist, pulling her against him, molding her body to his. Y/N gasped, her fingers instinctively gripping the fabric of his shirt.
Every kiss, every touch, was a claim—a silent declaration that she belonged to him.
When he pulled back, his forehead rested against hers, his breath heavy, his grip firm.
"Run all you want," he murmured against her lips. "But you'll always find your way back to me."
A war raged inside her.
She wanted to fight. She wanted to escape.
But Kim Taehyung was a man who didn't just take control.
He became it.
And no matter how much she resisted…
She was already his.
