That night, Y/N sat at the dining table, quietly stirring her soup, her mother sitting across from her, humming softly as she scrolled through her phone. The atmosphere was peaceful too peaceful.

Then, the front door opened.

Heavy footsteps echoed through the house, commanding, deliberate. Y/N didn’t have to look up to know who it was. She felt him before she saw him.

“Jungkook, you’re home,” her mother said cheerfully, rising from her seat to greet him with a peck on the cheek.

Jeon Jungkook. Her mother’s boyfriend. Her soon-to-be stepfather. And something much, much worse.

Y/N clenched her spoon tighter as he strode into the dining room, his sharp gaze immediately settling on her. There was something unreadable in those dark eyes something dangerous.

“You didn’t wait for me after class.” His voice was smooth, but the underlying authority sent a chill down her spine.

Y/N swallowed hard. “I didn’t think I needed to.”

Jungkook let out a low chuckle, slow and amused, as if she had just told a joke only he understood.

He shrugged off his coat and rolled up his sleeves, revealing inked skin and strong forearms, before taking the seat beside her.

Too close. “I told you I’d pick you up, didn’t I?” he murmured, his tone deceptively gentle.

Her mother, oblivious, smiled. “Oh, Jungkook, you’re so sweet to worry about her. Y/N, you should appreciate him more.”

Y/N forced a tight smile, feeling Jungkook’s stare still burning into her. He was too attentive. Too involved. And the way he looked at her—it wasn’t how a future stepfather should look at his fiancée’s daughter.

It was possessive. “I just want to keep an eye on what’s mine,” he said, lifting his wine glass to his lips.

Y/N stiffened. What’s his? She was about to protest, but his foot brushed against hers under the table, deliberate and firm.

Jungkook smirked over the rim of his glass, dark amusement flickering in his gaze.

She had no idea just how deep she was sinking into his twisted world.

Y/N barely touched her food after that. Every bite felt like it would get stuck in her throat, especially with Jungkook sitting so close, his presence suffocating.

Her mother, as usual, was too wrapped up in her own happiness to notice anything. She gushed about wedding plans, how wonderful Jungkook was, how lucky they were to have him in their lives.

Y/N wanted to scream. Instead, she pushed back her chair. “I’m done. I’ll head upstairs.”

Before her mother could respond, Jungkook’s hand shot out, wrapping around her wrist. Not tightly, not enough to hurt, but enough to remind her—he was in control.

“I’ll see you before bed, sweetheart,” he murmured, his thumb brushing against her pulse point.

Y/N’s stomach twisted. Sweetheart. He only used that word when they were alone. And now, in front of her mother?

She yanked her hand away and hurried upstairs, her heartbeat hammering against her ribs.

Once inside her room, she locked the door, pressing her forehead against it as she took a shaky breath. This wasn’t normal. He wasn’t normal.

A future stepfather shouldn’t act like this. And yet, Jungkook didn’t just act like he was stepping into her mother’s life.

He acted like he was claiming Y/N’s, too.

Later that night…

A soft knock on her door made Y/N freeze. She stayed silent, gripping her blanket.

Maybe he’d go away.

Another knock.

Then click.

The door unlocked. Her breath caught in her throat as Jungkook stepped inside, his expression unreadable in the dim light.

“You locked the door?” he mused, shutting it behind him.

Y/N sat up, gripping the sheets. “You shouldn’t be here.” Jungkook tilted his head, amusement flickering in his dark eyes. “And yet, here I am.”

Her pulse pounded. “If my mom—”

“She’s asleep.” He took slow, measured steps toward her. “I made sure of it.”

Her stomach knotted as he stopped at the edge of her bed, looking down at her. His gaze wasn’t that of a soon-to-be stepfather. It was something far more dangerous.

He reached out, fingers tracing a loose strand of her hair before tucking it behind her ear.

“You’re afraid of me.” His voice was almost gentle. “That’s good. Fear keeps you obedient.”

Y/N’s breath hitched. “What do you want from me?” Jungkook’s lips curled into a slow, dark smile.

“Everything.” Y/N’s hands clenched into fists, her nails digging into her palms as she forced herself to meet his gaze.

“I’m your stepdaughter. Remember that. And you’re my stepfather,” she said, her voice steady despite the fear curling inside her. “So whatever twisted thoughts you have in your head drop them.”

For a moment, silence filled the room. Then Jungkook chuckled, low and slow, as if she had just told the funniest joke.

“Stepdaughter?” He repeated the word like it was foreign, something that held no weight to him. His fingers ghosted along the edge of her blanket, toying with the fabric. “Is that what you think will stop me?”

Y/N swallowed hard. “It should.” His smirk deepened. “It won’t.” A chill ran down her spine.

Jungkook leaned down, caging her in without touching her, his breath warm against her cheek. “Let me make something very clear, Y/N.” His voice dropped, dangerously soft. “The world sees me as your mother’s fiancé. But you and I both know the truth.”

Y/N stiffened, her heart hammering. “What truth?” Jungkook’s fingers brushed her chin, tilting her face up. His dark eyes gleamed with something possessive, something terrifying.

“That you were mine long before she ever was.” Her breath hitched. “You’re insane.” He chuckled again, low and deep. “Maybe.”

Then, just as quickly as he had entered, he pulled away, stepping back toward the door. “Get some sleep, sweetheart.” His smirk was maddening. “You’ll need it.”

And with that, he slipped out of her room, leaving Y/N frozen in place—her mind racing, her skin crawling, and her heart sinking with the terrifying realization:

This wasn’t just an obsession. It was a claim.

-•-

Y/N lay in bed long after Jungkook left, staring at the ceiling, her body rigid with unease. Sleep refused to come, haunted by the weight of his words.

“You were mine long before she ever was.”

Her stomach twisted. How had she caught the eye of someone so dangerous? What had she done to deserve this?

But deep down, she already knew. It wasn’t about what she did. It was about who he was. Jeon Jungkook didn’t fall for people. He claimed them.

And somehow, she had become his latest fixation.

-•-

The next morning, Y/N was out the door before Jungkook could stop her. She didn’t wait for breakfast, didn’t stop to acknowledge her mother’s calls she just left.

The cold air nipped at her skin as she rushed down the street, gripping the straps of her bag as if grounding herself. She needed distance. Space. Air.

But even with miles between them, she still felt him.

His presence lingered like a shadow, creeping into her thoughts, curling around her throat.

She needed to get away.

“Y/N!”

Her body tensed at the sound of her name.

Turning sharply, she saw a familiar face Taehyung.

Her best friend.

Someone safe.

He jogged up to her, his brows furrowed in concern. “What’s wrong? You look like you’ve seen a ghost.”

She let out a shaky breath. “Something worse.” His frown deepened. “Talk to me.”

She wanted to. Desperately. But how did she even begin to explain?

Hey, my soon to be stepfather is obsessed with me and won’t stop looking at me like he owns me.

She shook her head. “I just… need a distraction. Can we go somewhere?”

Taehyung didn’t hesitate. “Of course. Let’s get out of here.” For the first time in days, Y/N felt a shred of relief.

But what she didn’t realize was that even as she ran Jungkook was watching.

And he was not happy.
