Psycho in Your Love Y/N is a simple, soft-hearted girl who lives a quiet life. jungkook is a mafia.rude,cold,mad in love with yn
The rain poured heavily against the city streets, drowning the faint hum of life beneath its merciless downpour. Inside a cozy bookstore, Y/N stood behind the counter, flipping through the pages of a novel with a small smile. She loved nights like these quiet, peaceful, and far away from the chaos of the outside world.
Y/N glance up instinctively. Her breath hitched. A man entered, his presence overwhelming the tiny shop instantly. Drenched in the rain, he shook his dark hair slightly before his sharp gaze locked onto hers. His eyes—cold, dark, and utterly lifeless sent a shiver down her spine.
Jeon Jungkook.
The name alone was enough to make people tremble. The mafia king. The devil in a suit. A man whose mere presence was a warning—stay away, or be destroyed.
Y/N had only seen him on the news or whispered about in hushed tones. But now, he stood right in front of her, radiating danger and something else—something that made her heart pound against her ribs in both fear and… curiosity.
“Close the shop,” he ordered, his deep voice slicing through the silence like a blade.
Y/N blinked. “W-What?”
He took slow, deliberate steps toward her, the sound of his boots echoing off the wooden floor. “I don’t like repeating myself, sweetheart.”
Sweetheart? The way the word rolled off his tongue sent a strange warmth through her, but she forced herself to stay focused. “I… I can’t just close the shop. It’s still open hours.”
A smirk ghosted his lips. Amusement. Something dangerous flickered in his gaze. “You’re brave.”
Y/N swallowed hard. She wasn’t brave—just confused. Why was Jeon Jungkook here? What did he want from her?
Before she could question further, the door opened again, and a group of men entered, their suits soaked from the rain. The air shifted—heavy with tension.
One of them, a tall man with a scar along his jaw, sneered. “You’re making this difficult, Jungkook.”
Jungkook turned slightly, his body shielding Y/N from their view. “And you’re making a mistake standing here, breathing.”
The man laughed, but it held no humor. “We both know you don’t make threats. You make examples.”
Jungkook sighed as if this was nothing more than an inconvenience. Then, without warning, he pulled out a gun and fired.
A scream caught in Y/N’s throat as the man with the scar collapsed, blood pooling beneath him. The others reached for their weapons, but before they could even aim, Jungkook moved like a shadow swift, merciless. One shot. Two. Three.
Silence.
Y/N’s body trembled. Her entire world had just shifted.
Jungkook turned back to her, his expression unreadable. He stepped closer, until she was trapped between him and the counter. “You should be scared of me.”
She was. Terrified. But there was something else in his gaze now, something darker. His fingers reached out, tucking a strand of hair behind her ear, his touch freezing against her burning skin.
“I don’t know why,” he murmured, eyes never leaving hers, “but I don’t want you to be.”
Y/N’s heart slammed against her ribs.
What had she just gotten herself into?
Y/N’s fingers trembled as she locked the bookstore’s door behind her. Her heart pounded so loudly in her chest that she could barely hear the rain drizzling onto the pavement. The street was eerily silent now, but the gruesome images from minutes ago still played in her mind.
Blood. Death.
And him.
Jeon Jungkook stood a few feet away, his sharp eyes fixated on her as if she were prey caught in his web. He had just killed three men—without hesitation, without emotion. There wasn’t a single trace of remorse in his expression. Instead, something darker lingered in his gaze. Something possessive.
Y/N swallowed hard and took a shaky step back. “I… I should go home.”
Jungkook tilted his head slightly, his lips curling into an almost amused smirk. “Home?” he repeated, voice deceptively soft. “And you think I’ll just let you walk away after what you saw tonight?”
Fear spiked through her veins like ice.
She had witnessed a brutal mafia execution. Of course, he wouldn’t just let her leave.
“Please,” she whispered, her voice barely audible. “I swear, I won’t tell anyone. I didn’t see anything.”
Jungkook let out a low chuckle, taking a slow step toward her. “Sweetheart,” he murmured, his fingers gently tilting her chin upward. His touch was light, but the weight of his presence was suffocating. “If I thought you were a threat, you’d already be lying in a pool of blood like them.”
Y/N’s breath hitched. His words sent a shiver down her spine.
He wasn’t lying.
He could kill her right now, and no one would even know.
And yet… he hadn’t.
Her heart pounded as he studied her face. His gaze flickered to her trembling lips before he let her go, stepping back just slightly. “But I don’t like loose ends,” he said, voice lower now. “And you… you’re interesting.”
Y/N didn’t want to be interesting to him.
She just wanted to disappear.
“I just want to go home,” she tried again, her voice shaky.
Jungkook sighed, as if considering something. Then, to her surprise, he took a step back. “Fine.”
Y/N blinked in disbelief. “R-Really?”
A slow, dangerous smirk crossed his lips. “Did you expect me to kidnap you?”
He chuckled. “Not tonight.”
Relief barely had time to settle in before his next words sent a chill down her spine.
“I’ll come find you soon, Y/N.”
Her breath caught.
He knew her name.
She hadn’t told him, yet he knew.
As Jungkook disappeared into the darkness, Y/N realized one thing—she hadn’t just witnessed a crime.
She had caught the attention of the devil himself.
And now, there was no escape.
The air outside felt suffocating as Y/N hurried down the empty street. The rain had slowed to a drizzle, Her mind was too clouded, heart still racing from what had just happened.
Jungkook’s voice echoed in her head.
"I’ll come find you soon, Y/N."
Her fingers clenched into fists as she walked faster. He knew her name. He knew who she was.
How?
She had never met him before tonight, wasn’t someone who got involved with criminals. She was just a simple girl, working in a bookstore, living a quiet life.
Then why did the most dangerous man in the city suddenly take an interest in her?
Her apartment was just a few blocks away, but every step she took felt heavier, her paranoia growing. She glanced over her shoulder more than once, convinced she was being followed. The streets were empty, but she didn’t feel alone.
Her instincts screamed at her to run.
Finally, she reached her building. With shaky hands, she unlocked the door and hurried inside, locking it behind her. She pressed her back against the cold wood, sucking in deep breaths, trying to calm the storm in her chest.
It’s over.
At least for tonight.
She forced herself to move, stripping off her damp coat and tossing it onto the chair. Her apartment was small, cozy—books stacked on shelves, fairy lights twinkling softly against the windows. It was her safe space.
Tonight, it didn’t feel safe at all.
She moved toward the window, hesitating before peeking through the curtain. The street below was quiet. No sign of anyone. No sign of… him.
She let out a shaky breath. Maybe he wasn’t serious. Maybe he had just been trying to scare her.
Maybe she could pretend this night never happened.
But pretending was impossible when the nightmares came.
She jolted awake sometime past midnight, drenched in sweat, the images of gunshots and lifeless bodies flashing behind her eyes. Jungkook’s cold gaze haunted her, the memory of his fingers brushing her skin making her shiver even now.
She sat up, pressing her palm against her chest, willing her heart to slow down. It’s just a dream.
That’s what she told herself.
But then—
Her phone buzzed.
A single message.
"Sweet dreams, sweetheart."
Her blood ran cold.
Her hands shook as she stared at the message, her mind racing. No name, no number—just those words.
Sweet dreams.
Her breath came in shallow gasps as realization sank in.
He had found her.
Jungkook knew where she lived.
Y/N’s fingers tightened around her phone as she stared at the message glowing on the screen.
"Sweet dreams, sweetheart."
Her breath hitched. Her skin grew cold.
This wasn’t a coincidence.
This wasn’t some sick prank.
Jungkook had found her.
A tremor ran through her as she slowly placed her phone down on the nightstand, her heart pounding against her ribcage. Her hands were shaking, and no matter how many times she tried to calm herself, her body refused to stop trembling.
A new kind of fear settled inside her—a fear she had never experienced before. It wasn’t just about witnessing a crime anymore. It wasn’t just about being in the wrong place at the wrong time.
Jungkook had chosen her.
And now, there was no escaping him.
She rushed back to her nightstand, grabbing her phone with shaky fingers. She had to call someone—anyone. But as soon as she unlocked her screen, she froze.
it wasn’t a message.
It was a call.
From an unknown number.
Her heart slammed against her chest as she stared at the screen, the ringing filling the silence of her apartment. She didn’t want to answer. Every instinct screamed at her not to.
But she knew.
She knew it was him.
And ignoring him wasn’t an option.
With a shaky breath, she slid her thumb across the screen and lifted the phone to her ear.
“H-Hello?” Her voice came out small, weak.
A low chuckle came from the other end. Slow. Amused.
“Why do you sound so scared, sweetheart?”
Y/N’s blood ran cold.
Jungkook.
His voice was smooth, dark, and laced with something that made her stomach twist uncomfortably.
She swallowed hard, gripping the phone tightly. “What do you want from me?”
There was a brief silence, then—
“I haven’t decided yet.”
His answer made her breath hitch.
“I let you go once,” he continued, his voice softer now, almost gentle. “But that doesn’t mean I forgot about you.”
Y/N closed her eyes, forcing back the panic rising in her throat. “Please,” she whispered. “I just want to forget what happened. I won’t tell anyone—I swear.”
Jungkook let out a small hum, as if considering her words. Then, he chuckled.
“You think this is about what you saw?”
She froze.
Wasn’t it?
“You’re wrong, sweetheart.” His voice dipped lower, sending a shiver down her spine. “This isn’t about what you saw. This is about you.”
Her breath caught. “M-Me?”
“Yes.”
Her grip on the phone tightened. She didn’t understand. Why her?
“I don’t like loose ends,” he said again. “But that’s not the only reason I’m here.”
A strange silence filled the space between them before he spoke again—his next words sending a sharp chill through her veins.
“I think I like you, Y/N.”
Her body stiffened. Her pulse pounded.
Like her?
She didn’t know what terrified her more—the fact that he had found her so easily or the possessiveness laced in his voice.
“You belong to me now.”
She gasped.
Jungkook chuckled at her reaction, but his next words were serious.
“If I ever see another man near you, I won’t be so kind next time.”
Y/N’s breathing grew shallow.
She knew what he meant.
He wouldn’t hesitate to kill.
Tears pricked her eyes as reality sank in. There was no escaping this. No escaping him.
Jungkook had made up his mind.
And she was his.
Y/N’s grip on the phone weakened, her fingers trembling as Jungkook’s words echoed in her head.
“You belong to me now.”
Her breath came in shallow, uneven gasps, her chest tightening with fear. She wanted to scream, to deny his claim, but deep down, she knew the truth. Jungkook wasn’t the kind of man who made empty threats.
This was real.
She was trapped.
“W-Why?” she finally whispered, her voice barely audible.
Jungkook chuckled, the sound dark and laced with amusement. “Why?” he repeated, as if tasting the word. “Because I want you, sweetheart.”
His tone sent a violent shiver down her spine.
“But I—” She swallowed hard, struggling to find her voice. “I don’t belong to you.”
Silence.
Then, a low, dangerous hum. “Oh, Y/N… You don’t understand yet, do you?” His voice turned sharper, colder. “I always get what I want.”
Tears burned at the corners of her eyes. Her body was paralyzed, mind racing for a way out.
But there was no way out.
Not from him.
“I’ll see you soon,” Jungkook murmured, his voice softer now, but no less terrifying. “And don’t even think about running.”
The line went dead.
Y/N let out a shaky breath, her hands gripping the phone so tightly that her knuckles turned white.
She wanted to believe this was just a nightmare, that she would wake up and none of it would be real.
But the cold, hard reality was staring right at her.
Jungkook had found her.
And now, he wouldn’t let her go.
The next morning, Y/N barely got any sleep. Her eyes burned from exhaustion, but she forced herself out of bed, determined to go about her life as normally as possible.
She would not let him control her.
She wouldn’t let fear consume her.
Her bookstore was her only escape—the only place where she felt safe. As she unlocked the shop and stepped inside, the familiar scent of paper and ink wrapped around her like a comforting embrace.
For a moment, she allowed herself to breathe.
But peace never lasted long.
Because as soon as she turned on the lights, her heart stopped.
There, sitting casually on a chair in the middle of the store, was Jungkook.
Dressed in all black, his sharp eyes locked onto hers the moment she stepped inside. A slow, knowing smirk curled on his lips, as if he had been waiting for this exact moment.
Y/N’s breath hitched. She took an instinctive step back, her body screaming at her to run—but the door behind her clicked shut on its own.
Her stomach dropped.
Jungkook’s men.
She hadn’t even noticed them before, but now, as she glanced to the side, she saw two unfamiliar figures standing near the entrance, their expressions blank, cold.
A trap.
Her heart pounded wildly, panic clawing up her throat.
“What—” she started, but her voice failed her. “What are you doing here?”
Jungkook tilted his head slightly, his gaze never leaving hers. “Didn’t I tell you, sweetheart?” His smirk widened, his voice dripping with amusement. “I told you I’d see you soon.”
Y/N felt her hands tremble at her sides. She had spent the entire night convincing herself that he was just trying to scare her.
But now, standing in front of him, she realized the truth.
Jungkook wasn’t just dangerous.
He was obsessed.
She forced herself to stay calm, despite the terror bubbling inside her. “You have no right to be here,” she said, her voice stronger than she expected. “This is my store.”
Jungkook chuckled, leaning back against the chair like he owned the place. “Your store?” He tapped his fingers against the wooden surface of the table beside him. “I could burn this place down in seconds, sweetheart.”
Her breath caught.
“But I won’t,” he continued smoothly, standing up slowly. “Because I like you.”
He took a step forward, and instinctively, Y/N stepped back—only to bump into one of his men.
She was trapped.
Jungkook’s smirk deepened at her reaction. “I came to warn you,” he murmured, his voice dark, lethal. “Stay away from other men.”
Her hands clenched into fists. “You don’t control me.”
He hummed, seemingly amused by her defiance. “No?” His gaze darkened, his playful smirk vanishing. “Then tell me, sweetheart. If I don’t control you, why are you shaking?”
Her breath hitched.
Before she could respond, Jungkook closed the distance between them in an instant.
One hand grabbed her wrist, the other tilting her chin up, forcing her to meet his gaze. His touch wasn’t rough, but it wasn’t gentle either.
It was possessive.
Y/N’s pulse thundered.
“You’re mine,” he whispered, his voice dropping to a dangerous level. “And the sooner you accept that, the easier it’ll be for you.”
Tears pricked her eyes, but she refused to let them fall.
She refused to break.
Jungkook studied her face for a long moment before exhaling sharply. “You’re scared of me.”
It wasn’t a question. It was a statement.
But before Y/N could deny it, his lips curled into a smirk again.
"Good."
He let go of her suddenly, stepping back. The shift in his mood was so quick that it left her dizzy.
Jungkook turned toward the door, his men immediately stepping aside to let him pass. Before leaving, he glanced back at her one last time.
"I’ll come back for you, Y/N. Don’t test my patience."
And then, just like that, he was gone.
Leaving Y/N standing there—shaken, terrified, and fully aware.
She would never be free of him.
Y/N stood frozen in the middle of her bookstore, her heart slamming against her chest as Jungkook’s last words echoed in her head.
“I’ll come back for you, Y/N. Don’t test my patience.”
Her fingers curled into fists as she fought the tremor in her body. The air around her still felt heavy, like his presence lingered even after he had left.
She needed to get out.
She needed to escape before it was too late.
Rushing to the front of the store, she locked the door, her hands trembling. The silence that followed was suffocating, as if the walls were closing in on her.
She had to think.
Jungkook wasn’t going to leave her alone. He had made that clear. But why? Why had he chosen her? What was it about her that made a man like him so obsessive?
Her stomach twisted.
There was no point in questioning it. He had decided she was his, and now, no amount of logic or reasoning would make him change his mind.
She had to leave the city.
The thought struck her like a bolt of lightning. If she disappeared, if she ran far away, maybe—just maybe—she could escape his grasp.
But even as the idea formed in her head, doubt crept in.
Would he let her go that easily?
No.
A man like Jungkook didn’t allow things to slip from his hands.
She was in his world now.
And there was no escaping him.
Nightfall
Y/N spent the rest of the day in a daze, jumping at every sound, flinching whenever the bell above her door chimed. Every customer that entered sent her pulse racing, fearing it would be him again.
By the time she closed the shop, exhaustion weighed heavily on her shoulders. But the real fear settled in when she stepped outside.
Was he watching?
She could feel it.
A presence.
A shadow lurking nearby.
Swallowing her fear, she forced herself to walk, keeping her head down. Her apartment wasn’t far, but every step felt like an eternity.
As she turned the corner onto her street, her heart nearly stopped.
A black car was parked near her building.
Sleek. Expensive. Tinted windows.
Jungkook’s.
Panic surged through her. She turned around, ready to run—but a strong hand grabbed her wrist.
A gasp tore from her lips as she spun around, her eyes widening in terror.
Jungkook.
He stood there, dressed in all black, his grip firm but not painful. His expression was unreadable, but his dark eyes burned into hers, devouring her every move.
“You’re avoiding me.”
It wasn’t a question. It was a statement. A dangerous one.
Y/N swallowed, trying to wrench her hand away. “Let me go.”
He didn’t.
Instead, he tilted his head slightly, studying her reaction. “Where were you going just now?”
She hesitated. “Home.”
Jungkook let out a hum of amusement. “Liar.”
Her pulse quickened.
He knew.
He always knew.
She tried again to pull away, but this time, his grip tightened. Not enough to hurt, but enough to remind her who was in control.
“I don’t like when people lie to me, Y/N.”
His voice was smooth, but there was an edge to it—a warning.
“I wasn’t lying,” she whispered, her throat dry.
Jungkook exhaled slowly, his thumb brushing against the inside of her wrist. “You were thinking about running, weren’t you?”
Y/N’s breath hitched.
How did he—
She didn’t need to ask. He knew everything.
A slow smirk tugged at his lips. “You think I wouldn’t find you?” His voice dropped lower, sending shivers down her spine. “Sweetheart, there’s nowhere in this world you can run where I won’t follow.”
Her stomach dropped.
“I don’t belong to you,” she whispered, her voice barely audible.
Jungkook’s smirk faded.
Something dark flickered in his eyes—something dangerous.
Without warning, he yanked her closer, their bodies almost touching.
Y/N gasped, her hands instinctively landing on his chest. She could feel the heat of his body, the steady, powerful beat of his heart.
“You don’t get to decide that,” Jungkook murmured, his breath ghosting over her lips.
Her entire body tensed.
“You belong to me, Y/N,” he continued, his grip possessive, unyielding. “And I will never let you go.”
A chill ran down her spine.
His obsession wasn’t just dangerous—it was deadly.
She had stepped into his world.
And now, she would never be free.
Y/N’s breath came in short, panicked gasps as Jungkook carried her effortlessly down the stairs of her apartment building. His grip was unbreakable, his arms like steel around her body. She kicked and struggled, but he didn’t even seem bothered by it.
“Jungkook! Let me go!” she screamed, pounding her fists against his chest.
He didn’t respond.
The moment they reached the exit, the cold night air hit her, but it did nothing to calm the fire of terror burning inside her. A sleek black car was parked in front of the building, its engine humming softly.
A man in a suit—one of Jungkook’s guards—opened the door.
“No—no, no, please—” Y/N tried to wriggle out of Jungkook’s grip, her voice breaking in desperation.
Jungkook didn’t even glance at her. Without hesitation, he placed her inside the car, shutting the door before she could try to escape.
She lunged for the handle, but—locked.
Her breathing turned frantic. “Jungkook, you can’t do this! You can’t just take me!”
Jungkook slid into the seat beside her, his dark gaze cold and unreadable. “I just did.”
The car started moving.
Y/N’s hands shook as she pounded on the window, but it was no use. The glass was thick, reinforced. She was trapped.
She turned back to him, anger and fear clashing inside her. “Where are you taking me?”
Jungkook leaned back, resting his arm on the seat, watching her with an expression of amusement. “Home.”
Her stomach twisted. “Home?” she echoed.
“My home,” he clarified, his voice smooth, calculated.
Y/N’s blood ran cold.
“No,” she shook her head, her pulse skyrocketing. “No, you can’t do this! This is kidnapping!”
Jungkook let out a dark chuckle. “Call it whatever you want, sweetheart.”
Her hands clenched into fists. “Lisa—your wife—what about her?”
Something dark flickered in his eyes at the mention of Lisa. His jaw tightened slightly, but he quickly masked it with a smirk. “That’s none of your concern.”
Y/N’s nails dug into her palms. “You’re insane,” she whispered.
Jungkook tilted his head, his smirk deepening. “And you’re finally understanding that.”
Tears burned at the back of her eyes, but she refused to let them fall. She refused to let him see her break.
The car ride was long, silent except for the soft hum of the engine. Y/N’s mind raced, searching for a way out, but every second that passed made her realize—there was no escape.
The Mansion
By the time they arrived, Y/N’s heart was pounding so hard she could barely breathe.
The gates to Jungkook’s mansion were massive, lined with security cameras and guards dressed in black. The moment the car rolled inside, she knew—she was in his world now.
The mansion itself was grand, intimidating, and surrounded by darkness. The air felt suffocating.
As soon as the car stopped, Jungkook opened the door and stepped out before turning back to her. “Come.”
Y/N didn’t move.
His smirk faded, his eyes darkening. “Don’t make me drag you inside.”
Her body trembled. She knew he would do it.
Taking a shaky breath, she stepped out, her legs feeling weak beneath her. The moment she did, Jungkook’s hand wrapped around her wrist, pulling her toward the entrance.
The guards at the door didn’t even blink as they stepped aside, letting them pass.
Y/N’s chest tightened. They knew.
They knew their boss had just dragged in an unwilling girl, and they did nothing—because no one disobeyed Jeon Jungkook.
Inside the Beast’s Den
The inside of the mansion was breathtaking yet suffocating. The halls were lined with expensive paintings, chandeliers hanging from the ceiling, the floors polished to perfection.
But none of that mattered to Y/N.
Because no matter how beautiful this place was, to her—it was a prison.
Jungkook led her through the hallways, his grip firm but not painful. It was as if he was making a point—he wasn’t hurting her, but she wasn’t allowed to leave either.
They stopped in front of a large wooden door. Jungkook pushed it open and led her inside.
Y/N’s breath caught.
The room was massive, decorated in deep shades of black and gray. A king-sized bed sat in the center, the windows covered with thick curtains.
“This is your room,” Jungkook said.
She turned to him, eyes wide. “You’re keeping me here?”
Jungkook smirked, stepping closer until their bodies were almost touching. “Where else would you go?”
Her breath hitched. “Jungkook… please,” she whispered, desperation creeping into her voice. “You don’t have to do this.”
For a moment, something flickered in his gaze—something raw, something almost vulnerable.
But then, just as quickly, it was gone.
He leaned down, his breath ghosting over her ear. “Go to sleep, sweetheart,” he murmured. “You’re not leaving.”
With that, he turned and walked out, locking the door behind him.
Y/N ran to the door, twisting the handle frantically. Locked.
Her body slid down against the door, tears finally escaping her eyes.
She was trapped.
And she had no idea if she would ever be free again.
Y/N sat against the cold door, her arms wrapped around her knees as silent tears streamed down her face. Her heart pounded so loudly that she could hear it echo in the silence of the massive bedroom.
She had tried everything—banging on the door, screaming for help, searching for another way out. But the windows were locked, reinforced, and the door wouldn’t budge.
She was trapped.
She wiped her tears away angrily. Crying wouldn’t solve anything. She had to stay strong. There had to be a way out of here.
Standing up, she scanned the room again. The bed was luxurious, the furniture expensive, but none of it mattered to her. This wasn’t a bedroom—it was a prison.
Suddenly, a knock on the door made her jump. Before she could react, the door unlocked, and a woman dressed in black stepped in.
“You should freshen up,” she said politely, though there was no warmth in her voice. “Dinner will be served soon.”
Y/N stared at her. Dinner?
Did Jungkook seriously expect her to act normal?
“I don’t want to eat,” Y/N said firmly.
The woman didn’t react. “Master Jungkook insists.”
Y/N’s stomach twisted. She clenched her fists. She didn’t want to do anything he wanted.
But she needed strength. If she was going to find a way out of here, she needed to stay healthy.
After a long pause, she finally nodded. “Fine.”
The woman gave a small bow before leaving the room.
Y/N exhaled shakily. This wasn’t over.
