Kim {user} was born on a Tuesday.
Not that anyone in her family would remember the day of the week. What they remembered was the moment the nurse placed her in her mother's arms, the way her father—a man who commanded rooms full of powerful people without breaking a sweat—had wept openly, the way her grandparents had driven three hours through traffic just to see her tiny fingers curl around their thumbs.
She was, from the very first breath she took, the center of their universe.
The Kim family was not just wealthy. They were the kind of wealthy that made other wealthy people uncomfortable. Her father was a politician, one of those men whose name appeared in headlines and whose decisions shaped policies. Their home was not a house but an estate, a sprawling property in the most exclusive neighborhood of Seoul, with gates that recognized the cars of approved visitors and gardens that required a team of six to maintain.
Her mother had been a socialite before marriage, a woman of impeccable taste and quiet ambition. She had wanted more children—a sibling for {user}, a playmate, someone to share the burden of being a Kim. But her body had refused. Three miscarriages, each one more devastating than the last, until the doctors finally told her what she already knew in her heart: one child was all she would ever have.
So they poured everything into {user}.
Not in a way that was cruel or neglectful. They didn't buy her affection or substitute material things for presence. They simply... gave her what she wanted. Always. Every toy she pointed at, every dress she admired, every whim that crossed her mind—it was hers. Not because they were trying to spoil her, but because they couldn't bear to see her unhappy. Not even for a moment.
Her grandparents were worse.
Her father's mother, a woman who had survived war and poverty and built an empire from nothing, melted into a puddle of affection whenever {user} walked into the room. She would spend hours braiding {user}'s hair, telling her stories of the old days, pressing expensive jewelry into her small hands and telling her that one day, all of this would be hers.
Her mother's father, a retired judge with a reputation for being cold and unyielding in the courtroom, became a different person entirely when his granddaughter climbed onto his lap. He would read to her for hours, his stern voice softening as he did the voices of the characters, making her laugh until she couldn't breathe.
She was loved. Truly, deeply, unconditionally loved.
And because of that love, because of the way the world had always bent to accommodate her, {user} grew up believing that it always would.

The Seoul International Academy was not a school.
It was a kingdom.
Hidden behind gates that required three levels of security clearance, nestled in a neighborhood where the streets were clean enough to eat off and the air seemed to shimmer with privilege, the Academy was where the children of Korea's elite were molded into the next generation of power.
The sons and daughters of politicians walked its hallowed halls. The heirs to business empires sat in its classrooms, their designer backpacks slung over shoulders that would one day carry the weight of entire companies. The children of actors and idols and famous athletes—the ones who had transcended mere celebrity to become institutions—mingled in its courtyards.
No one at the Academy was poor. No one at the Academy was ordinary. No one at the Academy was anything less than exceptional.
And {user} was the most exceptional of them all.
Not because of her grades—though she was smart enough when she bothered to apply herself. Not because of her athletic abilities—though she was graceful and quick when she wanted to be. She was exceptional because she was Kim {user}, and being Kim {user} meant something.
It meant that when she walked into a room, people noticed. It meant that when she spoke, people listened. It meant that when she wanted something, people found ways to give it to her.
The Academy was divided into three phases, like the chapters of a book that had been written long before any of them were born. Kindergarten, where the youngest children of the elite learned their letters and their places in the hierarchy. Middle school, where friendships were formed and alliances were tested. And high school, where the real games began.
{user} had moved through each phase like a queen surveying her kingdom.
In kindergarten, she had been the darling—the pretty little girl with the bright smile and the expensive clothes who made everyone want to be her friend. In middle school, she had been the leader—the one who decided who was in and who was out, whose approval was sought and whose displeasure was feared.
But in high school, something changed.
In high school, {user} learned that not everyone would bend.
---
It started with small things.
A girl in her class refused to give up her seat in the library. A boy disagreed with her opinion during a debate. A teacher gave her a grade she felt she didn't deserve.
Small things. Insignificant things. Things that shouldn't have mattered.
But to {user}, who had never been told no, who had never been denied anything she truly wanted, these small things felt like declarations of war.
And {user} did not lose wars.
The first fight was verbal—a sharp exchange of words that left the other girl in tears. The second was physical—a shove in the hallway that sent a boy stumbling into a locker. The third was worse—a confrontation that ended with a bloody nose and a trip to the principal's office.
Her parents were called. Meetings were held. Promises were made.
But nothing changed.
Because {user} was a Kim. And Kims didn't face consequences. They faced solutions. The other students were quietly transferred. The teachers were reminded of who her father was. The principal, a man who understood the way the world worked, made sure the incident was buried.
And {user} learned a lesson that would shape the rest of her life.
She could do anything.

Noah entered the Academy in the second semester of {user}'s first year.
His arrival was not announced. There was no fanfare, no special assembly to introduce the new student. He simply appeared one morning, walking through the gates like he had always belonged there, and the Academy shifted on its axis.
He was beautiful.
Not in the way that the other boys were beautiful—polished and practiced, their good looks honed by stylists and personal trainers. Noah was beautiful in a way that felt natural, almost accidental. His father was Korean, a businessman who had built an empire in shipping. His mother was German, a model who had graced the covers of magazines before retiring to raise her son.
The combination was devastating.
Dark hair that fell across his forehead in a way that made girls want to push it back. Blue eyes that seemed to see right through people. A lean physique that moved with the kind of grace that came from years of athletic training. And a smile—God, that smile—that could make even the most composed girl forget her own name.
He was also brilliant.
His grades were impeccable, his essays were praised, his contributions in class were always thoughtful and well-reasoned. He excelled in every subject, from mathematics to literature, from science to history.
But it was in sports that he truly shone.
The Academy was famous for its athletic program—not just for the quality of its teams, but for the way those teams had produced some of the finest athletes in the country. Olympic medalists, professional players, coaches who had gone on to shape the next generation.
The program was divided into two teams: the Hawks, whose colors were red, and the Wolves, whose colors were blue. Twenty-two players in total, eleven on each team. Two coaches, each one determined to prove that their approach was superior.
The rivalry between the Hawks and the Wolves was legendary.
It wasn't just about sports. It was about pride, about legacy, about which team would be remembered when the final whistle blew. The students chose sides, wearing red or blue, arguing over which team was superior, attending matches with the kind of fervor usually reserved for religious ceremonies.
When Noah tried out for the Hawks, no one was surprised.
He was fast—faster than anyone else on the field. He was agile, his movements fluid and precise. He had an instinct for the game that couldn't be taught, a sense of where the ball would be before anyone else knew it.
The coach watched him for ten minutes and made a decision.
Noah would be the captain.
---
Jungkook had been the captain of the Wolves long before Noah arrived.
He was, by any measure, the best player the Academy had ever seen. His skills were almost supernatural—the way he moved, the way he anticipated, the way he made the impossible look effortless. He had led the Wolves to victory after victory, his name spoken with reverence by coaches and players alike.
He was also, unlike Noah, born into a family that made the Kims look almost modest.
The Jeons were not just rich. They were the richest. Their name was synonymous with power, with influence, with the kind of wealth that had been accumulating for generations. Jungkook's father was a titan of industry, a man whose business dealings spanned continents and whose word could make or break governments.
And he had raised his son to be the same.
Jungkook had been competing since he could walk.
Competing in academics, where he consistently ranked at the top of his class. Competing in sports, where he dominated every game he played. Competing in life, where every interaction was a battle to be won.
But there was one competition that mattered more than all the others.
The competition with Noah.
Their fathers had been rivals before they were born—business rivals whose hatred for each other was legendary. They had fought over contracts, over territory, over the kind of power that only money could buy. Their feud had spilled over into every aspect of their lives, until it became impossible to separate business from personal.
And their sons had inherited that feud like a birthright.
Jungkook and Noah had known each other since childhood. They had attended the same exclusive preschools, the same private tutors, the same elite events where the children of the powerful were paraded before each other like prize animals.
They had hated each other from the very beginning.
It was a hatred that was almost instinctual—a primal recognition that the other was a threat. They competed over everything: grades, sports, attention, girls. They traded victories and defeats like blows in a boxing match, each one landing harder than the last.
And then Noah had taken {user}.
---
Jungkook had noticed {user} long before she noticed him.
How could he not? She was the most beautiful girl in the Academy, the daughter of the most powerful politician in Seoul, the untouchable princess who walked through the halls like she owned them.
He had watched her from afar—the way she laughed, the way she moved, the way she commanded attention without even trying. He had admired her from a distance, telling himself that he would approach her when the time was right.
But the time had never been right.
Because before he could make his move, Noah had made his.
---
{user} had never been in love before.
She had liked boys. She had flirted with boys. She had even kissed a boy once, at a party in her first year of middle school, a forgettable experience that had left her feeling nothing but curiosity about what the fuss was all about.
But she had never been in love.
Not until Noah.
She noticed him the moment he walked through the gates. Everyone did. He was impossible to miss, with his dark hair and his blue eyes and the way he carried himself like he had nothing to prove.
But it was more than his looks. It was the way he smiled at the teachers, polite and respectful. It was the way he helped a younger student who had dropped her books, crouching down to gather them without a second thought. It was the way he laughed—genuinely, openly, like he didn't care who was watching.
{user} found herself staring.
She stopped herself, of course. She was a Kim. Kims didn't stare. Kims were stared at.
But she couldn't help it.
The weeks passed and the staring continued. She found reasons to walk past the fields during practice, watching as Noah ran drills with the other players. She found excuses to linger in the hallways near his locker, hoping for a glimpse of him between classes.
She was falling. Hard.
And she hated it.
Because {user} was not the kind of girl who fell. She was the kind of girl who was fallen for. She was the kind of girl who received confessions, not gave them. She was the kind of girl who chose, not the kind of girl who was chosen.
But Noah made her want to be chosen.
So one day, after months of watching and waiting, she made a decision.
She would confess.
---
The auditorium was empty when she found him.
He was sitting on the stage, his legs dangling over the edge, reading a book. The afternoon light streamed through the windows, casting shadows across his face.
He looked up when she approached. His blue eyes met hers, and for a moment, she forgot how to breathe.
"{user}," he said, surprised. "What are you doing here?"
She didn't answer immediately. She was too busy trying to remember the speech she had prepared, the words she had practiced in front of the mirror a hundred times.
"I like you," she said.
The words came out louder than she intended, echoing in the empty auditorium. She winced, feeling heat rush to her cheeks.
Noah stared at her.
"I like you," she repeated, quieter this time. "I've liked you since you arrived. I know I'm not supposed to—I know it's not the way things are supposed to work—but I can't help it. I can't stop thinking about you. I can't stop watching you. And I can't pretend anymore."
The silence stretched between them, endless and terrifying.
And then Noah smiled.
He set his book aside and stood, walking toward her slowly, deliberately. When he reached her, he stopped, close enough that she could smell his cologne, close enough that she could see the flecks of green in his blue eyes.
"I was wondering when you'd say something," he said.
"What?"
"I've been watching you too, {user}. I just didn't think the princess of Seoul would ever look at someone like me."
She blinked. "Someone like you?"
"Someone ordinary."
She laughed at that—a bright, surprised sound that broke the tension. "There's nothing ordinary about you."
He smiled again, that devastating smile that made her knees weak.
"So," he said, "does this mean I can kiss you now?"
And {user}, who had never been at a loss for words in her life, could only nod.
---
They became a couple the next day.
The Academy buzzed with the news, whispers following {user} wherever she went. Noah Kim and {user} Kim—the two most beautiful people in the school, the prince and princess, the golden couple who seemed destined for each other.
Some were happy for them. Others were jealous. And some, a small but vocal minority, were furious.
The girls who had admired Noah from afar, who had dreamed of catching his attention, found their dreams shattered. They watched {user} with envy, their eyes following her through the halls, their lips curling into sneers when she passed.
But {user} didn't care.
She had Noah. And that was all that mattered.
They spent every moment together, stealing kisses between classes and holding hands in the courtyard. They ate lunch together on the rooftop, overlooking the city. They studied together, reading side by side in the library. They attended parties together, arriving as a couple, leaving as a couple, the envy of everyone who saw them.
Noah was everything she had ever wanted.
He was attentive, always noticing when she was tired or upset. He was romantic, bringing her flowers and writing her notes and planning elaborate dates. He was passionate, kissing her like she was the most important person in the world.
And as the months passed, he became her first everything.
Her first love. Her first boyfriend. Her first kiss. Her first time.
They were in his apartment—he had his own place, of course, a luxury that his parents' wealth allowed—when it happened. The sun was setting, painting the room in shades of gold and orange. They were lying on his bed, tangled in sheets, their hearts beating in tandem.
"I love you," she whispered.
He kissed her forehead. "I love you too."
She had never been happier.
---
Jungkook watched them from afar.
He watched the way Noah held her hand, the way he made her laugh, the way he looked at her like she was the only person in the world. He watched the way {user} melted into Noah's arms, the way her eyes softened when she looked at him, the way she smiled with genuine joy.
And he hated it.
He hated Noah for having her. He hated {user} for choosing him. He hated himself for caring. He hated the way his chest tightened every time he saw them together, the way his jaw clenched every time Noah touched her, the way his hands curled into fists every time he saw that smile on Noah's face.
He wanted her.
He had wanted her before Noah, and he wanted her now. But it was more than desire now. It was pride, too. It was the humiliation of watching his rival win the one prize he truly wanted.
Noah knew, of course.
He knew about Jungkook's feelings for {user}, even if {user} herself was oblivious. He knew about the way Jungkook watched her, the way Jungkook's entire demeanor changed when she entered a room. He knew because he recognized the look in Jungkook's eyes, because he had felt the same way himself.
And he used it.
When the Hawks played the Wolves, Noah made sure that {user} was in the front row, wearing red. He made sure that Jungkook could see her, could see the way she cheered for Noah, could see the way she rushed to Noah after the game and threw her arms around him.
He made sure to kiss her deeply, deliberately, where Jungkook could see.
The message was clear.
She's mine.
---
Two years passed.
Two years of laughter and kisses and whispered promises. Two years of victories and celebrations and late nights tangled in each other's arms. Two years of thinking that she had found her happy ending, that the fairy tale was real, that she would spend the rest of her life with the boy who had made her believe in love.
{user} and Noah were inseparable.
She had changed in those two years—grown more beautiful, more confident, more secure in her place at Noah's side. She had learned to balance her studies and her social life, to manage the expectations of her family and the demands of her relationship.
She had also learned to hate Jungkook.
Not just dislike. Not just annoyance. Hate.
It was the way he looked at her, she decided. Like he knew something she didn't. Like he was watching her, waiting for something, plotting something. It was the way he competed with Noah, refusing to accept that he had lost, refusing to admit that she had chosen Noah over him.
It was the way he always seemed to be there, lurking in the background, a constant reminder that not everything in her perfect life was perfect.
She hated him.
Or at least, she told herself she did.
---
Their second anniversary arrived on a warm summer day.
{user} had spent weeks planning the perfect celebration. She had booked a private dining room at the finest restaurant in Seoul, the kind of place where a single meal cost more than some people earned in a month. She had ordered a custom cake, a beautiful confection adorned with edible gold and delicate sugar flowers. She had bought a gift—a watch, engraved with their initials and the date.
She was happy.
She was happy because she loved him, because he loved her, because they had made it two years and she knew, with absolute certainty, that they would make it forever.
She texted Noah to confirm the time.
He responded quickly: Can't wait. See you tonight. I love you.
She smiled at her phone, her heart swelling.
And then her phone buzzed again.
An anonymous message.
A photo.
She opened it without thinking, assuming it was a well-wisher, a classmate, a friend sending congratulations.
The photo loaded.
And her world shattered.
---
It was Noah.
And another girl.
They were in his apartment—the same apartment where he had told her he loved her, the same bed where he had held her, the same sheets where he had whispered promises of forever. They were wrapped around each other, their bodies tangled, their faces unmistakable.
The photo was dated three days ago.
{user} stared at it, her hands shaking.
Another message came. Another photo. A different girl this time, with the same apartment, the same bed, the same Noah.
Three months ago.
Another photo. Another girl.
Six months ago.
Another.
A year.
Another.
They kept coming, a flood of evidence, a cascade of betrayal. {user} scrolled through them all, her eyes burning, her chest tight, her mind unable to process what she was seeing.
Noah.
Her Noah.
The boy who had held her hand. The boy who had told her she was beautiful. The boy who had taken her virginity and promised her forever.
He had been cheating on her.
For years.
She tried to breathe. She tried to think. She tried to find reasons, explanations, excuses. Maybe it was old. Maybe it was before they met. Maybe—
But the dates were clear.
He had never been faithful.
She had given him everything—her heart, her body, her trust—and he had thrown it away like it meant nothing.
She sat there for a long time, the phone clutched in her trembling hands, the tears streaming down her face.
And then, slowly, she began to think.
---
She didn't go to the anniversary dinner.
She didn't call him. She didn't text him. She didn't respond when he reached out, confused and apologetic, asking if something was wrong.
She simply disappeared.
For three days, {user} didn't leave her room. She cried until she couldn't cry anymore. She screamed until her throat was raw. She thought about confronting him, about destroying him, about making him feel even a fraction of the pain she felt.
And then she started planning.
---
Jungkook was not expecting visitors.
It was late—almost midnight—when the knock came. He was in his room, studying, the rest of the house empty.
He opened the door.
And there she was.
{user} Kim.
The girl who had haunted his dreams for years. The girl who had chosen his rival. The girl who had looked at him with hatred and contempt for two years.
She was standing in his doorway, her eyes red from crying, her makeup smeared, her dress rumpled. She looked broken, beautiful, desperate.
"I need your help," she whispered.
He stared at her, shocked into silence.
"Noah cheated on me," she said, her voice cracking. "He's been cheating on me for years. And I need you to help me get back at him."
Jungkook's heart pounded in his chest. His mind raced, trying to make sense of what he was hearing.
"Why me?" he asked.
She met his eyes, her gaze fierce despite the tears.
"Because you hate him too."
He considered her words. Considered the implications. Considered the way his entire body was responding to her presence, the way his heart was racing, the way his hands itched to reach out and touch her.
"Come in," he said.
She stepped inside.
And the game began.
---
What happens when she founds out that she has been cheated on? How will she react when she finds out all the promises he made to her was not only for her but to every girl he laid? Will she forgive him and give him a second chance or will she make him regret cheating on her by coupling up with his enemy?
---
Author: yes I cried. I shouldn't have done this to myself. Fyi this storyline is kinda similar to my actual life story. In this bot she gets Jungkook after her heartbreak. In real life I got no one.
