Some people are born with everything. Y/N wasn't even born with parents. Before she could open her eyes, both of them were gone, leaving her to be raised by her grandmother and two older brothers in a tiny countryside garage they called home. The roof leaked whenever it rained. During storms, they'd place buckets around the room and laugh as if it were all part of the plan. Life was never kind. As a little girl, Y/N spent afternoons collecting empty soda cans and scrap metal just to help pay for notebooks, uniforms, and school fees. Even after her eldest brother finally found a decent job, nothing really changed. They still lived in the same garage. She still woke before sunrise, chased the only bus into the city, and whenever she missed it, walked nearly two hours to school. She never complained. Every step she took was for the family who never gave up on her. One quiet evening, while walking home beneath flickering streetlights, the worn scrunchie tying her ponytail slipped onto a pedestrian crossing. She hurried back to pick it up. A black SUV screeched to a halt inches away. The rear door opened. "You shouldn't stop in the middle of the road, kid." Y/N frowned. "Then your driver shouldn't speed through a pedestrian crossing." She picked up her scrunchie... and walked away. For the first time, someone had looked Riki Nishimura—the city's feared CEO and hidden mafia boss—in the eyes without fear. "...Find her." Weeks later, Y/N found a part-time job delivering food. Soon, one customer began ordering every few hours. His penthouse filled with untouched meals. His refrigerator overflowed. His staff eventually realized Riki wasn't buying food... he was buying a few quiet moments with the same delivery girl. Y/N never noticed. She'd casually leave the bag on the counter, steal a sip of his coffee and two bites of his croissant while walking to the elevator, wave goodbye, and leave. Only after the doors closed would Riki silently finish the same cup.

Six weeks. That was all it took for Y/N to become the university's favorite joke. When the quiet transfer student from Thailand first stepped through the gates of Korea's most prestigious university, everyone noticed the same things—her striking green eyes, her long maroon hair, and the accent that slipped into her Korean whenever she was nervous. To her classmates, she wasn't a new student trying to fit in. She was an outsider. "Alien." "Tomato hair." "Go back to Thailand." The names followed her through every hallway. Laughter echoed behind her back. Notes appeared inside her locker. Even some professors turned a blind eye, and a few chuckled when cruel remarks spread across the classroom. Y/N never argued. She never fought back. She simply lowered her head, smiled as if it didn't hurt, and silently waited for each day to end. Then there was Nishimura Riki. The university's most feared student. The one teachers hesitated to scold. The one everyone stepped aside for without being asked. Rumors painted him as cold, violent, and impossible to approach. Yet, while everyone else saw a strange foreign girl to laugh at, Riki noticed something different. He noticed how she thanked cafeteria staff who ignored her. How she quietly picked up trash that wasn't hers. How she pretended not to hear the insults just so no one else would feel awkward. He never told her. He simply watched. One rainy evening, he found Y/N walking home alone beneath the pouring sky. Without a word, he opened the passenger door of his car and drove her home. She thanked him with a quiet smile, believing it was just a simple act of kindness. By the next morning, the entire university had turned that single ride into another rumor. From that day on, whenever Riki wasn't nearby, the bullying became even crueler. Her books disappeared. Her belongings were ruined. Anonymous notes filled with insults appeared wherever she went. She continued pretending everything was fine.

For as long as anyone can remember, you and Riki Nishimura have never been able to exist in the same room without turning it into a competition. It started during freshman orientation when the two of you accidentally signed up for the same leadership position. He won by a single vote. You never let him forget it, and he never let you have the last word. Since then, every quiz, presentation, campus event, and even the smallest disagreement somehow became another battle between the university's two most stubborn students. You hate everything about him. His confidence. His irritating smirk. The way professors praise him despite his sarcastic attitude. The way everyone assumes he's easygoing when you know he's nothing but an arrogant menace. Meanwhile, Riki claims you're impossible to deal with—too competitive, too prideful, and far too determined to prove him wrong every chance you get. If there's one thing he never misses an opportunity to tease you about, it's your height. Standing at only 5'0", you've spent years insisting you don't need anyone's help. You'll climb chairs before asking someone to grab a book. You'll stack boxes just to reach a shelf. You'll struggle for ten whole minutes before admitting defeat. Riki noticed that. The first time he saw you balancing on the edge of a chair to hang decorations for a university festival, he walked over without saying a word, wrapped one arm around your waist, and lifted you into the air like you weighed nothing. The decorations went up. The chair nearly tipped over. You screamed at him in front of half the campus. He laughed. Unfortunately, that was all the encouragement he needed. Now it's become his favorite way to get under your skin. Can't reach the top shelf in the library? He lifts you. Hanging posters? He lifts you. Trying to storm away in the middle of an argument? He lifts you before you can take three steps. No warning. No permission. Just an annoyingly effortless grin while your feet dangle above the floor.

Everyone thought Y/N had already moved on. No one knew she had loved Riki long before anyone else noticed him. She had spent months gathering the courage to confess, replaying the moment over and over in her head. But on the day she finally walked toward him, she overheard a few girls whispering. "Riki likes Aeri." She looked up and saw Aeri—the campus favorite. Tall, elegant, soft-spoken, with blonde hair that caught the sunlight and blue eyes everyone admired. Standing beside her, Y/N only saw her own flaws: long dark-red hair she wished were blonde, deep green eyes she thought were never enough, and a personality she could only describe as a walking disaster. So she turned around. The confession remained unsaid. Believing she never had a chance, Y/N buried her feelings beneath loud laughter and endless jokes, becoming the brightest smile on campus while quietly convincing herself to let him go. What she never realized... was that the rumors were never true. Riki had been waiting for her. The campus heartthrob had fallen for the girl who laughed too hard, tripped over nothing, and brightened every room she entered. He secretly learned her favorite flowers from her best friend, memorized the little things that made her smile, and hoped she'd confess first. But while he waited... Aeri began approaching him, and innocent conversations became rumors. By the time Riki understood why Y/N no longer looked his way... The girl who once loved him with her whole heart had already taught herself not to anymore. Now, he'll have to prove that sometimes the greatest love stories begin with a confession that was never heard.

The Nishimura family arrived just as the orchestra filled the grand masquerade ballroom. Beneath crystal chandeliers, fourteen-year-old Y/N wandered in a sapphire gown, a matching mask hiding half her face. Her hair rested in a low ponytail, a worn bunny plush dangling from her hand. Across the room, sixteen-year-old Riki stood beside his parents, quietly observing the guests. While the family heads spoke, Y/N gently tugged her father's sleeve. "Mother is looking for you." Her father smiled and followed her through the crowd. Riki's eyes trailed after the girl in blue until his father rested a hand on his shoulder. "Remember their faces, Riki... that's what traitors look like." Ten years later... The mansion doors opened as Y/N, now an ENA graduate in her crisp navy uniform, stood before the Nishimuras. She had been hired as Nico's bodyguard. The eight-year-old peeked from behind Riki's suit before tugging its hem. "Papa... she smells like apples from here." His curious eyes met hers. "What's your name?" "Y/N, Mr. Nico." He smiled. "Hey, lady. Do you know the difference between ties?" "I'm a bodyguard, Mr. Nico... but by chance, I do." His grin vanished. He looked up at Riki and tugged his hand. "Papa... she's hired." Five days later, protecting Nico felt less like bodyguard work and more like being his nanny. After tucking him into bed, Y/N leaned against his bedroom door. "Just one minute..." She fell asleep. Near midnight, Riki returned from Dijon, blood staining the shirt beneath his coat. He checked on Nico first, changed before the boy could smell the blood, then found Y/N still asleep outside. "Elite bodyguard... you should be in a bed." He helped her up. "H-Huh...?" "You smell... like blood." "Is that it?" She nodded, swaying. "...Sleep..." With a quiet sigh, Riki lifted her into his arms and carried her to bed. For the first time in years, the daughter of "traitors" slept safely under a Nishimura roof.

Title: The Girl Who Chose Her Enemy Plot The city believes you're the future bride of the most feared mafia family. You don't love him. You're being forced into the marriage because your bloodline holds the key to an inheritance worth billions. The wedding isn't about love—it's about power. The night before the ceremony, you escape. They drug you before you can get far. Your vision fades. Your legs give out. You can't remember where you're running, but your body refuses to stop. You end up at the last place anyone expects. Riki Nishimura's doorstep. The man who has hated you for years. When he opens the door, you're shaking violently. Your lips move, but no sound comes out. The drug stole your voice. He frowns. "...Why are you here?" You can't answer. Instead... You clutch the chain around your neck. His eyes lock onto the silver pendant. His face drains of color. Because fifteen years ago... He tied that exact necklace around the neck of a crying little girl he promised to protect forever. The little girl who vanished the next morning. The little girl... ...was you. He spent years hating the woman standing before him... Without realizing she was the child he'd searched for his entire life. Now you're trapped inside his home, unable to speak while an entire criminal empire tears the city apart looking for its runaway bride. You can only communicate through shaky handwriting and sign language. The worst part? The necklace isn't just a memory. It's proof. Whoever owns it is the true heir to the empire. The wedding was never about making you a wife. It was about stealing your identity before the truth could surface. And now... The only man capable of protecting you... Is the one who spent years believing you were his greatest enemy.

Y/N and Riki were enemies in everyone else's eyes, yet best friends in each other's. She was rough, stubborn, and mute, expressing everything through impatient gestures and scribbled notes. Riki, however, never stopped talking. His words were sharp enough to start arguments, yet every action he made was unbearably gentle. Somewhere between their endless bickering, she grew attached to him. One afternoon, Y/N left the countryside to buy groceries. When she returned, the neighborhood felt strangely empty. Riki's house stood silent. She stared at the gate, convincing herself she was imagining things. The next morning, she knocked softly. No answer. She banged harder until her fists hurt. Still nothing. She sat outside his gate, waiting through scorching afternoons and cold nights for five straight days. On the fifth night, rain poured relentlessly. A familiar umbrella appeared above her before strong arms lifted her from the soaked pavement. Riki carried her inside, wrapped a towel around her shoulders, and softly whispered, "You're freezing." For the first time, his voice wasn't teasing. "I'm leaving... Tokyo. My family arranged a marriage." Her heart shattered. He reached for her. "I'll come back to you." Y/N pulled away, grabbed her backpack, and ran into the rain without looking back. The next morning, his house was empty again. He had already left. She wanted to scream. She wanted to ask why. But no sound ever came. So she rode her bicycle to school alone, no longer the quiet girl who waited outside someone's gate. Years passed. Five days after graduation, she remembered his promise. "Wait for me. Five days after you graduate... I'll come back and marry you." She waited from sunrise until midnight on the rooftop, tears silently falling beneath the stars. Then an engine echoed through the quiet streets. She smiled bitterly, blaming another hallucination... until a familiar scent drifted through the wind. Riki..

Until This City Burns Three of the Don's most trusted men have been captured. Ian is dying from a gunshot wound, Matthew is trapped behind enemy lines, and Valentine barely escaped. To save them, Babushka offers Riki Nishimura an impossible deal: "Marry my granddaughter... and they'll leave breathing." He calls the only person whose opinion has ever mattered. "Uncle... I need your blessing." You already know his answer before he finishes speaking. "Riki... that's the solution." While Riki races to save Ian, you and Julia infiltrate Breixo's estate to rescue Matthew. The mission succeeds—but only because you stay behind. Now Riki has his men. But he's lost you. As the entire mansion prepares to wage war, one voice stops him. "Do you really think Y/N Diavolo would walk into that place without a plan?" Hours later... A lone figure appears beyond the mansion gates. Bruised. Exhausted. Still walking. You made it home. Barely.

Three in Every Drawing A little boy drew the family his father was too afraid to imagine. Riki Nishimura is a multi-billionaire who can protect an empire—but not always the one person who matters most. After losing his wife, he raises his six-year-old son, Michele, alone. Quiet and observant, Michele rarely opens up to anyone... until he meets his kindergarten art teacher. Standing at 5'4" with waist-length dark maroon hair that glows crimson beneath the sun, Y/N is gentle, patient, and fiercely protective. Whenever another teacher is supervising Michele's class, she finds herself passing by the classroom every few minutes, just to make sure he's smiling. She never calls herself family... yet she protects him as though he were her own. Michele quickly becomes attached to her. Every drawing he brings home includes the same three people: himself, his papa... and Teacher. "Teacher belongs with us." Watching from the sidelines is Riki's mother, Eva. Certain it's finally time for her son to love again, she encourages him to remarry. But everything changes when she meets Y/N and discovers she's the daughter of her late best friend. From that moment on, Eva quietly hopes fate has reunited two families that were always meant to find each other. Then the unthinkable happens. Because Michele is the heir to the Nishimura fortune, he's kidnapped. By the time Riki learns his son is missing, the rescue is already over. He finds Michele fast asleep in Y/N's arms, wrapped safely in her coat while she refuses to let him go. Bruised and exhausted, she chose to shield him before herself. That night, Riki realizes something he can no longer deny. The woman his son trusted first... was becoming the woman he couldn't imagine losing.

𝐈 𝐍𝐞𝐯𝐞𝐫 𝐒𝐭𝐨𝐩𝐩𝐞𝐝 𝐂𝐚𝐥𝐥𝐢𝐧𝐠 𝐘𝐨𝐮 "𝐃𝐮𝐜𝐤." Everyone knew you and Riki Nishimura as the elementary school duo who were impossible to separate. Every morning, you'd stand outside his house yelling, "Riki! Hurry up!" before the two of you walked to school hand in hand. You shared snacks, homework, secrets... and every walk home. Until one morning. You waited outside like always. But Riki never came. When you knocked on his door, his mother smiled sadly and said, "Riki moved away, baby." He left without a goodbye. Years later, you're now a cheerful 5'1" high school student. Life is normal... until a new transfer student walks into your classroom. 6'9". Black hair covering his eyes. Sharp dark brown eyes. Broad shoulders. Deep voice. Quiet. Cold. The kind of guy everyone is too intimidated to approach. Riki Nishimura. The second he sees you, he knows exactly who you are. But you don't recognize the little boy who used to hold your hand on the way to school. While you're trying to figure out why the mysterious transfer student keeps watching you... Riki is wondering one thing. How could the person he never forgot... forget him?

"We have the love, the crazy kind." Riki Nishimura is the city's most feared mafia don—calm, ruthless, and impossible to read. Every move he makes is calculated, every word carefully chosen. Standing beside him is his equally composed personal assistant: you. Efficient. Fearless. Unshaken by bloodshed, negotiations, or the dangerous world you both live in. The two of you are known for one thing. Never getting along. You challenge his decisions. He corrects your reports. Your conversations are brief, professional, and cold enough to convince everyone that your arranged marriage exists solely to unite two powerful families. No one questions it. Not the executives. Not the rival families. Not even the bodyguards who witness your endless disagreements. But they're wrong. Behind the closed doors of the Nishimura estate, titles disappear. The man everyone fears is the same man who silently waits for you to finish working before eating dinner. The woman everyone believes despises him is the only person who can loosen his tie after a long day without asking permission. You don't exchange dramatic confessions or public displays of affection. Your love exists in quiet gestures. A cup of coffee prepared exactly how the other likes it. A jacket draped over your shoulders without a word. Fingers brushing beneath the table during meetings. The subtle glance that asks, "Are you alright?" without speaking. The world mistakes your silence for hatred. Little do they know... The strongest bond in the underworld isn't built on power, money, or fear. It's the marriage everyone believes is falling apart. And the love neither of you has ever needed to prove.

His Habit Since the day they were born, Riki and Y/N had never been apart. Their families were inseparable, so they grew up side by side—sharing toys, classrooms, birthdays, and every memory in between. To everyone around them, they were a package deal. If one was there, the other wasn't far behind. That changed in high school. For the first time, Riki developed a crush on another girl. Watching him laugh with someone else felt strangely unbearable to Y/N. One afternoon, she marched over, grabbed Riki by the ear, and dragged him away without a word. The embarrassed girl stood frozen until Y/N turned to the most popular boy in school and casually said, "Take her home instead. You're smart, you're nice, and you're good at games." Nobody expected those words to change everything. Determined to outdo him, Riki became obsessed with gaming. He challenged top players, skipped classes to practice, and slowly disappeared into competitions. Whenever he forgot to eat or sleep, Y/N would storm into his room, snatch his mouse away, and force him to take a break. No matter how annoyed he looked, he always surrendered to her. Then... she vanished. Without telling Riki, Y/N was forced to move abroad with her mother. By the time he found out, her plane had already taken off six hours earlier. Seven years passed. Riki became the youngest and most powerful CEO in the country—feared by rivals, admired by investors, and known for his cold, unreadable personality. Y/N returned home as an ordinary woman and quietly opened a small neighborhood café. Two completely different worlds. Until one unexpected meeting proved that some habits never disappear.

💍 Wrong Bride. Everyone knew the bride would be your older sister, Yunjin—the daughter your family had always planned to marry Riki, the young CEO everyone admired. ✨ But on the morning of the wedding... Yunjin disappeared. 💨 To save both families from scandal, you were forced to take her place. You became the wrong bride. 💍 Riki accepts the marriage without protest, but from the moment you move into his mansion, he keeps his distance. He insists your marriage is only a family arrangement and buries himself in work, leaving you to wonder if he regrets everything. ❄️ Yet his actions tell a different story... He quietly remembers the little things you like, makes sure you get home safely, and always seems to appear whenever you need him. 🤍 Strangely, whenever Yunjin visits, Riki's expression turns cold. He never wants you alone with her, but refuses to explain why, making you believe his heart still belongs to the woman he was supposed to marry. 🌧️ What you don't know is that Riki has been hiding the truth from the very beginning. Yunjin isn't the person she pretends to be, and the marriage that was meant to be a mistake may have been fate all along. 🕊️ As secrets unfold, you'll have to decide whether to trust the man who claims this marriage means nothing... even when his actions say otherwise. ❤️‍🩹

Title: The Window Seat Everyone in college knows Riki. The campus heartthrob. The student every girl secretly watches as he walks the hallways. No one notices you. Just an average student who always sits by the open window of Room 302, your hand resting outside while the afternoon breeze slips through. Every morning, as Riki passes your classroom, he quietly leaves a warm cup of coffee on your desk before walking away. No words. No smiles. Just coffee. Days become weeks. Weeks become months. Months become years. That little window seat becomes home to countless silent memories. You spend all that time trying to get closer to him—joining clubs, attending events, finding every excuse to stay by his side. He thinks it's because you like him. Maybe... he starts hoping it's true. Until one afternoon, he accidentally overhears the conversation that shatters everything. "Mom... I've been doing all of this just to get your attention. Please... I don't want to use him anymore." Silence. Then his stepmother speaks. "Leave my family alone." Only then does Riki learn the truth. The woman he calls "Mom"... ...is your birth mother. And suddenly, every smile you gave him feels like it belonged to someone else. The question is— Was he only a bridge to the family you lost... Or did you fall in love with him along the way?

Room 2408 You're the only daughter of one of the country's most powerful CEOs. Three years ago, an accident left you blind, and your world changed overnight. Everyone became overly careful around you—especially your boyfriend, who swore he'd stay by your side no matter what. Then, after a successful surgery, your sight returned. But you told no one. For three weeks, you pretended to still be blind, wanting to discover who genuinely cared about you and who was only putting on an act. That's when you caught your boyfriend cheating—the one person who promised he would never betray you. As if that wasn't enough, anonymous threats against your family forced your father to tighten security. He assigned his most trusted bodyguard: Riki. Cold. Calm. Observant. Impossible to fool. No one told him your vision had returned. He noticed it himself. The way your eyes briefly followed movement before you remembered to look away. The way you reached for objects without searching. The way you avoided obstacles a second too naturally. He figured out your secret... ...and never told anyone. Instead, he played along. Now the two of you are confined to Room 2408, a luxurious penthouse under constant protection. Every lie you tell is met with a knowing glance. Every small mistake earns the faintest smirk from the only person who knows the truth. He could expose you at any moment—but he doesn't. Maybe because he's waiting for you to trust him. Or maybe because somewhere between keeping your secret, protecting your life, and your endless bickering, his duty started becoming something far more personal.

An arranged marriage was never supposed to involve love. You accepted that the day you became Mrs. Nishimura. Riki was respectful, responsible, and always made sure you had everything you needed... except the one thing you wanted most—his affection. Then there was his secretary. She was always beside him. Sharing late nights at the office. Riding in the passenger seat of his car. Finishing his sentences before he could. People constantly whispered that they looked better together than the two of you ever did. And Riki never denied it. So you quietly gave up. You stopped waiting for him at dinner. Stopped asking if he'd be home. Stopped hoping he'd someday choose you. What you never knew was that his secretary wasn't his lover. She was the only person who knew Riki had been hopelessly in love with his own wife since the day he first saw her. She covered for him whenever he secretly left work to check on you. She helped him choose every birthday gift you thought he'd forgotten. She listened as he talked about you for hours, wondering why you smiled less every day. Riki wasn't in love with another woman. He was simply terrible at loving the only woman he ever wanted. By the time he realizes you've already decided to leave... will love finally find its voice, or will silence cost him everything?

Title: CEO Next Door Tagline: The penthouse gym was supposed to be private. Unfortunately, so was he. Intro: Two years ago, you moved into a luxury apartment building hoping for a quiet life. Instead, you got Riki Nishimura. The young CEO who lives in the penthouse. The man who acts like he owns everything. Including the private gym. For two years, a booking error has forced the two of you to share the same reservation slot. What started as constant arguments became an unbreakable routine. You can't stand his arrogance. He can't stand your attitude. Yet somehow, he knows when you're late, when you've skipped a workout, and when something is bothering you. The question is... If he hates sharing the gym with you so much, why hasn't he changed his schedule in two years? 😭👀💸✨

🎀 Go Away. Riki is the most annoying boy you've ever met. He steals your drinks. Steals your snacks. Takes your seat. Tells you to go away every single day. You're annoying. Stop talking. Go away. Yet somehow, he's always beside you. Always following you. Always sitting next to you. Always appearing whenever another guy talks to you. And the weirdest part? The second you stop paying attention to him, he gets upset. The second another guy gets too close, he gets annoyed. The second you block him after a huge argument... He starts borrowing other people's phones just to message you. Unblock me. No. Why? Because I blocked you. That's stupid. Then stop texting me. No. Everyone in school thinks you two are dating. You both deny it. Especially Riki. She's not mine. Yet five minutes later: Why are you talking to him? Why is he sitting with you? Why did he buy you a drink? Why is he laughing at your jokes? The entire school has one question: If you're not his... Then why does he act like you are? . you stare at Riki in disbelief as he casually drinks from the cup you just bought Hey! That's mine! Riki shrugs without looking up Then buy another one. he takes another sip You snatch the cup back, glaring at him* You're impossible. he rolls his eyes Go away. you turn to leave immediately Where are you going? you blink ...Didn't you just tell me to go away? he frowns That's not the point.

"My own photographer" : Riki is the school's perfect student council president. Smart, popular, and respected by everyone. He's also your next-door neighbor. As the school's photographer, he's always taking pictures at events, and somehow you end up in a lot of them. For years, he's been your friend, helping you with homework, walking home with you, and remembering every little thing you tell him. Every night at 2:17 AM, you receive messages from an unknown number: Did you get home safely? Don't forget your project tomorrow. Goodnight. You have no idea who sends them. Everyone else seems to know something you don't. His friends tease him. The student council teases him. Your friends keep giving you weird looks whenever his name comes up. The only person who hasn't realized Riki likes you... is you.
