Keeho
You had heard the rumors before. Whispers on social media, blurry photos, and that one fan account that swore they saw Keeho and another idol together after a music show. You brushed it off every time, trusting him. Keeho was always open, always reassuring. “Don’t believe everything you see online,” he had said once, smiling like the truth lived in his dimples. And you believed him.
Until tonight.
You were watching a livestream from some award event—just background noise while you folded laundry. The camera panned across the red carpet, catching a glimpse of idols mingling, waving, laughing. Then, for half a second, there he was. Keeho. Hand in hand with her. Not holding hands like friends. Holding hands like people who had forgotten the world existed.
Your body went cold first. Then the burn came—slow, crawling from your stomach to your throat, until you couldn’t breathe past it. The phone trembled in your hand. You replayed that half-second over and over, hoping the angle was weird, that maybe she had just brushed his hand. But no. Every frame screamed the truth you didn’t want to face.
You sat there for a long time, staring at the wall, feeling the quiet twist tighter around you. Then the sadness curdled into something darker. You started moving—grabbing the hoodie he’d left on your chair, the toothbrush next to yours, his favorite mug that you’d pretended to hate because it was chipped. Everything of his went into a box. No tears this time. Just silence and a steady, shaking rhythm in your chest.
By the time he arrived, headlights cutting across your porch, the box sat outside like a waiting verdict. You didn’t plan to see him—but curiosity was cruel. You peeked through the window as he climbed the steps, confusion spreading across his face. He looked tired, still in his event clothes, hair tousled from the night.
He knocked once, then called your name. You opened the window instead.
“Oh hey,” you said, voice calm in a way that scared even you. “You might want to be more careful at events. Cameras are everywhere, you know.”
He froze, his hand still hovering over the doorknob. “Wait, what are you talking about?” His voice cracked, the kind of crack that begged for a chance to explain.
You laughed—a sharp, tired sound. “You know exactly what I’m talking about.”
He stepped closer to the window, guilt already written all over his face. “It’s not what it looked like, I swear. She—”
You cut him off. “Stop.” The word sliced through the air. “You’re lucky I only threw your stuff out instead of setting it on fire.”
His eyes softened, the way they did when he was trying to fix something with words. “Y/n look....I’m sorry,” he said, and for a moment, it almost sounded real.
You shook your head, the anger keeping you upright. “You can take your sorry and shove it up your ass.” You leaned against the window frame, folding your arms. “Now, if you don’t want another livestream catching you picking through your ex’s porch at midnight, I suggest you take your things and fuck off."
He didn’t move at first. Just stood there, looking at you like he wished he could rewind time. Then he bent down, picked up the box, and whispered your name again, quieter this time.
You shut the window.
His car engine faded down the street, leaving only the hum of the night and your heartbeat, still pounding against your ribs. You stared at the empty porch, the ghost of him already dissolving into the dark, and told yourself this was revenge enough—letting him see exactly what it looked like to lose you.
Theo
You thought the night would be sweet. A small surprise, nothing huge—just coffee the way he liked it, the one with too much caramel syrup, and a box of donuts because you knew he’d been living off studio vending machines again. Theo had texted you earlier that he’d be “working late.” You imagined him humming behind the mic, headphones askew, lost in melody. So you thought: why not show up, be the warmth in his long night?
You even smiled to yourself on the walk there, picturing his reaction—his wide grin, the soft “You didn’t have to, babe,” before stealing a sip of your drink like he always did.
The door to the studio was slightly open, a sliver of light spilling into the hallway. You raised your hand to knock but froze when you heard it—his laugh. Not the polite one. The one that crinkled the corners of his eyes. A girl’s laugh followed, softer, close.
You leaned closer to the door. Through the gap, you saw them. Theo, half-turned toward the producer’s assistant, his arm looped casually around her waist. Her hand rested on his chest, fingers playing with the chain he always wore. They were whispering, faces too close, the air between them heavy with something you’d once thought belonged only to you.
Then he leaned in. So did she.
You cleared your throat. Loudly.
Both of them flinched apart like guilty kids. Theo’s eyes went wide when he saw you standing there, coffee cup in one hand, donut bag in the other. The assistant mumbled something and fled the room like smoke.
You stepped inside, your smile sharp enough to cut glass. “Hi,” you said, voice bright, cheerful, wrong. “Long night?”
“Babe—” he stammered, running a hand through his hair. “I—it wasn’t—she just—”
You held up a hand. “Relax. Everything’s fine.” The fake smile didn’t waver, even as your heart clawed at your ribs. “I actually brought you something.”
He blinked, confused, eyes darting between you and the coffee cup. “What?”
“Your favorite,” you said sweetly. “Extra caramel right?”
Before he could move, you tipped the cup forward, watching the liquid pour across his laptop keyboard in a slow, hissing wave. The smell of burnt sugar and electronics filled the air. Theo just stared, frozen, mouth slightly open.
You set the empty cup down beside the puddle, turned to the box of donuts, and launched them against the wall. Frosting splattered across the soundproof foam in pale pink and chocolate streaks.
For a moment, the only sound was the quiet dripping of coffee from the table.
Theo pushed back his chair, standing. “Okay, I know you’re angry—”
You met his eyes, your voice low now, steady as a loaded gun. “Don’t,” you said. “Don’t come any closer.”
“Can we just talk—”
“I said don’t.” You took a step back, shoulders squared. “Because if you touch me, Theo, your face is going to be the next thing I smash against that wall.”
The words hung between you, sharp and final.
He stopped.
The studio light flickered, catching on the ruined laptop, the donuts sliding down the wall like melting ghosts. You turned to leave, the door creaking behind you.
Theo called your name once—soft, desperate—but you didn’t look back. You’d brought him something sweet, and he’d ruined the taste himself.
Jiung
You were curled up on the couch when your phone rang. It was late, the kind of late where thoughts got louder and the room felt too big. Jiung had texted earlier that he was going out with friends, told you not to wait up. You trusted him. You always did.
Your friend’s voice came out rushed, uneasy. “Listen....I didn’t want to be the one to tell you, but… I’m at the club right now. I saw Jiung.”
Your chest tightened. “Okay,” you said slowly. “And?”
There was a pause. Too long. “He was kissing another woman. Like—making out. I’m so sorry.”
For a moment, everything went quiet. You thanked your friend, hung up, and just sat there. Your hands rested uselessly in your lap. The hurt came first, heavy and suffocating, pressing down until your eyes burned. You pictured his smile, the way he promised loyalty so easily, like it was a given. You felt stupid for believing it.
Then the sadness snapped.
Anger rushed in, hot and electric. You stood up so fast the couch creaked behind you. You didn’t cry. You didn’t hesitate. You went to your room, pulled on something sharp and confident, something that made you feel tall. You fixed your hair, your makeup deliberate and bold. If Jiung was going to embarrass you, you would not arrive broken.
The bass of the club hit you the second you stepped inside. Lights flashed red and blue, bodies pressed together, sweat and alcohol thick in the air. You scanned the room once, twice, until you saw him.
Jiung stood in a dark corner, one hand tangled in another woman’s hair, her mouth on his like nothing else mattered. He looked careless. Comfortable. Happy.
Your jaw tightened.
You walked straight toward them, every step steady. When you reached him, you tapped his shoulder.
Jiung turned around, already smiling—until he saw you. His face drained of color. His mouth opened, probably to say your name, probably to lie.
You slapped him.
The sound cracked through the music, sharp and clean. The club seemed to inhale all at once. Jiung staggered half a step back, hand flying to his cheek, eyes wide with shock. The woman beside him froze, her hand still half-raised, lipstick smeared.
You didn’t say a word.
You turned around and walked toward the exit, heels striking the floor in time with the pounding bass. Behind you, the crowd erupted. Cheers, whistles, laughter. Someone shouted approval. Someone clapped. The club carried you forward like a wave, loud and unapologetic.
Jiung called your name, his voice lost in the noise, cracking with panic. You didn’t stop. You didn’t look back. He didn’t deserve that last glance.
The cold air outside hit your face, grounding you. Your hands shook now, the adrenaline fading, but your spine stayed straight. You had walked into the fire and left without burning.
Inside the club, Jiung stood frozen, cheek red and stinging, surrounded by noise and strangers. For the first time that night, he looked small. And you kept walking, heart pounding, knowing the slap wasn’t just anger—it was the sound of the door closing behind you.
Intak
You had always felt it. The way his phone tilted away from you sometimes. The way his voice shifted when a certain name came up. Intak swore he didn’t talk to his ex anymore. Promised it, hand over heart, eyes wide and sincere. You wanted to believe him. You told yourself that trust meant swallowing the ache and calling it nothing.
Then one afternoon, boredom got the better of you. You checked his location, half-expecting to see the practice room. Instead, a restaurant pin glowed back at you.
Your stomach dropped.
You called him. No answer. You grabbed your keys and drove, knuckles white on the steering wheel, your thoughts racing faster than the traffic. By the time you arrived, you already knew what you would find. Still, the sight hit like a punch.
Intak sat in a corner booth, her body pressed close to his. His arm wrapped around her like it belonged there. She laughed into his shoulder, and he leaned down to kiss her like it was muscle memory. Soft. Familiar.
You walked straight to the table.
“Wow,” you said. “Practice must’ve changed locations.”
Intak jolted like he’d been electrocuted. His face drained of color. “What—why are you here?” He pulled away from her too late.
You looked at him, really looked. “So you lied to me,” you said, calm in a way that scared even you.
He stood up so fast the table rattled. “Okay wait I can explain. It’s not—”
“Don’t,” you cut in. “You already explained when you told me you were somewhere else.”
His mouth opened and closed, apology scrambling over itself. “I’m sorry. I messed up. Please—”
You laughed quietly. “Don't worry honey. I mean I lied to you, too."
He froze. “What?”
You crossed your arms. “I lied every time I told you everything was perfect. I lied every time I said I was happy. I lied every time I told you I had a GROUNDBREAKING Orgasm thanks to you."
His eyes widened, wounded pride flashing through the guilt. “Wait, what the fuck?"
“Uh huh,” you said coolly, “And I'm not even done! Your last solo? It SUCKED!"
The words landed harder than you expected. He flinched.
You tapped your chin, pretending to think. “What else...ooh right! Remember before we started dating and I promised you that San and I had just been friends?"
His breath caught. “Yeah.”
You met his gaze, unblinking. “Oh well, I lied.”
Silence swallowed the table. Even his ex shifted uncomfortably.
“He did fuck me,” you added, voice steady, deliberate. “And unlike you, he made me cum for real.”
Intak’s face crumpled, shock giving way to something raw and helpless. “Why would you say that?”
You picked up your bag. “Because apparently we both are huge fucking liars."
You looked at both of them then, offering a polite, venom-sweet smile. “Enjoy your dinner. I hope it’s worth it.”
You turned and walked out, heels striking the floor like punctuation marks. Behind you, Intak called your name once, desperate and cracked. You didn’t slow down.
The night air hit your face, sharp and cleansing. Your hands shook, but your chest felt lighter. You had said everything you needed to say. And this time, none of it was a lie.
Soul
You were tipsy in the good way, warm and buzzing, packed into a booth with your girls. The music was loud, the lights low, and for once, life felt light. Someone asked about your love life, and you smiled before you could stop yourself.
“You know,” you said, stirring your drink, “I actually just started seeing someone.”
They leaned in immediately. You talked about Soul, about how strange and sweet it felt, how new everything was. How he was quiet but attentive, how you liked the mystery of him. You laughed, cheeks warm, heart stupidly hopeful.
When you excused yourself to go to the bathroom, you were still smiling.
You didn’t expect to see him.
Soul stood near the hallway, half-hidden by shadows, leaning close to another girl. Her hand rested on his arm. He bent down to say something in her ear, and she laughed, fingers tightening like she belonged there.
Your smile fell apart.
For a second, you thought you were wrong. That your brain was glitching. Then Soul looked up and saw you.
His eyes widened.
He stepped away from her immediately and walked toward you, meeting you halfway before you could even move. “Hey,” he said, voice too careful.
You stared at him, your confusion slowly turning sharp. “What is this?” you asked. “Are you on a date or something?”
He hesitated. Too long.
“…Yeah,” he said quietly.
The sound that came out of you surprised even yourself. You laughed. Loud. Broken. It echoed down the hallway, turning a few heads. “You’re kidding me, right?”
He frowned. “I didn’t mean—”
“We literally just started dating,” you said, laughing harder now, disbelief curling into anger. “Like, days ago. Did you forget that part where we said that this is an official relationship?”
He opened his mouth, closed it, rubbed the back of his neck. “I was going to tell you, I just didn’t know how to—”
You tilted your head and mimicked him, exaggerating the pauses, the nervous gestures. “I just didn’t know how to—” You dropped the act instantly. “Wow. Incredible performance.”
“Please, let me explain,” he said, stepping closer.
“Fuck off,” you snapped.
The word landed hard. He froze.
You took a step back, pointing at him. “Don’t do that thing where you act confused. You knew exactly what you were doing.” Your voice shook now, but you didn’t stop. “You don’t get to have me and shop around at the same time.”
“It wasn’t like that,” he said, panic creeping in. “I just—”
You cut him off. “Don’t get near me again. Ever.”
The finality in your voice made his shoulders drop. He stood there, silent, watching as you walked past him toward the bathroom, then straight past that too, back toward your table.
Your girls saw your face and stood up instantly, questions spilling out. You shook your head. “We’re leaving.”
As you walked out, you didn’t look back. You didn’t need to. Soul stayed rooted where you left him, surrounded by noise and lights, realizing too late that new beginnings were fragile things. And he’d broken this one before it even had time to breathe.
Jongseob
Morning crept in quietly. Pale light slipped through the curtains, painting the room soft and harmless. You woke first, as you often did. Jongseob slept beside you, face relaxed, lashes resting against his cheeks like nothing in the world could touch him.
You leaned over and kissed him quickly, a habit born from affection. He shifted but didn’t wake. You smiled faintly and slipped out of bed, padding into the living room.
That was when his phone lit up.
The vibration was small, almost polite. You told yourself to ignore it. You really did. But then you saw the name on the screen.
Minji.
Your chest tightened. You picked up the phone, hesitation buzzing in your fingers. One message. Short. Clear.
Thank you for last night. I had a really good time.
The room felt suddenly too bright. Too loud. Jongseob had told you he was at practice. Complained about how tired he was going to be. Apologized in advance for not texting much.
Your hands went cold.
You didn’t cry. You didn’t scream. You just stood there, staring at the words until they burned themselves into your head. Then you set the phone down carefully and walked back to the bedroom.
Jongseob was still asleep.
You sat on the edge of the bed and watched him for a while. You memorized the rise and fall of his chest, the way his lips parted slightly when he breathed. You wondered how easily he’d slept after lying to you.
Then you stood up.
You grabbed the vase from the dresser, flowers drooping lazily inside it, and walked back to the bed. Without hesitation, you tipped it over.
Cold water crashed down on him.
Jongseob jolted awake with a shout, scrambling upright, hair plastered to his forehead, sheets soaked. “What the fuck—what are you doing?”
You crossed your arms, your voice steady and sharp. “Did you have a good time with Minji?"
Confusion flickered across his face before panic rushed in. “What? No, you don’t understand—”
“You’re disgusting,” you said flatly. “A lying, cheating motherfucker.”
He shook his head, water dripping from his chin. “I didn’t—she’s just—”
“I read the message,” you cut in. “So cut the bullshit.”
His mouth snapped shut. His eyes darted around like he was searching for a version of reality that would save him. “Why were you even going through my phone?"
You laughed once, bitter and short. “Don't you dare make me the bad guy here.”
You didn’t hold back then. Every insult you’d swallowed came spilling out. You told him how small he looked now. How trust evaporated when lies piled up. How disappointing it was to realize that the person you defended so fiercely wasn’t worth the effort.
“I want you out,” you said. “Now.”
He stared at you, stunned. “You’re serious?”
You nodded toward the window. “Don’t forget your phone.”
He turned just in time to hear the distant crack of plastic against pavement. His eyes widened as he rushed to the window and looked down.
You met his gaze, unflinching. “Go get it,” you said. “And don’t come back.”
He stood there, drenched and silent, as you opened the bedroom door and waited. The morning light no longer looked soft. It looked honest.
