synopsis: In their secret college relationship, popular girl Wonyoung and her downbad girlfriend Y/N never interact in public—until a flirty classmate makes a move on Y/N in the library.
Wonyoung’s jealousy explodes, pulling Y/N into a possessive, steamy encounter that risks exposing everything they’ve been hiding.
But today, the rules were testing both of you.
The library on the third floor was always your safe haven—quiet, dim, and far from the chaos of campus life. Especially from her.
Jang Wonyoung.
The girl everyone whispered about, the one who walked through the quad like the whole university was her runway. Popular, untouchable, with that sharp jawline, long legs, and a smile that could make half the student body weak.
No one knew she was yours.
And you made damn sure it stayed that way.
You two had rules: no glances in the hallway, no texts during class, no lingering near each other on campus. At school, you were strangers. Behind closed doors? You were completely, pathetically downbad for her.
You were tucked in the far corner, headphones on, pretending to study for your literature exam when a soft voice interrupted.
“Hey… Y/N, right?” A girl with shoulder-length hair and a confident grin slid into the seat across from you. She was from your psych class—Michaela, you thought. She’d been throwing flirty comments your way for weeks. “Mind if I join? I could use some company… and maybe your notes. I can't understand some lessons earlier.”
You gave her a polite smile, shifting uncomfortably. “Uh, sure. Notes are right here.” You slid your notebook over, keeping it casual. But Michaela leaned in closer than necessary, her fingers brushing yours as she pointed at something on the page.
“You smell really good, by the way,” she murmured, eyes sparkling. “And you’ve got this quiet-hot nerd thing going on. We should grab coffee sometime. My treat.”
Your cheeks heated. Before you could respond, a familiar presence filled the air. You didn’t even need to look up. The temperature in the room seemed to drop.
Wonyoung stood at the end of the aisle, books in her arms, her usual elegant composure cracking just enough for you to notice the fire in her eyes. She was in her signature oversized cardigan and pleated skirt, hair cascading perfectly over one shoulder. Heads turned. Of course they did. She was Wonyoung.
Michaela blinked, clearly surprised. “Oh… Wonyoung-sunbae? Didn’t expect to see you here.”
“Y/N,” she said softly, voice sweet but edged with steel. “We need to talk. Now.”
Wonyoung’s gaze didn’t even flicker to Michaela.
It was locked on you.
That possessive glint—the one she only let out when you were alone—burned bright.
She stepped closer, ignoring the way Michaela’s mouth fell open as Wonyoung reached out and gently but firmly closed your notebook.
Michaela's eyes widened like she’d seen a ghost. “Wait… you two know each other? Like… know each other?”
You didn’t give Wonyoung the chance to answer. Your heart was hammering, a mix of panic and that dizzying thrill she always gave you. You shot up from your chair, grabbed her wrist, and pulled her toward the emergency exit stairs at the back of the library. “Come on.”
“You let her touch you,” she hissed, eyes dark. One hand pinned your waist, the other tilting your chin up. “Flirting back like I wasn’t two shelves away watching every second.”
The door clicked shut behind you, cutting off the whispers. The stairwell was empty, dimly lit, and smelled faintly of old books and dust.
The second you were alone, Wonyoung spun you around, pressing you against the wall with a strength that made your knees weak.
When she pulled back, her lipstick was slightly smudged, and her breathing was ragged. “You’re mine, Y/N. Mine. I don’t care if the whole campus thinks I’m single. They don’t get to touch what’s mine.”
“I wasn’t—” Your protest died the moment her lips crashed into yours. It wasn’t gentle. It was hungry, claiming. Her body molded against yours, thigh slipping between your legs as she kissed you like she wanted to erase Michaela’s existence from your skin.
You melted instantly—god, you were so downbad for her it was embarrassing. A tiny whimper escaped your throat, and she swallowed it, deepening the kiss until you were breathless.
Your hands fisted in her cardigan, pulling her closer. “I know… I only want you, Wonnie. Always.” Your voice came out embarrassingly needy, but you didn’t care. You never did with her.
Wonyoung’s smirk was dangerous. “Good girl.”
She didn’t waste time. Her fingers slipped under your skirt, pushing your panties aside as she found you already soaked. “So wet for me already? Just from me getting a little jealous?” She circled your clit with expert pressure, making your hips jerk. You buried your face in her neck, biting down to muffle your moans as two long fingers slid inside you.
“F-fuck, Wonyoung…” You rocked against her hand, desperate, shameless. She pumped faster, curling just right, her thumb never leaving your swollen clit. The stairwell echoed with the wet sounds and your broken whimpers.
“Look at me,” she commanded. You obeyed, eyes glassy with lust. She was watching you fall apart like it was her favorite view in the world. “Tell me who you belong to.”
“You,” you gasped, thighs trembling. “Only you—ah—please…”
She kissed you again, possessive and filthy, as she pushed you over the edge. Your orgasm hit hard, waves crashing through you while she held you up, murmuring praises against your lips. “That’s it, baby. So perfect for me.”
You were still panting when she withdrew her fingers and brought them to her own mouth, licking them clean with a satisfied hum. Your face burned, but you couldn’t stop staring. Downbad didn’t even cover it.
Before you could drop to your knees and return the favor, the distant sound of footsteps echoed from below. Wonyoung fixed your skirt with careful hands, then cupped your face.
“Tonight. My dorm.” she whispered, pressing one last soft kiss to your forehead. “And if anyone flirts with you again… I won’t be so quiet about it.”
You nodded, heart full and body buzzing. As you both slipped back into the library through different doors, you caught Michaela’s stunned face from across the room. She looked like she’d just watched the impossible.
synopsis: Y/N becomes the ultimate prize in a dangerous game where losing is not an option.
The library smelled like old paper and rainy days, which was exactly why I liked it. It was the only place in East High where I could actually breathe. No drama, no screaming crowds, just me and my Math notes.
Until the chair next to me slid open.
"Hi, Y/N-ah." My heart did a violent flip.
Jang Wonyoung was leaning over my table, her long, curled hair falling perfectly over her shoulder. She smelled like expensive strawberry lip gloss and vanilla.
She was the girl.
The school princess.
Everyone wanted to be her, or be with her.
And for some reason, she was staring at me like I was the only person in the room.
"O-Oh, hi Wonyoung," I stammered, pulling my oversized sweater down over my hands. "Do you need help with the homework?"
"No," she giggled, but the sound didn't reach her eyes. Her perfectly manicured fingers reached out, gently tucking a strand of hair behind my ear.
Her touch lingered a little too long, her thumb brushing against my cheekbone. "I just wanted to see you. You've been ignoring my texts, sweetie. That's not very nice."
"I was just... studying—"
"I don't like it when you look at books more than you look at me," she whispered, her voice dropping into a low, sweet tone that made goosebumps break out on my arms. Her grip on my shoulder tightened, just enough to hurt. "I cleared my whole schedule today just to be with you. You should be happy."
Before I could even process the weird creepiness of her words, a heavy textbook slammed onto the table right next to us.
"Get your hands off them, Wonyoung."
I looked up, my breath catching.
Winter.
If Wonyoung was the sweet princess, Winter was the cool, dangerous girl everyone was secretly afraid of. She was the dance captain, always wearing oversized leather jackets, with a sharp, cat-like stare that could freeze anyone in their tracks. And right now, that stare was fixed entirely on Wonyoung.
"I don't see your name on them," Wonyoung said, her sweet voice instantly turning icy. She didn't let go of my shoulder. In fact, she pulled me a little closer to her side.
Winter let out a dry, dark laugh. She stepped closer, leaning over the table until her face was just inches from mine. "Y/N and I have a deal. She will tutor me on Tuesdays. So back off before I make you."
"Tutor you?" Wonyoung scoffed. "Please. Everyone knows you just use that as an excuse to follow them around. Like a lost puppy."
"At least I don't take pictures of them when they aren't looking," Winter snapped back, her eyes flashing dangerously.
My blood ran cold. "What?"
Winter reached out, her hand sliding under my chin, forcing me to look up at her. Her fingers were warm, but her grip was tight, completely locking me in place. "Don't act so innocent, Wonyoung. I saw your camera roll. You have a whole folder of Y/N. Even photos of them walking home."
"Like you're any better!" Wonyoung stood up, slamming her hands on the table. The polite, angel-like facade she always wore completely vanished, replaced by something dark and unhinged.
"Who do you think scared off Sunwoo last week? He tried to ask Y/N out, and the next day he transferred schools. You did that, didn't you, Winter?"
Winter didn't even look guilty.
She just smirked, her thumb gently tracing my lower lip. "He was annoying. He was in Y/N's space. I just... fixed the problem. I protect what's mine."
"They aren't yours!" Wonyoung shouted, She grabbed my arm, trying to pull me out of the chair toward her.
"Y/N-ah, tell her. Tell her you want to come to my house today. I made your favorite snacks. I know everything you like."
"B-Both of you, stop..." I whispered, my voice trembling. I looked between them, completely terrified.
They weren't just fighting over a crush. They looked insane. Their eyes were wide, dark, and completely hyper-focused on me, like I was a prize they were ready to tear apart.
Seeing the panic in my eyes, Winter's expression softened into something deeply unsettling. She dropped to her knees right next to my chair, grabbing my other hand and holding it against her cheek. "Hey, don't look at her. Look at me, Y/N. I do everything for you. Those bullies who messed with your locker? I took care of them. You don't need anyone else but me."
"No, look at me!" Wonyoung begged, her voice sounding frantic as she squeezed my arm tighter.
"She's dangerous, Y/N. Stay with me. I'll buy you whatever you want. I'll keep you safe in my room where nobody else can ever look at you again."
I tried to pull back, but they both held on. I was completely trapped between the two most popular, beautiful, and absolutely terrifying girls in school.
"So, who is it, Y/N?" Winter whispered, her sharp eyes boring into my soul, a dark, possessive smile growing on her lips.
"Choose right now. Because honestly... we're not letting you leave this library until you do." My chest heaved as I looked from Winter’s sharp, cat-like smirk up to Wonyoung’s beautiful, tight-lipped smile.
The library felt like it was shrinking, the air turning completely suffocating.
"I... I can't," I choked out, trying to pull my hands back. "The bell is about to ring. I have to go to class."
"Class?" Wonyoung let out a soft, breathy laugh that made the hairs on my neck stand up. She leaned down closer, her strawberry scent sickeningly sweet. "Y/N-ah, look around. Do you really think anyone is going to interrupt us?"
I glanced past them toward the front desk. The librarian wasn’t there. In fact, the entire library was dead silent. The heavy wooden doors at the entrance were shut tight.
"I locked it ," Winter said casually, noticing my frantic eyes. She leaned her weight against the table, her leather jacket creaking. "On my way in. No one’s coming in here, Y/N. And you’re not going out. Not until we settle this."
"Are you insane?!" I gasped, my voice cracking.
"Let me go!"
"We’re not insane, sweetie. We’re just devoted," Wonyoung corrected smoothly. She reached up, her fingers sliding into my hair, her grip tightening just enough to anchor my head in place. "You’re so naive. You think you can just walk around this school, being this cute and helpless, and not expect people to want to consume you?"
"I'm not—I'm just a normal person!"
"Not to us," Winter muttered. She grabbed my chin again, her thumb pressing firmly against my jawline. "Wonyoung wants to put you in a glass cage like a pretty little doll. But me? I want to keep you in the dark where only I can touch you. Tell her, Y/N. Tell her how much you liked the little gifts I left in your locker."
"Those... those were from you?" My eyes widened.
For weeks, I had been finding my favorite drinks, expensive highlighters, and handwritten notes detailing exactly what I wore each day.
I thought it was a prank.
"Of course they were," Winter purred, looking incredibly proud. "Also I know everything about you. I know you like to stay up until 2 AM studying. I know you get nervous when people look at you for too long. That’s why I take care of the people who stare."
"Like Minho?" I whispered, horror pooling in my stomach.
"Minho was a mistake that needed to be erased," Wonyoung interrupted, her voice turning completely venomous as she glared at Winter. "But Winter is sloppy, Y/N. She leaves a mess. If you come with me, you won't have to worry about anything. I’ve already talked to my parents. I can get you a scholarship to any university you want, as long as it's the same one I'm going to. We’ll have an apartment together. Just the two of us. I'll take care of your whole life."
"You're planning their whole life without even asking them?" Winter sneered, stepping closer to Wonyoung, their shoulders brushing aggressively.
"They don't want to be your little pet, Wonyoung."
"And they don't want to be your hostage, Winter!"
Wonyoung snapped back, her eyes flashing with a dangerous, psychotic light. She turned her gaze back to me, her expression instantly melting into a creepy, fragile sadness.
"You want to be with me, right, Y/N-ah? Look at how much I love you. I think about you every second of the day. If you choose her... I don't know what I'll do to myself. Or to her. Or to you."
The threat hung heavily in the air. It wasn't a joke.
"Please," I sobbed, tears finally spilling over my cheeks. "Just let me go home. Why are you doing this to me?"
Winter’s expression darkened at the sight of my tears. For a second, I thought she was going to feel guilty, but instead, she just looked deeply unsatisfied. She leaned in until her lips brushed against my ear.
"Don't cry for anyone else, Y/N. It breaks my heart," Winter whispered, her voice low and completely devoid of sanity. "We're doing this because we have to. You're too soft for this world. If it's not us, someone else will take you. So just choose. Pick me, and I'll make sure Wonyoung never bothers you again."
"Don't listen to her!" Wonyoung pulled my arm hard, forcing me to face her. Her face was inches from mine, her beautiful features twisted into something terrifyingly desperate.
"Choose me, Y/N. If you don't... I'll tell the principal that Winter was the one who destroyed the school gym last month. She'll get expelled. She'll be gone anyway. So just save us the trouble and say my name."
"You wouldn't dare," Winter growled, her hand dropping to her side, her fists clenching so hard her knuckles turned white.
"Try me," Wonyoung smiled, a chillingly empty expression on her face. "I get what I want, Winter. Always. And I want Y/N."
They both stared at each other, the tension thick enough to cut with a knife, before their eyes snapped back down to me simultaneously.
They were waiting.
Two gorgeous, popular monsters, completely obsessed, locking me into a corner I could never escape from.
"Well, Y/N?" Winter asked, her voice dropping into a deadly, quiet purr. "Who's it going to be?"
"I... I can't choose," I whispered, my voice breaking completely as a fresh wave of tears blurred my vision. "Please. Just let me go."
Winter’s cat-like eyes narrowed, the dark, possessive look in them deepening. She looked up at Wonyoung, completely ignoring my plea. "She's not going to choose, princess. She's too scared."
Wonyoung sighed, a deeply disappointed but chillingly calm sound. The frantic, desperate expression she wore seconds ago totally vanished, replaced by a strange, placid smile. "I know. It breaks my heart to see them like this. Look at how much they're trembling, Winter. It's not good for their health."
"Yeah," Winter murmured, her grip shifting from my chin to the back of my neck, her fingers surprisingly warm but terrifyingly strong. "We're stressing them out too much. Maybe we should just skip to the final plan."
"Wait—what do you mean final plan?" I gasped, panic surging through my veins. I tried to violently thrash away, to kick the desk, to make any kind of noise, but Wonyoung instantly threw her weight against me, pinning my arms down.
"Shh, it's okay, Y/N-ah," Wonyoung cooed in my ear, her voice a sickeningly sweet lullaby. "We're just going to take you to a place where nobody can ever stress you out again."
Before I could even scream, Winter reached into her oversized leather jacket and pulled out a small, white cloth.
A sharp, chemical smell immediately hit my nose.
Realization hit me like a truck, but it was too late. Winter pressed the cloth firmly over my nose and mouth.
"Just breathe, baby," Winter whispered right against my ear, her deep voice the last thing I heard. "We've got you."
I fought, kicking my legs and trying to shake my head, but Wonyoung held my body down with terrifying strength, whispering sweet, unhinged promises into my hair. “We love you so much... just sleep, Y/N... just sleep.”
My vision began to blur. The edges of the library faded into complete darkness, and my heavy limbs finally went totally numb.
When my eyes finally fluttered open, the first thing I noticed was that my headache was splitting. The second thing I noticed was how incredibly soft the bed beneath me was.
I groaned, trying to sit up, but my body felt heavy and sluggish. The room I was in was massive, decorated in expensive neutral tones, with massive floor-to-ceiling windows showing nothing but a dense, dark forest outside. It definitely wasn't my bedroom.
"Oh, you're awake!"
The door clicked open, and Wonyoung walked in. She wasn't wearing her school uniform anymore; instead, she wore a cozy, oversized cashmere sweater. She carried a tray with a steaming bowl of soup and a glass of water.
"W-Wonyoung?" I croaked, my throat completely dry. Memory came rushing back in a horrific flash—the library, the cloth, the smell. I scrambled backward on the bed until my back hit the headboard. "Where am I? Where is my mom? My phone—"
"Drink some water first, sweetie," Wonyoung said, sitting on the edge of the bed. She ignored my panic completely, holding the glass to my lips. When I refused, her eyes went dark for a split second before she smiled again. "Don't be stubborn. You've been asleep for a whole day."
The door opened again, and Winter walked in, holding a soft blanket. She looked completely relaxed, a faint, satisfied smirk on her face as she walked over and sat on the other side of the bed, effectively trapping me between them again.
"Where are we?!" I demanded, my voice trembling as I looked between them. "And what about your rivalry? Wonyoung, you said she was dangerous! Winter, you said she was a stalker! Why are you guys together?!"
Winter let out a low chuckle, reaching out to lazily wrap a strand of my hair around her finger. "We realized something after you started crying in the library, Y/N. Fighting over you was a waste of time. It was getting messy."
"Exactly," Wonyoung chimed in, leaning closer to rest her chin on my shoulder, her arms wrapping possessively around my waist. "We realized that neither of us was ever going to let the other have you. And since we both love you to the point of insanity... we made a pact."
"A... a pact?" I whispered, my blood turning to ice.
"A compromise," Winter corrected, her eyes boring into mine with absolute, unwavering devotion. "We pooled our money together and bought this house. It's under a private estate, miles away from the city. No one knows we're here. No one is ever going to find you."
"We're going to share you, Y/N-ah," Wonyoung purred against my neck, kissing the skin there softly, making me flinch. "One day you belong to me, the next day you belong to Winter. We share your love, we share your attention, and we both get to keep you safe from the rest of the world. Isn't that perfect?"
"You guys are crazy!" I sobbed, trying to push Wonyoung off me, but Winter immediately grabbed both of my wrists, locking them down onto the mattress with one hand.
"Hey, watch the attitude," Winter warned, though her voice was terrifyingly gentle as she leaned down, her face inches from mine. "We did this for us. For you. Your old life is gone, Y/N. Your school thinks you transferred overseas. Your family... well, Wonyoung's parents have enough money to make missing persons reports disappear."
Wonyoung smiled, tightening her hug around my waist. "You don't need to worry about anything anymore, sweetie. No more studying, no more bullies, no more lonely lunches. You have both of us now. Forever."
I looked at their beautiful, smiling faces, completely paralyzed by the realization of my new reality. There was no escape. I was officially locked in, shared between two monsters who loved me entirely too much.
