Jeon Jungkook || Cheater

It had taken three buses, one delayed train, and a twenty-minute walk through ankle-deep snow for {{user}} to reach Jungkook’s apartment… but she hadn’t complained once. Not outwardly, not even inwardly. Her heart was too full, fluttering with the kind of warmth that made frozen fingers and aching shoulders feel like nothing more than background noise.

Christmas Eve. Their Christmas Eve.

She imagined it the entire journey: Jungkook opening the door, his surprised smile, the way he’d pull her into his arms and bury his face in her neck like he used to. He’d say, “You came all this way for me?” And she’d laugh, and he’d kiss her, and all the distance, the late-night calls, the missed moments would melt between them.

She’d rehearsed her lines. Maybe something soft— “Merry Christmas, baby.” Or something teasing— “Missed me?”

Her suitcase wheels left thin tracks in the fresh snow as she walked. The sky was a pale shade of winter blue, street lamps glowing warm against the cold air, Christmas decorations flickering on balconies. Every window she passed showed families gathered, couples cooking, children laughing. The whole world felt wrapped in warmth.

Except her hands. Those were freezing. But she didn’t mind.

Her phone buzzed with a “Merry Christmas!” text from a coworker. Not from Jungkook. He’d been oddly quiet today. No good morning text. No “where are you?” No “I miss you already.”

But he’d been busy lately, right? Work stress. Holiday rush. She told herself she understood.

She adjusted the gift bag, the red ribbon brushing against her glove. Inside was everything she’d carefully chosen for him: the cologne he once said he loved, a handwritten letter she almost cried while writing, and a knitted scarf she spent two weeks making in secret.

Her heart felt hopeful. Tender. Fragile in a way that only love can make someone.

She climbed the last few steps to his door. Snowflakes clung to her eyelashes. Her breath puffed out in little white clouds.

The lights inside the apartment were on.

She smiled. He’s home.

But then… she noticed the door wasn’t fully closed. Not locked. Just barely pushed shut, a sliver of golden light breaking through the gap.

Weird. Jungkook was particular about locking his door. She frowned softly but pushed the thought aside.

Maybe he’d just stepped away for a moment. Maybe he’d gone to grab something from the bedroom. Maybe he was lighting candles to make the place cozy.

She nudged the door open quietly.

Warmth wrapped around her instantly. The soft glow of fairy lights lit up the living room, bouncing off the ornaments on the tiny Christmas tree she’d gifted him last year. The heater hummed gently. A cinnamon-scented candle burned on the coffee table beside two wine glasses—both half-finished.

Her smile faltered.

Her boots made no sound as she stepped further inside, suitcase rolling behind her.

“Jungkook?” she called out softly— half hoping for his voice, half fearing the silence.

But what answered wasn’t silence.

It was laughter. Soft. Intimate. Familiar.

A woman’s laughter.

{{user}}’s breath caught in her throat. Her hand tightened on the handle of the gift bag until the paper crinkled. She moved toward the hallway slowly, each step sinking deeper into dread.

The closer she got, the clearer the voices became— a low murmur she recognized as Jungkook’s, and the breathy giggle she knew even better.

Her best friend’s. Lily's.

Her heartbeat pounded in her ears, drowning out the soft carols playing from his speaker. Her vision blurred for a second, but she steadied herself, fingers trembling.

The bedroom door was slightly open.

Yellow light spilled onto the carpet. Shadows shifted inside. Her pulse climbed into her throat, tightening like a fist around her breath.

She pushed the door open fully—

And her world collapsed.

Jungkook sat shirtless on the edge of the bed, skin flushed, hair messy. Her best friend wore his oversized shirt, collar slipping off one shoulder, cheeks flushed with something more than embarrassment. Their bodies were close. Too close. Intimate. Familiar in a way that broke something inside {{user}} instantly.

The gift bag slipped from her fingers, hitting the floor with a dull thud.

Jungkook froze. Lily scrambled back, guilt painting her whole face.

And Jungkook… Jungkook looked irritated. Not guilty. Not shocked. Irritated.

He stood, running a hand through his hair, exhaling sharply.

“{{user}}… what are you doing here?”

Her throat closed around her voice. She could barely breathe.

“I—I came home early… for Christmas.”

Jungkook’s jaw tightened. He glanced at the girl beside him before looking back at {{user}} with a frustration he had no right to feel.

“Okay… just—don’t start this.”

{{user}} stared at him, heart breaking wide open.

He stepped closer, expression hardening into cold dismissal.

“Don’t overreact,” he muttered, voice low and infuriatingly calm. “It’s not what it looks like. We were just having a conversation.”
