After Hours | idol!Hongjoong x Producer!Reader | fluff
After midnight, KQ Entertainment felt like a different city. The elevator carried Y/N up to the production floor with a soft mechanical hum, and her guest access card warmed in her palm as if it could reassure her. A staff member had shown her the rules earlier sign in, don’t wander, no photos then pointed her to a studio at the end of a quiet hallway.
“It belongs to one of our producers,” the staffer had said. “He’s not using it right now. You can work there tonight.”
Y/N had recognized the number on the door and swallowed his name like a secret. Now she walked the dim corridor alone, carpet eating her footsteps, heart beating too loudly for a building that slept.
Inside, the studio smelled like coffee and clean electronics. Her DAW glowed on two monitors, track lanes stacked neatly, the session titled with an unglamorous draft name. A pre-debut girl group track, bright, confident without sounding like it was trying too hard and strong. KQ wanted options while they shaped the team, and Y/N wanted to give them something that could become the group’s backbone.
The chorus worked. The hook opened up like curtains pulling back, and she loved the little lift on bar two. But the pre-chorus was a wall. Every attempt at tension felt either thin or muddy, like she couldn’t find the right kind of air.
She clicked play again, listened, then stopped it with a frustrated exhale. She tried a new synth progression, deleted it. Tried another, deleted it. Her eyes stung from the screen. On her phone, an tiny group chat lit up with memes, and she almost laughed at the timing her old life pressing against this new one. She set the phone face down and leaned in, stubborn.
A faint click came from the hallway.
Y/N froze, fingers hovering over the mouse. Security existed, night staff existed, but footsteps on this floor still felt like being caught in a dream. The door handle moved.
The studio door opened, and Hongjoong stepped in as if he’d walked this path a thousand times which he had. A black hoodie, hair slightly mussed, a canvas tote in one hand. His gaze swept the room, landed on the monitors, and then on her. Surprise flickered, then softened into curiosity.
“Oh,” he said quietly. “Sorry. I thought this room was open.”
Y/N stood up too fast, chair rolling back. “I’m so sorry,” she blurted in formal Korean. “The staff told me I could work here. I’m a guest producer. I’ll leave—I’m almost done.”
He blinked, then released a breath that sounded like a laugh he didn’t want to echo. “You don’t have to run away.” He closed the door behind him with care. “If they gave you permission, you’re fine. I just came to grab something.”
Her ears burned. “I didn’t know this was your room.”
“It is,” he said simply, then looked at her again as if connecting pieces. “You’re Y/N, right? The producer they invited.”
She nodded. “Yes. I’m working on the track for the new girl group project.”
“Mm.” He stepped closer, not crowding her, but the space still charged. His eyes drifted to her screen. “You’re working late.”
“I couldn’t sleep,” she admitted. “And I want it to be good.”
Something in his expression shifted, understanding. “Can I hear what you have so far?”
The question hit like a gentle shove. Hearing her work wasn’t just an honor; it was terrifying. She’d memorized his credits like other people memorized birthdays. But he asked like it was normal, like music was meant to be shared.
She swallowed. “Of course. It’s still rough.”
“Rough is honest,” he said, and hovered near the desk.
The intro filled the room: soft pad, tight kick, bass line steady as a pulse. She watched his face more than the waveform. He listened with his head tilted, fingers tapping silently against his thigh. When the verse melody came in her own placeholder vocal, gentle and imperfect, his eyes sharpened.
When the chorus ended, he nodded once. “That hook is strong. It opens up nicely. It feels like sunlight, but it’s not childish.”
Y/N let out a startled laugh. “That’s exactly what I wanted.”
“What’s bothering you?” he asked.
She clicked to the pre-chorus. “Here. I want tension, like we’re climbing. But it gets muddy, or it feels empty.”
Hongjoong leaned closer, studying the track list. “You have a lot of midrange fighting,” he murmured. “Pad, pluck, vocal layers. Maybe you don’t need all of them at once.”
“I tried cutting the pad,” Y/N said. “Then it collapses.”
“Because it’s holding the space.” He glanced at her. “You can hold space with rhythm, too.”
He reached toward the mouse, then stopped, looking at her like he was asking permission without words. Y/N nodded quickly. “Please.”
Hongjoong sat in the chair and moved through the session with practiced ease. He soloed tracks, muted others, nudged the drums earlier by a fraction. A hi-hat pattern appeared, then softened as he adjusted velocity. The pre-chorus played again, and suddenly it felt like a runway instead of a wall - motion, lift, breath.
Y/N’s mouth fell open. “Oh my god.”
He leaned back, faintly amused. “It’s your song. I’m just moving furniture.”
“It’s so much better,” she whispered.
“Your instincts are good,” he said, eyes bright in the monitor light. “You already had the shape. You just needed it to move.”
She grabbed her notebook and scribbled notes even though she could see everything on screen. Her hands were shaking from adrenaline. “Thank you. Seriously.”
Hongjoong nodded, then pointed at the chorus synth layered with a clean guitar sample. “Why this sound? It’s more mature than what people expect from pre-debut.”
Because I think they shouldn’t pretend to be small, she almost said. Instead she took a breath and said it properly. “Girls can be bright and still be powerful,” Y/N replied. “I wanted confidence that feels natural, not forced.”
He watched her for a moment, then nodded slowly. “That makes sense.”
Silence settled, not awkward, just late-night quiet. Y/N became aware of how surreal it was: alone in a studio with someone she’d once screamed for in an arena. Yet he treated her like a colleague, not a fan.
“It’s almost two,” Hongjoong said, glancing at the clock. “Do you present tomorrow?”
“In the afternoon. They want a draft. I still need to polish and record a cleaner guide vocal.”
“You recorded the guide?” he asked.
She nodded, suddenly self-conscious. “Just to map the melody.”
“It’s clean,” he said, surprising her. “You’re on pitch. The tone fits.”
“I’m not a singer,” she blurted. “I can carry a melody, but-”
“You don’t have to be perfect to be useful,” he said, thoughtful. “People learn.”
The word learn lingered in the air like a door half-open.
He turned back to the screen. “Let’s listen from the top with the changes,” he said. “If you want.”
“I do,” Y/N said, and meant it.
The next hour became pure work. They tightened transitions, trimmed clashing frequencies, sharpened the second verse so it didn’t sag. When she hesitated, he didn’t push; he asked questions that pulled answers out of her.
“What do you want the listener to feel here?”
“Where does the breath go?”
“Is this a smile, or is this a promise?”
Every question made her focus, made her stop chasing the “right” answer and start chasing the feeling.
Around three, Hongjoong found instant coffee packets in a cabinet and poured two paper cups. “Do you drink coffee?” he asked.
“Yes,” Y/N said with a tired laugh. “I don't really like coffee, but I need it. Especially at this time.”
They sipped carefully, leaning against opposite sides of the desk. The coffee was too sweet, but it warmed her hands.
“You’re not from Korea,” Hongjoong said gently. “Where are you from? Europe?”
Y/N blinked. “How did you know?”
“Your accent,” he said. “And someone mentioned it earlier. Berlin, right?”
“Yes,” she admitted. “I grew up there.”
“I've been there,” he said. “Tour.”
The words slipped out before she could catch them. “I was at that concert.”
She cringed. “Sorry. That’s unprofessional.”
Hongjoong looked more amused than annoyed. “It’s not unprofessional to enjoy music,” he said. “Were you an atiny before you became a producer?”
She stared into her cup. She could lie and keep things clean. But the hour was soft, and he’d treated her work like it mattered. Honesty felt safer than pretending.
“Yes,” she said quietly. “I still am.”
“Is that why you’re nervous?” he asked.
“I don’t want you to think I’m here because I’m a fan,” Y/N said. “I’m here because I can do the job. But you’re… you.”
Hongjoong laughed under his breath, a little embarrassed. “I’m just tired,” he said. Then, more seriously, “I can tell you’re here to work. Fans don’t stay up fixing pre-chorus problems.”
Relief loosened her shoulders. She smiled.
They went back to the track, and this time the pre-chorus finally opened. A simple rising synth, a breathy texture that climbed, then Hongjoong’s idea, a half-beat of silence right before the chorus. The pause made the hook hit like a sunrise.
Y/N played it back again and again, grinning wider each time. “That’s it,” she said. “That’s the feeling.”
Hongjoong nodded, satisfied. “Now it’s inevitable.”
They kept chasing the smallest details, just as producers did when they cared. Hongjoong asked her what kind of voices she imagined in the chorus- airy? nasal? strong- and Y/N described the trainees she’d met in brief, careful phrases: one with a husky lower register, one with a bright smile that showed up in her tone, one with a surprisingly sharp rap cadence. Hongjoong listened, then suggested she leave space in the instrumental where each color could shine.
“Don’t make the track do all the talking,” he said. “Let the members talk, too.”
Y/N nodded and moved a synth line down an octave, clearing room for a future ad-lib. She added a simple clap on the backbeat and watched the groove snap into place. Hongjoong hummed along, then tapped the desk. “Try a call-and-response here,” he suggested, marking a bar with the cursor. “Even if it’s just a placeholder. It will guide them when they record.”
So Y/N recorded a quick “hey” and “yeah,” stacking them lightly, laughing when her own voice sounded too shy. Hongjoong didn’t tease. He just adjusted the timing by a few milliseconds and grinned when it landed perfectly.
“See?” he said. “It’s not about being loud. It’s about being clear.”
They listened through once more, and when the final chorus hit, Y/N felt her shoulders drop for the first time all night. The song didn’t feel like homework anymore. It felt like a stage waiting to be built. For a second, she forgot the fear and only heard possibility, ringing in her chest.
She saved the project under a new version number, then backed it up twice, hands moving like ritual. When she turned back, Hongjoong was watching her with an expression she couldn’t name, something gentle, something like respect.
“You work like you’re chasing something,” he said.
Y/N’s smile softened. “I am.”
For a moment, neither of them spoke.
Hongjoong leaned back against the desk, arms loosely crossed. “Can I ask you something?” he said, voice quieter than before.
“Why producing?” he asked. “I mean, why did you choose this path?”
The question caught her off guard. She stared at the monitor, where the empty timeline now sat like a finished road. Her reflection stared back at her, faint and a little tired.
Then she exhaled slowly. “Because it was the one that stayed open.”
Hongjoong didn’t interrupt.
“I wanted to be an idol,” she said, the words softer than she’d ever said them out loud. “For a long time. I auditioned. A lot.” She laughed quietly, but there was no humor in it. “I kept getting the same feedback. That I was talented, but… too old.”
His brows knit together. “Too old? You don't look that old.”
She nodded. “I was born in 2001.”
There was a beat of silence.
Then Hongjoong let out a short breath. “That’s not old.”
She smiled faintly, not quite meeting his eyes. “It is, apparently. At least in audition rooms. After a while, I stopped trying. Producing felt… safer. Still music. Still close enough.”
She looked back at the screen. “And honestly, being a producer is cool too. I get to create. I get to work in the industry. It’s not like I failed completely.”
Her voice was steady, but something in the way she stood too still, shoulders slightly tense, betrayed her.
Hongjoong watched her quietly.
He saw the way her fingers rested on the edge of the desk, as if grounding herself. The way her eyes lingered on the waveform that wasn’t there anymore, like she could still hear it playing. The way she spoke about giving up as if it were a reasonable, logical decision, not a loss.
“You know,” he said carefully, “being a musician doesn’t come with an expiration date.”
She turned toward him then. “Maybe not. But idols do.”
He didn’t argue right away, because he knew she was kinda right. He just looked at her, really looked. Not as a producer, not as her being a fan, not as someone passing through the building late at night. Just her. The way her face softened when she talked about music. The way her entire focus sharpened when she worked. The quiet hunger behind her calm professionalism.
“You shouldn’t have been told that your dream had an age limit,” he said finally.
Y/N shrugged lightly. “It’s okay. I’ve accepted it.”
But Hongjoong could tell she hadn’t. Not really.
She glanced at the clock and straightened. “I should go. Tomorrow’s going to be a long day.”
He nodded, though something in his expression lingered, thoughtful, distant. “You did well tonight,” he said again, slower this time. “Not just with the song.”
“Thank you,” she replied, sincere. “For everything.”
She gathered her things, slinging her bag over her shoulder. At the door, she paused, hand resting on the handle.
“Good night, Hongjoong,” she said.
When she stepped into the hallway, her footsteps faded quickly.
Hongjoong stayed where he was.
He turned back to the monitor, reopening the session, listening once more to the track they’d shaped together. But his thoughts weren’t on the arrangement anymore.
On the way her voice had sounded when she said I wanted to be an idol.
On the way she’d convinced herself that settling was the same as choosing.
He closed the project and shut down the screen.
Too old, he thought, jaw tightening slightly.
As he turned off the studio lights, one thing was already clear to him.
He was going to help her.
And not just because of the song.
Morning arrived without mercy.
Y/N woke up before her alarm, heart already racing, as if her body had decided to rehearse panic before her mind could catch up. For a few seconds, she lay still, staring at the ceiling, listening to the distant sounds of traffic and life resuming its normal rhythm. Everything felt painfully ordinary for a day that could quietly change everything.
Her laptop sat on the desk across the room.
Inside it lived the song.
She got up, showered, and dressed with unusual care. Not because anyone had asked her to, but because today mattered. She tied her hair back, checked her reflection, and reminded herself that this wasn’t an audition. She wasn’t here to prove her worth as a person. She was here to present work. Music. Something tangible.
Still, her hands trembled as she packed her bag.
At KQ Entertainment, the building felt completely different in daylight. The intimacy of the night before was gone, replaced by movement, voices, footsteps echoing down hallways. Staff members greeted each other, carried equipment, laughed softly. Posters and awards lined the walls. Evidence of dreams that had already made it.
Y/N signed in at the front desk and received a visitor badge. It felt heavier than it should have.
She was guided to a mid-sized conference room fitted with professional speakers and a large screen. Three members of the A&R team were already seated, along with two project managers she recognized. Everyone smiled politely, professionally.
“You can begin whenever you’re ready,” one of them said.
Y/N set up her laptop, connecting cables with careful precision. Her heartbeat echoed in her ears. She took a breath and looked down at her notes, then decided she didn’t need them.
She introduced the track calmly, explaining the intention behind it: a foundation song for a group still finding its identity. Something flexible. Something that didn’t box the members in before they even debuted.
As she spoke, the door opened quietly.
She didn’t turn immediately, but she felt the shift in the room.
When she finally glanced up, Hongjoong stood near the back, hands in his pockets, dressed simply in black. He didn’t draw attention to himself. He didn’t interrupt. He just met her eyes briefly and nodded once.
She turned back to the screen and pressed play.
The intro filled the room, clear, balanced, confident. Y/N forced herself to watch the people in front of her instead of the waveform. She noticed small things: someone tapping their finger unconsciously to the beat, someone leaning forward slightly.
When the chorus hit, one of the A&R directors raised their eyebrows.
The pre-chorus built smoothly now, tension rising without confusion. The half-beat pause before the chorus landed exactly where it should, sharp, intentional. The room seemed to hold its breath for that fraction of a second.
When the song ended, silence followed.
Not the uncomfortable kind. The listening kind.
“I like it,” one of the staff members said.
“Yes,” another added. “It doesn’t sound like a demo.”
Y/N nodded, pulse racing. “Thank you.”
They asked questions about structure, about how adaptable the song would be if the lineup changed, about how she envisioned line distribution. Y/N answered steadily, explaining her choices clearly, confidently. She spoke about leaving space for individuality, about not overpowering voices that hadn’t been discovered yet.
At some point, she realized something startling.
She wasn’t afraid anymore.
She wasn’t shrinking. She wasn’t apologizing for her ideas. She was simply explaining them.
“Who recorded the guide vocal?” one of the directors asked.
Y/N hesitated for half a second. “I did,” she said. “Only as a reference.”
“It fits well,” the director said. “Your tone suits the track.”
Her chest tightened. “Thank you.”
The discussion continued, concepts, future adjustments, possible choreography. It felt less like an evaluation and more like a collaboration. Y/N almost forgot why her heart was still beating so fast.
Then one of the directors leaned back in their chair.
“Y/N,” the director said, “may I ask you something not directly related to this track?”
Her stomach tightened. “Of course.”
“There is still flexibility within this project,” they continued. “The girl group lineup has not been finalized yet.”
She nodded slowly, listening.
“Given your musicality, vocal tone, and overall sense for performance,” the director went on, “we wanted to ask, would you be open to being considered as a member of the planned girl group?”
For a moment, Y/N couldn’t speak.
“I…” She inhaled shakily. “I didn’t expect that question.”
“We’re not making any decisions today,” they clarified. “But we felt it would be a mistake not to ask.”
Her mind flashed with memories she hadn’t touched in years. Small practice rooms. Audition numbers. Polite smiles followed by gentle rejection.
She took a breath. “I would need time to process,” she said honestly. “But… yes. I would be open to talking.”
The director nodded. “That’s all we wanted to know.”
The meeting concluded shortly after. Next steps were outlined, and Y/N was asked to follow up later that day for a private discussion. She gathered her things, feeling strangely light and unbearably heavy at the same time.
When she stepped into the hallway, the noise of the building rushed back in.
Hongjoong waited a few steps away.
“You did well,” he said quietly.
She let out a shaky laugh. “I think my brain stopped working halfway through.”
“It didn’t show,” he replied.
They walked side by side for a moment.
“I didn’t expect that question,” she admitted. “I thought… that door was closed.”
He glanced at her. “Some doors only look closed.”
She stopped walking and turned to face him. “You had a hand in this,” she said softly. It wasn’t an accusation. Just a realization.
He didn’t deny it. “I suggested they look closer,” he said. “That’s all.”
Her eyes filled slightly. “Thank you.”
“You don’t need to thank me,” he said. “I didn’t give you anything you didn’t already have.”
A staff member approached then, asking Y/N to follow them. She nodded, then looked back at Hongjoong.
“I guess this is where things change,” she said quietly.
He met her gaze. “Or where they finally start.”
As she walked away, her heart pounded not with fear, but with something dangerously close to hope.
They didn’t let the moment stretch too long.
After the private conversation, after the polite goodbyes and the quiet shock that still buzzed under Y/N’s skin, a member of the staff approached her again. This time, they didn’t lead her into another meeting room. They stopped in the hallway instead, voices lowered, posture relaxed.
“There’s no pressure,” they said first, as if reading her mind. “We’re not asking you to decide anything today.”
Y/N nodded slowly, hands clasped together in front of her.
“But,” they continued, “if you’re open to it, we’d like to invite you to spend today with the planned girl group as a trainee. Just one day. You can join the training sessions, observe, participate as much as you feel comfortable.”
Her heart skipped. “Today?”
“Yes. Now, if you’d like,” they said gently. “At the end of the day, you can tell us how it felt. Then you can decide whether this is something you want to pursue or not.”
A trial.
Not a contract.
Not a promise.
Y/N swallowed. “Okay,” she said, before fear could catch up. “I’d like that.”
The first dance studio hit her like a wall.
Music echoed loudly, sharp and relentless. The mirrors reflected everything, every movement, every mistake, every hesitation. The other trainees were already warming up, bodies loose and practiced, stretching like this was as natural as breathing.
Y/N stepped inside, suddenly very aware of her own body. Of how stiff she felt. Of how unfamiliar the room was.
A few of the girls recognized her immediately.
“You’re really joining us today?” one whispered, eyes wide but warm.
“I think so,” Y/N whispered back, smiling nervously.
The instructor clapped their hands, calling everyone into formation. “Today we’ll be working on basics,” they announced. “Posture, rhythm, control.”
The music started, and within minutes, sweat beaded at her hairline. Her body knew music, but not like this. Every movement required intention, strength, repetition. Her timing lagged just half a beat behind, then rushed forward to compensate.
Again.
And again.
And again.
Her legs burned. Her lungs protested. When she caught her reflection in the mirror, she saw someone trying very hard not to look like they were struggling.
You wanted this, she reminded herself. You wanted to know.
During a short break, she leaned against the wall, chest rising quickly. One of the girls handed her a bottle of water.
“You’re doing fine,” she said quietly. “First days are always like this.”
Y/N nodded, grateful. “You make it look easy.”
The girl laughed softly. “It’s not. But you will get better, trust me.”
Vocal training followed next.
This room felt more familiar. A piano in the corner. Microphones. Warm-ups that eased into her bones rather than fought against them. Y/N relaxed slightly as they worked through scales, breath control, resonance.
She wasn’t perfect. She knew that. But she could hear it, the way her voice settled when she stopped forcing it, the way her musical instincts guided her naturally.
The instructor paused after her turn. “You have good tone,” they said. “And strong musical awareness. You just need training.”
The word echoed pleasantly.
By early evening, exhaustion set in properly. Her muscles ached in places she didn’t know could ache. Her head felt heavy, thoughts blurring at the edges. When the final session ended, Y/N slipped out into the hallway, grateful for the quiet.
She leaned against the cool wall, eyes closed, letting her breath slow.
This is harder than I imagined, she thought.
And somehow… exactly what I imagined.
She opened her eyes and stared down the long corridor, lights humming softly above. A familiar doubt crept in, quiet but persistent.
Maybe this was unrealistic.
Maybe producing is enough.
Maybe wanting more is greedy.
Hongjoong stood a few steps away, hands tucked into his jacket pockets, expression calm but attentive. He didn’t seem surprised to see her there.
“Long day?” he asked gently.
She let out a tired laugh. “You have no idea.”
They walked slowly, side by side, the hallway nearly empty now.
“I’m exhausted,” she admitted. “And scared. And kind of embarrassed at how hard everything felt.”
“That’s normal,” he said. “If it felt easy, it wouldn’t mean much.”
She glanced at him. “What if I can’t keep up?”
Hongjoong turned toward her, expression serious but kind. “Then you learn,” he said simply. “No one is born knowing how to do this. Not idols. Not producers. Not anyone.”
She swallowed. “Sometimes I feel like I missed my chance.”
“You didn’t,” he said immediately. Then, softer, “You’re here. That’s not missing it.”
She looked down at her hands, fingers still slightly trembling from fatigue. “Today was the first time I didn’t feel like I was just watching from the outside.”
Hongjoong watched her carefully, something warm and thoughtful in his gaze. “That’s because you weren’t.”
They stood there for a moment, the air between them quiet, steady. Not rushed. Not heavy. Just present.
“I don’t think you should decide based on fear,” he added. “Or on what people told you years ago. Decide based on how you felt today. Even the hard parts.”
She met his eyes then, really met them. “I felt tired,” she said. “But… alive.”
His lips curved into a small smile. “That’s usually a good sign.”
Footsteps echoed again, approaching this time with purpose. A manager and two staff members stopped a respectful distance away.
“Y/N,” the manager said kindly, “thank you for joining us today. We wanted to check in.”
She straightened slightly. “Of course.”
“How did it feel?” they asked. “Training with the group. The environment.”
Y/N took a breath. She glanced at Hongjoong not for permission, just reassurance. He didn’t speak, didn’t nod. He simply looked at her, steady.
“It was difficult,” she said honestly. “Physically and mentally. I struggled.”
The staff listened carefully.
“But,” she continued, voice growing steadier, “it felt right. Even when it was hard.”
The manager smiled. “Then we’d like to ask you properly.”
“Would you like to officially join the trainee program,” they said, “and be considered as a member of the planned girl group?”
For a second, the hallway seemed to fade.
Y/N felt the weight of the day in her bones. The ache. The doubt. The quiet moments of joy. Hongjoong’s words echoed in her chest.
Decide based on how you felt.
“Yes,” she said. Clear. Certain. Happy. “I want to.”
Relief, smiles, and soft congratulations followed, but Y/N barely heard them.
Because for the first time in a long time, she wasn’t imagining a future.
She was stepping into it.
As the staff moved ahead, Hongjoong stayed back with her for a moment.
“I guess we’ll be seeing each other more often now,” he said lightly.
She smiled, still processing everything. “I guess so.”
He hesitated, then added, “I might ask for your help in the studio sometime. If that’s okay.”
Her smile grew, softer this time. “Anytime.”
But it felt like the beginning of one.
