Reporting for Duty.
Fire lieutenant!Kim Minseok x kindergarten teacher! reader.
sumary; Minseok thought a Friday morning community outreach event at a kindergarten would be quiet... and maybe painfully boring. What he didn't know was that JongIn had moved heaven and earth to get him assigned there for one very specific reason: to meet the most beautiful and undeniably bold teacher he'd ever come across. Between an oversized firefighter uniform that leaves absolutely no room for personal space, Sehun's relentless teasing, a kitten stranded in a tree, and a single wink that nearly makes Lieutenant Kim forget every protocol he's sworn to follow, what begins as a simple school demonstration quickly turns into a strictly confidential report... One that somehow ends up in his private messages instead.
The station clock hadn't even hit 7:30 in the morning when Sehun dropped his forehead onto the stainless steel kitchen table with a dramatic groan. He was already wearing the navy uniform pants and the station's gray T-shirt, the fabric stretched snugly across his broad shoulders. He looked like a man who had just been sentenced.
—Tell me this is a joke—he mumbled into the cold metal. —Please tell me I'm scheduled for hydrant inspections in the business district... or cleaning hoses all week. Hell, I'd even wash the truck twice. Just don't make me go there.
Across from him, Minseok had been carefully adjusting the straps on his boots until they were perfectly even. He didn't so much as blink before getting to his feet. As always, his uniform was immaculate, not a single wrinkle in sight, making him the complete opposite of the disaster slumped across the table.
—It's community outreach, Sehun. It's part of the job.—He picked up his jacket from the back of the chair. —Besides, JongIn insisted that the two of us handle this demonstration personally—Minseok replied in his usual calm, unwavering tone, the kind that made it clear there would be no arguing. —So get moving. I'm not showing up late.
That was all Sehun needed to hear.
He sat up so fast it was almost comical, a slow, wicked grin spreading across his face.
¿JongIn had insisted?
Sehun knew exactly why JongIn had pulled every string he could to get them assigned to this visit when the station had already completed its annual outreach quota. A knowing smile tugged at his lips. JongIn had planned this. And he'd done it so smoothly that it was almost beautiful.
Minseok had absolutely no idea what was waiting for him.
But now that Sehun knew JongIn had orchestrated the whole thing, he was more than ready to become the world's most entertained spectator... and its biggest instigator.
When Central Station's massive red fire engine rolled into the kindergarten playground with the slow confidence of a giant, Minseok and his partner expected the usual explosion of excited children.
Instead, both of them paused.
About thirty five-year-olds sat neatly on the grass in perfect rows.
And there she was.
A pair of sunglasses rested on top of her head while she held a clipboard as though she ruled the entire playground. She looked completely relaxed, completely in control.
When the engine shut off and the truck doors opened, none of the children ran toward the firefighters.
No shouting.
No chaos.
With nothing more than a subtle gesture from her, every child stayed exactly where they were, greeting the firefighters together in perfect unison.
Minseok stepped down from the truck, his heavy boots echoing against the pavement. The uniform looked unfairly good on him. The thick-duty pants and dark station shirt fit comfortably over his broad shoulders.
He barely managed two steps before something strange twisted in his chest.
The closer he got, the faster his heartbeat became.
JongIn... you bastard.
He'd been right. The teacher was stunning.
—Good morning, ma'am —Minseok greeted, forcing himself back into firefighter mode. He removed his cap in one smooth motion, revealing sharp feline eyes.—I'm Lieutenant Kim. We're ready to begin the demonstration whenever you'd like.
She greeted him with a sideways smile, letting her eyes travel discreetly over his impressive frame before meeting his gaze again with unmistakable playfulness
—Good morning, Lieutenant. Welcome.—Her voice was soft. —Firefighter JongIn told me quite a bit about your station... although he somehow forgot to mention Central was sending their finest.
Her tone remained perfectly professional for a schoolyard, but there was an unmistakable warmth behind it that caught Minseok completely off guard.
He blinked. Twice.
Behind him, Sehun quietly snorted.
The tips of Minseok's ears had already started turning pink.
She turned back to the children, introducing Lieutenant Kim and Firefighter Oh before the demonstration officially began.
Soon, the playground filled with excited laughter.
Rather than simply answering questions, Minseok had Sehun introduce the children to the equipment on the truck.
While Sehun helped several kids hold the heavy fire hose, Minseok carefully helped them try on one of the oversized structural firefighting coats they wore during actual fires.
The jackets swallowed the children whole.
Their helmets bounced over their eyes.
She moved effortlessly around the group, snapping photos with her phone.
At one point, she aimed the camera directly at the lieutenant.
Minseok was kneeling in front of one little boy, adjusting the oversized gear.
Hearing the familiar sound of the camera shutter, he looked up.
She held his gaze.
Then, to his complete surprise, she lowered the sunglasses covering her eyes with a single finger... and winked.
Minseok became so flustered that the glove he'd just picked up slipped straight out of his hands and landed on the ground with a dull thump.
Watching his lieutenant awkwardly scramble to retrieve it, Sehun had to clear his throat to stop himself from bursting into laughter.
Seeing his lieutenant's obvious fluster, Sehun adjusted the cap on his head and flashed the children the kind of smile that, to anyone who knew him, gave away exactly how much fun he was having.
—Alright, alright, hold on!—. Sehun called, raising his voice just enough to get everyone's attention—. We've already seen how adorable the kids look in the gear... But we're forgetting someone very important. Who thinks the teacher should try on Lieutenant Kim's jacket too?.
The response was immediate.
—Yeeees!—the children shouted in unison.
—Teacher! Put it on!— a pair of twins sitting right in front of Minseok chanted excitedly, clapping their hands.
She laughed, and Minseok felt another knot tighten in his stomach.
Ever since he'd stepped off the truck that morning, he hadn't been able to keep his eyes off her for very long. There was something about the effortless way she moved around the children, how naturally she shifted from keeping thirty five-year-olds perfectly organized to laughing right alongside them, that completely unraveled him.
And then there was the way she smiled at him.
As if they'd known each other for years.
He honestly couldn't remember the last time someone had managed to make him this nervous.
He watched her fold her arms and shoot Sehun a challenging look.
Then she turned back to him.
The sight alone froze him where he stood, the glove he'd finally recovered still hanging loosely between his fingers as he silently debated whether or not he should strangle Sehun later.
—Well, Lieutenant Kim—she said in a light, playful tone as she took two slow steps toward him, while he remained kneeling beside a few of the children—. Looks like we've got a very demanding audience today.
She stopped in front of him.
—Do you think a girl like me could handle your uniform?
Minseok swallowed.
At that moment, he genuinely couldn't tell whether she'd made a perfectly innocent comment or whether she'd just delivered the boldest line he'd heard all morning.
Unfortunately for him, he wasn't sure which possibility made him more nervous.
He cast a quick glance around.
The children had already gone back to giving Sehun and the fire engine their full attention.
Thank goodness.
Minseok slowly got to his feet, forcing himself to offer her a professional smile, though the sparkle in his feline eyes betrayed him. It took him a second longer than usual to answer.
—It's... fairly heavy gear, ma'am.—He cleared his throat—.But if you're willing... I don't see why not.
He paused.
For a split second, he wondered if his own response had accidentally sounded just as suggestive.
Recovering quickly, he looked toward his partner.
—Sehun, hold her clipboard.
That immediately caught Sehun's attention.
Still wearing the most insufferably entertained grin imaginable, he walked over while the children eagerly followed behind him.
Minseok picked up the massive turnout coat resting on the hood of the truck.
She handed her phone and the clipboard to Sehun.
Then Minseok stepped closer.
Much closer.
Standing only inches behind her, he lifted the heavy coat, surrounding her in his space before carefully settling it over her shoulders.
The oversized jacket fell around her body with surprising weight.
Lieutenant Kim was now standing only a few inches behind her.
She caught the clean scent of his cologne as it blended with the rough smell of firefighter gear, worn leather gloves, and smoke that seemed permanently woven into the fabric.
For the first time since she'd started teasing him that morning she had to remind herself they were standing in front of thirty small children.
—Slide your arms through—Minseok murmured.
His deep voice sounded right beside her ear.
Low.
Quiet.
Meant only for her.
Behind them, the children continued playing with Sehun, blissfully unaware.
She slipped her arms into the oversized sleeves.
The coat completely swallowed her, its weight forcing her shoulders back ever so slightly.
There wasn't much room between them.
As Minseok adjusted the coat over her shoulders, the front of his chest barely brushed against her back.
She felt herself freeze.
Before she could react, he had already stepped around to stand in front of her.
His large, practiced hands moved to the front of the coat, fastening each heavy metal clasp one by one.
There was barely any space left between them.
Every time he secured another buckle, his fingertips accidentally brushed the fabric stretched across her chest.
Minseok stubbornly kept his eyes fixed on his own hands, concentrating with everything he had on hiding the slight tremor in his fingers.
His breathing, however, had grown noticeably uneven.
The tension in his jaw was impossible to miss.
She noticed.
Realizing just how focused he was on fastening the coat, she leaned forward ever so slightly...
Closing the distance even more.
—You know, Lieutenant—she whispered, carefully lowering her voice so it wouldn't carry beyond the space between them. —JongIn talked about your station quite a bit before we scheduled today's visit.
Minseok continued fastening another clasp.
—But now that I've seen you in person—she went on softly—. I have to say he didn't do you justice.
His fingers stopped instantly.
Right on the final clasp near her collar.
His head snapped up.
His eyes widened.
Every trace of composure he'd been clinging to disappeared in an instant.
The faint blush that had only reached the tips of his ears spread across his cheeks then all the way down his neck.
For a long second, he simply stared at her. Speechless.
His hands remained frozen just below her collarbone while she met his gaze with that same fearless spark dancing in her eyes.
—P-Professor...—was all he managed before his voice cracked. He immediately cleared his throat, making one desperate attempt to regain what little dignity he had left.
From atop the fire truck, Sehun burst into loud, unrestrained laughter.
—Careful, Lieutenant!—he shouted. —You forgot the helmet!
The spell broke.
Moving far quicker than necessary, though still slightly clumsy, Minseok grabbed the heavy black helmet.
—Please tilt your head forward—he said quietly, trying to reclaim every ounce of professionalism he still had left as he carefully lowered it onto her head. The oversized helmet slipped down nearly to her eyebrows, forcing her to lift her chin with an amused smile.
Minseok simply stared. She looked tiny inside his turnout gear. Completely swallowed by the oversized coat.
And somehow... Incredibly powerful.
He was beginning to have a very difficult time remembering that he was technically still on duty.
Just as Minseok was about to answer her challenge, finally setting his shyness aside, the moment was shattered. One of the little girls came running across the playground as fast as her tiny legs could carry her.
—Teacher!—she cried.—Mrs. Molly's gray kitty climbed way up the tree and it's crying!.
The teacher immediately looked toward the fence at the back of the playground. Sure enough, a tiny gray ball of fur clung desperately to the trunk several meters above the ground.
Sehun stepped forward without missing a beat. Handing her phone back to her, he gave Minseok an exaggerated pat on the back.
—Well, looks like we got lucky—he announced with a grin.—Lieutenant Kim isn't just our captain. Rescuing cats is basically his Friday specialty.—He turned toward his superior with the most innocent smile he could fake.—Isn't that right, Lieutenant?
She raised an eyebrow.
Despite the weight of the turnout coat, she took a small step closer until she was once again standing near enough for Minseok to feel the warmth of her presence.
—Oh—she said, her smile growing just a little more playful as her eyes slowly traveled over him from head to toe.—Your specialty?—She tilted her head.—I certainly hope you don't disappoint me up there, Lieutenant.
Minseok swallowed.
Between her subtle teasing and Sehun's painfully obvious setup, he felt completely cornered.
Still... His pride as a firefighter, and perhaps an even stronger desire to impress her, won the battle.
—Don't worry, Professor —he replied. This time his voice came out steady, and the competitive spark returned to his feline eyes.— Sehun.—He never looked away from her.—Bring me the extension ladder.
—Yes, sir—Sehun answered far too cheerfully. Within moments everything was ready. Minseok climbed the ladder one rung at a time.
The late morning breeze ruffled his dark hair, and the station shirt stretched across his broad shoulders with every controlled movement upward. Whatever nerves she'd managed to stir in him only moments ago disappeared the instant he started climbing.
Up there He was completely in his element.
Every movement was precise. Graceful.
Confident.
Almost feline.
When he finally reached the frightened cat, his voice softened into something surprisingly gentle.
—It's okay—The little gray cat protested with a nervous meow and tried to retreat even farther along the branch.—I've got you.
Slowly, patiently, he reached forward until the tiny animal finally allowed itself to be gathered beneath his arm. Only then did he begin his descent.
The moment his boots touched solid ground again, the playground exploded into cheers.
The children clapped, shouted, and bounced excitedly around him. Minseok walked straight toward her.
Without saying a word, he carefully placed the little gray cat into her waiting arms. As she accepted it, her fingers deliberately brushed against his bare knuckles.
The touch lasted only a second. Even so Minseok instinctively held his breath.
His dark eyes met hers with unmistakable intensity.
—Here you are, Professor—he murmured, his voice nearly an octave lower than before. The tips of his ears were now completely red.—I hope today's demonstration lived up to expectations.
This time He took a risk. A tiny, almost hesitant wink accompanied the end of the sentence.
She blinked in surprise before smiling.
—Thank you, Lieutenant.—Holding the cat securely against her chest, she met his gaze without looking away.—That was an absolutely heroic rescue.
From the back of the truck, Sehun's lazy, teasing voice cut through the moment.
—Professor, for safety reasons and official department protocol—he called dramatically—. I think you should give the Lieutenant your phone number.—He paused just long enough to make sure everyone was listening.— You know... so he can file the confidential rescue report.—Another beat.— Or... just in case you ever need a firefighter to calm your nerves after another life-threatening kitten emergency.
She laughed openly.
The warm sound instantly shattered the composed atmosphere Minseok had been trying so hard to rebuild. She looked back at him, silently trying to figure out whether he actually wanted that.
Judging by the smile he was no longer making any effort to hide, the answer seemed obvious.
—Well—Minseok began, rubbing the back of his neck with uncharacteristic awkwardness.— I could... send you the educational material we covered with the children today.—He hesitated.—And... if it wouldn't be too much trouble—His eyes briefly flickered toward the phone she was holding.—I was wondering if you might be willing to share some of the pictures you took.
She smiled knowingly.
—I suppose that doesn't leave me much room to say no.—After a brief pause, she added—. After all... it would be a shame not to send you photographic evidence of your heroic rescue, Lieutenant.
She held his gaze just a little longer.
—Go ahead.—She recited her number slowly enough for him to type it into his phone.—But make sure that report stays strictly within your private chat.
A crooked smile finally appeared on Minseok's face. The tension melted from his jaw, replaced by equal parts relief and quiet confidence. His thumb hovered over the newly saved contact before he slipped his phone back into his pocket.
—I'll make sure to review that report... very carefully.
