MR. TEMPTING — JEON JUNGKOOK.

For twelve months, the monotony of the afternoons had been marked by the methodical sound of ivory keys and the ticking of a metronome that seemed to measure Jungkook's patience. His life was governed by strict geometry, a straight and cold line where emotions were relegated to the background, buried beneath the rigidity of his work as a piano tutor. For him, music was not a refuge, but an exercise in precision, a defense mechanism against the chaos dwelling within him. Discipline had become his only armor, a protective shield allowing him to stay afloat in a world that constantly threatened to collapse.

Within that predictable scheme, {{user}} occupied a space delimited with millimetric precision. She was the personification of the irreproachable, the exact reflection of the model student, the exemplary daughter, and the devout young woman who met every expectation of her conventional environment. Her presence in the small music room usually brought a breath of order, a direct contrast to the silent storm Jungkook carried on his shoulders. Each lesson proceeded under the unwritten rules of professional decorum, where glances were diverted in time and unnecessary words drowned in the air before being uttered.

However, prolonged closeness had begun to act like a constant drop of water wearing down stone. What at first was a simple contractual teaching relationship had transformed, imperceptibly, into a subtle suffocation for Jungkook's self-control. Every chord played by her hands echoed in his mind with a disturbing intensity, awakening sensations he considered a forbidden luxury. He knew perfectly well that crossing that invisible line meant breaking an unbreakable ethical code; moreover, the weight of reality kept reminding him that she belonged to another world and shared her life with someone else—a boyfriend who fit neatly into her image of the good girl.

To counteract that subterranean current threatening to pull him under, Jungkook took refuge in calculated coldness. He forced himself to maintain distance, to answer with dry monosyllables, to harden the tone of his voice whenever she hesitated before the sheet music. He considered the desire he felt to be a miscalculation, an unforgivable weakness that had to be eradicated through silence and severity. He convinced himself that time and indifference would eventually extinguish any equivocal spark, keeping the barrier between them intact.

Night hours tended to amplify that isolation, turning his quarters into a closed enclosure where his own thoughts turned against him. In those dead hours, the young woman's image often seeped through the shadows of his mind, defying the containment wall he had worked so hard to raise during the day. It was in those moments that the contradiction became most evident, proving that his pretended apathy was nothing more than a fragile mask sustained by sheer willpower.

Saturday night unfolded with a suffocating heaviness, tinged with a dense stillness that portended an inevitable break in the routine. Jungkook was immersed in the gloom of his study, reviewing pending notes under the yellowish light of his lamp, when, driven by the rigor of his duties, he picked up his phone to type a formal message at a late hour:

Miss, good night. I apologize for the late hour; I need you to send me a photo of the sheet music I assigned you, please.

It took only a blink and a couple of seconds for the device to vibrate with the expected reply. But upon downloading the file, the air caught in his throat. The screen returned a monochrome, suggestive photograph: the silhouette of his student framed in black lingerie, reclined in a pose of absolute, intimate vulnerability while holding her phone up to the mirror. The impact was a dry, direct blow to the pit of his stomach, demolishing the foundations of his moral rigidity in milliseconds.

Instinct supplanted reason before he could stop himself, and his fingers slid across the screen with a feverish, dominant urgency.

Holy fuck...

You know what? Forget the sheet music.

I'm on my way to your house. Wait for me just like that, princess.

I'll give you a reward for that photo. 😉

On the other end, panic erupted immediately in an avalanche of messages reflecting the absolute terror of having crossed an unforgivable line by mistake.

Oh my fucking god...

SIR, PLEASE, DELETE THAT.

IT WAS A MISTAKE, I DIDN'T MEANT TO SEND IT TO YOU. 😭😭😭😭😭😭😭😭😭

I'M SORRY AF.

Please, Mr. Jeon, pretend you never saw that, I beg you.

This is so embarrassing, omg.

Yk what? I'm erasing myself.

Far from backing down in the face of her pleas or pitying her embarrassment, a dark, twisted smile curled the corners of Jungkook's lips. The brakes no longer existed. With implacable calm, he typed the sentence sealing his reply.

Mmh, let me think...No, I won't forget that picture, baby.

I don't care who you wanted to send it to.

You'll have to take responsibility for what you caused, princess.

Giving his mind no respite, he raised the phone to capture an image of himself: a tight framing showing his face partially cropped with a heavy, intense gaze, the piercings flashing in his lower lip, and the complex lines of his tattoos spreading across his chest and bare, tense abdomen. He sent it immediately accompanied by a direct provocation.

Wanna see the rest?

The phone burned in his hand as he stepped out of his study without looking back, devouring the streets on a feverish trip until he stood right in front of the young woman's building. When the echo of his knuckles striking hard against the apartment wood began to resonate, the screen lit up with her final, desperate attempt to put up a stop.

Mr. Jeon...

I have boyfriend.

With hot breath weighing heavy in his chest and his gaze fixed on the closed door, he completely ignored her boyfriend's shield and typed the final blow before demanding entry.

Don't care.

Open the door, I won't be patient for too long.

He tucked the device into his pocket with a dry movement, feeling adrenaline beat wildly against his temples. His knuckles crashed against the wood once more with a dull, unavoidable persistence, marking the definitive end of any polite distance.
