Mafia's Little Assistant

AIN

The grand, glass-shining corridors of Jeon Enterprises were always filled with hushed whispers and absolute discipline. On his very first week, Kim Taehyung stood nervously outside the main executive office, tightly clutching his files. The manager had given him one strict, final warning: “Do not let a single soul pass through that door.” Determined to do a perfect job, Taehyung stood like a wall, completely unaware of the storm heading his way. Within minutes, the private elevator clicked open, and a sharp, handsome man in a tailored black suit stepped out, radiating an intense aura that made everyone else look down. It was Jeon Jungkook—the ruthless billionaire CEO and underground mafia leader. But as Jungkook casually walked toward his office, a clear, brave voice suddenly cut through the silence, stopping him dead in his tracks: “Excuse me, sir! You can’t go inside.”

The grand, glass-walled corridors of Jeon Enterprises were always enveloped in a suffocating silence. It wasn’t the peaceful kind of silence; it was the heavy, tense quiet that came from absolute fear and discipline. Towering over the city’s skyline, the skyscraper served as the legitimate face of an empire, but beneath the polished marble floors and high-tech security systems lay a darker reality. Every single employee sat glued to their dual monitors, their fingers flying across keyboards at a frantic pace. No one dared to look up, no one dared to chat by the water cooler, and absolutely no one dared to make a mistake.

Today was Kim Taehyung’s third day working as a junior administrative assistant at this massive conglomerate. To say he was overwhelmed would be an understatement. At twenty-three, with a heart too gentle for the corporate world and a habit of taking everything literally, Taehyung felt like a small, colorful fish trapped in an ocean full of corporate sharks.

Adjusting the collar of his neat, oversized beige sweater—which he had meticulously ironed the night before—he glanced down at the shiny new company ID card hanging around his neck. The photo on the badge showed him smiling brightly, a stark contrast to the pale, nervous faces of his coworkers. Taehyung clutched a thick stack of manila folders against his chest, trying to calm his racing heart. He just wanted to do a good job, earn his paycheck, and go home to his quiet apartment.

Suddenly, the heavy double doors at the end of the hallway burst open. Taehyung’s manager, Mr. Choi, rushed out, looking completely disheveled. His tie was crooked, and beads of sweat were visible on his forehead. He scanned the room frantically until his eyes landed on Taehyung.

“Taehyung! Thank goodness you’re here,” Mr. Choi gasped, rushing over and shoving another massive ledger into the young man’s already full arms. “Listen to me very carefully. I have just been called downstairs for an emergency audit meeting in the basement archives. It’s going to take hours, and I cannot be disturbed.”

“Oh, okay, Mr. Choi. Do you need me to take notes for you?” Taehyung asked innocently, tilting his head.

“No, no! I need you to do something far more important,” Mr. Choi whispered, his voice trembling as he looked around nervously. He pointed directly at the heavy, dark mahogany doors at the very end of the executive wing—the office belonging to the highest authority in the building. “You see those doors? You are to stand guard right outside them. I just received word that an unannounced internal inspection might happen today. My instructions are absolute: do not let a single soul pass through that door. No exceptions. If anyone tries to enter without my written clearance, you block them. Do you understand? Our jobs—our entire careers—depend on this!”

Taehyung blinked, digesting the gravity of the situation. He didn’t quite understand why an internal inspector couldn’t just wait, but he nodded firmly. “Understood, Mr. Choi. I will stand right here and make sure nobody goes inside.”

“Good. Bless you, boy,” Mr. Choi sighed, giving Taehyung a frantic pat on the shoulder before sprinting toward the service elevators.

Left alone in the quiet hallway, Taehyung took a deep breath. He marched over to the executive doors and stood directly in front of them, aligning his boots perfectly with the center seam of the double doors. He held the folders tightly against his chest like a shield. He was determined to be the perfect employee. To him, this was a test of trust, a grand mission to protect his department’s integrity.

Exactly ten minutes passed in agonizing silence. Taehyung amused himself by counting the ceiling tiles and shifting his weight from one foot to another.

Then, a sharp, distinct chime echoed through the private executive elevator wing—a lift that regular employees weren’t even allowed to look at.

The heavy steel doors slid open with a smooth, expensive hiss. From the dimly lit interior, a tall, imposing figure stepped out into the bright lights of the office floor. The moment his polished leather shoes hit the floor, the entire atmosphere of the room shifted. It was as if the temperature had dropped by ten degrees.

The man was dressed in a flawlessly tailored, midnight-black three-piece suit that accentuated his broad shoulders and commanding stature. A luxury gold watch gleamed on his wrist, and his dark hair was styled back perfectly, revealing a sharp, symmetrical jawline. Dark, designer sunglasses obscured his eyes, but his expression was set in a cold, unreadable mask. He exuded an aura of absolute power, danger, and supreme confidence.

This was Jeon Jungkook. To the public, he was the brilliant, ruthless billionaire CEO who had turned Jeon Enterprises into a global powerhouse before the age of thirty. But behind closed doors, in the shadows of the city’s criminal underworld, he was the undisputed leader of the most powerful mafia syndicate in the country. He was a man accustomed to total obedience; a man whose single glance could ruin a person’s life.

Behind him walked two towering security details, but Jungkook waved them off with a dismissive flick of his hand. He preferred to walk alone into his own domain. As he strode down the corridor, the employees on either side instantly bowed their heads, their eyes glued to their desks, barely daring to breathe until he passed.

Jungkook walked with purpose, his mind already calculating the next moves for an upcoming shipping merger. He approached his private office, his hand automatically reaching out to grab the heavy brass handle. He didn’t expect anyone to be there. He didn’t expect any obstacles.

But just as his fingers were inches away from the metal, a clear, resonant, and remarkably brave voice cut through the silence of the executive wing:

“Excuse me, sir! You can’t go inside.”

Jungkook froze. His hand remained suspended in mid-air. For a fraction of a second, he wondered if he had misheard. In his entire life, no one had ever used the words “you can’t” in his presence.

Slowly, deliberately, Jungkook lowered his hand. He turned his torso around and slid his sunglasses down the bridge of his nose, revealing a pair of piercing, obsidian eyes that had made hardened criminals beg for mercy.

Standing right in front of his door was a young man he had never seen before. The boy was wearing a soft beige sweater that looked a size too big, making him look small and entirely out of place in this cold, corporate environment. Despite the fact that the boy’s knuckles were white from clutching his folders and his knees were visibly trembling, his hazel eyes were wide, honest, and staring directly into Jungkook’s.

Jungkook tilted his head, his gaze scanning the boy from head to toe, pausing slightly at the company ID badge that read Kim Taehyung.

“What did you say?” Jungkook’s voice was a low, deep baritone, dripping with a quiet, dangerous calm.

Taehyung swallowed hard. He could feel the intense, suffocating pressure radiating from the man in front of him. This stranger felt like a living storm, but Taehyung remembered Mr. Choi’s frantic face and the strict warning about protecting the office. He couldn’t let his manager down.

Taking a small step forward to firmly block the door handle, Taehyung cleared his throat. “I said, sir, you cannot go inside. My manager, Mr. Choi, strictly instructed me that absolutely no one is allowed into the executive office right now. We are expecting an important inspection, and I cannot let anyone disturb the space. If you have an appointment, you will have to wait in the lobby until Mr. Choi returns.”

A collective, silent gasp seemed to ripple through the entire floor. Nearby employees who had caught the exchange looked horrified, some covering their mouths, fully expecting the new junior assistant to be fired—or worse—on the spot.

Jungkook stared at Taehyung. He looked at the sheer innocence on the boy’s face, the slight tremor in his lower lip, and the absolute lack of malice or recognition in his eyes. This boy genuinely had no idea who he was talking to. He was simply trying to do his job with a terrifyingly pure level of dedication.

For the first time in years, a genuine spark of amusement flared deep within Jungkook’s chest. The icy, rigid mask on his face cracked just a fraction, revealing a very faint, intrigued smile. He found it utterly fascinating. The entire world trembled at the mention of the name Jeon Jungkook, yet here was this beautiful, oblivious creature standing like a fierce little guard dog at his own office door.

Instead of calling security or raising his voice, Jungkook stepped closer, closing the distance between them until Taehyung had to tilt his head back to maintain eye contact. The scent of expensive cologne and rich leather washed over the younger man.

“Is that so?” Jungkook murmured, his dark eyes locking onto Taehyung’s. “You’re very dedicated, Kim Taehyung.”

“T-Thank you, sir. It’s my duty,” Taehyung stammered, his bravery faltering slightly under the intense, undivided attention of the stranger.

Jungkook reached out, his long fingers gently brushing against the edge of the folders Taehyung was holding, before he stepped sideways. With a swift, smooth motion, Jungkook bypassed the younger man entirely, opened the heavy mahogany door, and stepped inside his office.

Before closing the door behind him, Jungkook turned back to look at the stunned assistant one last time. “Tell Mr. Choi his inspection is complete. And stay right there, Taehyung. We will be speaking again very soon.”

The door clicked shut, leaving Taehyung standing alone in the hallway, blinking in utter confusion, completely unaware that his life had just changed forever.
