## **AFTER 4AM**
### **Chapter 1 — Four Shadows in the Tokyo Rain | **
Tokyo at midnight transforms entirely into an elusive, enigmatic second world.
Along the endless streets, vibrant neon lights flash intensely, throwing colorful reflections over asphalt soaked by heavy rain. In the final train stations, thousands of exhausted people race against time, their hearts pounding in their chests. Headlights of luxurious sports cars cut through the downpour like predatory eyes, carving paths through the metropolis.
---
Yet, inside a dilapidated apartment on the fifth floor, the pure, chaotic laughter of four innocent boys possesses the power to erase the crushing weight of the world in a single fraction of a second. The profound emotional dependency anchoring their souls transforms the freezing space into a beautifully protective sanctuary.
"Oh my god! Guys... the ramen is burning at the bottom! It’s totally ruined!" Seo Min-jun shrieked from the cramped kitchen, his voice laced with immediate panic.
"This is entirely your fault, man!" Kang Hyun-woo chuckled lazily from the sofa, throwing a cushion directly at Min-jun’s head.
"We already know you possess absolutely no talent when it comes to cooking, Min-jun... how many times must we remind you?" Han Ji-ho murmured softly from the corner of the couch, quietly closing the worn-out textbook he had been reading.
"Just turn off the stove and let’s go out to eat at a diner tonight," Park Tae-yang grumbled, throwing the refrigerator door open only to stare blankly into the hollow emptiness. He wrinkled his nose in sheer frustration. "There is literally nothing inside this pathetic fridge except a single bottle of water!"
---
Hearing his tragic declaration, the four boys exchanged glances and burst into a synchronized, echoing laugh.
The old apartment was remarkably small. Spread across the living room floor were two worn-out mattresses. In a dark corner sat a second-hand gaming console. Scattered messily over the small coffee table were empty instant noodle packets, while damp clothes hung chaotically over wooden chairs.
But to these four boys, this space wasn't merely a roof over their heads—it was something infinitely deeper. It was a pure, chosen family.
Min-jun turned off the burner, wiping the sweat from his forehead as a soft smile graced his features. "Listen... in the future, when we finally get incredibly rich... we are going to move into a massive luxury mansion together."
Hyun-woo shifted his posture instantly, declaring dramatically, "Well, as for me, I am strictly going to find a terrifyingly wealthy husband in the future."
"You don't need a husband, man... what you desperately need to sustain your drama is a rich sugar daddy," Tae-yang joked lightly, nudging him.
"Honestly, anyone with a massive bank account works for me!" Hyun-woo retorted playfully, running his long fingers through his dark hair with a flourish.
---
But Ji-ho didn't join in on the banter. He remained entirely still, staring vacantly out the glass window pane at the lashing rain, slowly sipping from his warm coffee mug.
Sensing the silent turbulence agonizing his friend's mind, Min-jun quietly crossed the room. He sat down and leaned his head gently against Ji-ho’s shoulder. An exquisite wave of non-touch intimacy enveloped the space, grounding them in the quiet dark.
"Ji-ho... why are you so silent tonight? What is hurting you?"
"It's nothing... I’m just stressing over the upcoming college assignments."
"That is a lie," Min-jun countered softly, tilting his head to look dead into his eyes.
---
A profound look of vulnerability and hidden sadness flashed across Ji-ho’s gaze. "Min-jun... sometimes, a terrifying fear grips my chest. We are entirely ordinary, innocent guys with absolutely no background or power. I lie awake trembling, wondering if we can ever find a way to settle down and truly survive in a massive, cold city like Tokyo."
The raw honesty in his confession silenced the laughter instantly. A heavy, dark tension settled over the room, turning the space breathless. The ruthless howling of the rain outside was the only sound echoing through the stillness.
Tae-yang moved forward slowly, playfully swatting the back of Ji-ho’s head. "You absolute idiot! No matter what danger destiny throws at us, we are going to face it together. All four of us!"
Hyun-woo rushed over to the mattress, wrapping his powerful arms tightly around the three of them, pulling them into a warm, protective hug. "Even if our future turns out to be a complete failure... we are going to fail beautifully together, as a family!"
Min-jun let out a breathless chuckle, tears welling up in his eyes as he held his friends close against his chest.
But in that deeply emotional moment, the four innocent boys were completely unaware… that within a matter of days, a catastrophic twist of fate was going to flip their fragile lives completely upside down.
---
### **The Shadow of the Mafia Boss**
The following morning.
A freezing winter wind swept through the streets of Tokyo, carrying the heavy darkness of the early dawn.
Min-jun was navigating his old delivery bike through the slick roads, a massive food thermal bag strapped tightly to the back. Coming to a halt at a major intersection as the traffic signal flashed red, he raised his gloved hand to wipe away the icy rain splashing against his helmet visor.
Right then, a bulletproof, pitch-black luxury car pulled up silently right beside his bike.
---
The dark tinted glass of the rear window slid down smoothly. Sitting in the back seat, a small, innocent girl peered out into the grey dawn, her voice soft.
"Papa... look, it’s raining outside again..."
Hearing her sweet whisper, the imposing man sitting right beside her turned his head slowly to gaze out the window.
A pristine, tailored royal suit. Piercing, ice-cold eyes. And a stone-carved facial expression completely devoid of any human emotion.
He was **Renji Kurosawa**.
The omnipotent, supreme ruler of the Tokyo underground mafia. He was a monster whose mere name forced his deadliest enemies to tremble in absolute terror for their lives. The dangerous, lethal aura radiating from his body was suffocating.
---
But Min-jun, idling right next to the sedan, possessed absolutely no idea that a dangerous mafia beast was standing a mere few inches away.
The signal flashed green. Min-jun twisted his bike's accelerator, speeding off into the downpour like any ordinary delivery boy.
Yet, Renji’s sharp gaze remained locked onto the side mirror, unblinkingly tracing the silhouette of the innocent boy as he dissolved into the distance. He held him under a cold surveillance.
He couldn't even comprehend his own actions, but the absolute loneliness reflecting in the delivery boy's eyes had deeply disturbed his thoughts. In that silent breath, a dangerous, unspoken eye code was officially ignited between their worlds.
---
### **The Ruthless Executive**
Meanwhile... the penthouse floor of a towering corporate skyscraper dominating the Tokyo skyline.
Inside the vast, minimalist boardroom, the air conditioning system was blasting an ice-cold draft that froze the atmosphere.
"This pathetic excuse of a design concept you brought before me is officially completely rejected!" **Haruto Takahashi** growled, slamming a thick leather file against the mahogany table with a resounding crash.
The terrifying sound plunged the entire room into a suffocating, dead silence. The senior executives and corporate employees gaped in absolute terror, lowering their heads in complete submission.
Cold. Flawless. Ruthless. That was how the corporate world defined him. He was a CEO who bowed to no one.
---
But the moment the meeting dismissed and the room emptied, Haruto walked over to stand entirely alone before the massive glass window wall. Staring out at the brilliant Tokyo skyline, a wave of profound mental fatigue hit him, forcing him to close his eyes tight.
In this society, no matter how much limitless wealth he accumulated, or how much absolute power he wielded... when he returned to his empty mansion at night, there wasn't a single soul waiting to offer him genuine warmth.
The deep, hollow emptiness inside his chest sparked a sudden wave of silent heat.
Suddenly, the phone in his tailored coat pocket vibrated violently. A text had arrived from his personal assistant: *"Sir... the high-profile event scheduled at the luxury club tonight has been officially confirmed."*
Haruto muttered a low, detached baritone, typing back a solitary response: *"Hm."*
---
### **The Serene Healer**
Tokyo Medical Center.
Emergency sirens replayed loudly throughout the sterile hospital corridors.
"Doctor Saito! Please hurry!" a nurse shouted frantically, sprinting straight into his private cabin. "A high-risk emergency patient was just rushed through the doors! They are in critical condition!"
**Yuki Saito** didn't waste a single millisecond. He pulled on his surgical gloves with absolute, practiced precision.
In his calm eyes, there was never a shred of panic or fear, no matter how catastrophic the crisis. No matter how immense the surrounding chaos grew, his deep voice remained remarkably soft, serene, and steady.
Right as his hand touched the door of the operating theater, Yuki paused for a fleeting second, casting a silent glance out the window at the freezing rain.
He thought to himself... a doctor who spends every waking hour saving hundreds of souls standing on the edge of death... surely needs a comforting anchor to hold onto when his own heart fractures in the dark.
---
### **The Explosive Confrontation**
The Metropolitan Police Headquarters.
The walls of the Chief's office were vibrating with absolute fury.
"Park Tae-yang!" ACP **Riku Nakamura** roared, slamming his heavy fist against the desk with a force that echoed horribly through the room.
But Tae-yang didn't flinch. Placing both of his palms firmly onto the police desk, he leaned his body forward, bringing his face mere inches away from Riku's.
"Sir... you are treating that innocent suspect unfairly and illegally, simply to satisfy your old personal vengeance!"
"Mr. Tae-yang... learn to stay within your absolute limits! This isn't a chaotic street market where you can bark commands... this is a police station!"
"Oh, really, sir? Then the government should definitely award a medal to your massive, toxic ego!" Tae-yang countered, a mocking, defiant smirk playing on his lips.
---
The atmosphere inside the office instantly spiked to a lethal level of electric tension. The surrounding junior officers held their breath, frozen in absolute silence as they watched the clash.
Riku rose slowly from his executive chair, closing the remaining distance until he stood an inch away from Tae-yang’s face. He possessed exceptionally broad shoulders and a strict, commanding authority that demanded absolute obedience.
"Mr. Tae-yang... if you ever dare to display this insolent, rude behavior before my face again... I will personally arrest you and throw you into a cell this very instant. Watch yourself."
Tae-yang stared dead into his cold eyes, his smirk turning dangerous. "Then go ahead and try to arrest me right now, ACP... let's see you try!"
The raw intensity locking their eyes together sparked a fierce, dangerous current between them.
---
### **The Sacred Oath Under the Moon**
Later that night.
The four best friends sat closely together on the open rooftop of their old apartment building, letting the cool midnight breeze wash over them.
The heavy rain had finally ceased. The brilliant, multi-colored lights of the Tokyo skyline reflected beautifully within their innocent eyes.
Hyun-woo held a steaming cup of instant ramen, declaring mischieviously, "Listen... this weekend, the four of us are going to dress up and visit the most exclusive luxury club in the city!"
"We possess absolutely no money to afford the bills at a high-end club like that, man," Ji-ho countered practically.
"Do not stress over the finances, guys... tonight, I am officially treating all of you to a grand night out with my own cash!" Hyun-woo cheered, waving his hands dramatically in the air.
"Where on earth did you get enough money to cover the bills of an elite club?" Min-jun questioned suspiciously, narrowing his eyes.
"What does it matter if I don't have savings right now? I possess a breathtakingly pretty face that has the power to bring the world to its knees!" Hyun-woo bragged, playfully flipping his hair.
Tae-yang laughed out loud, grabbing a nearby cushion and violently shoving him off the mattress. "Shut your dramatic mouth, you absolute poser!"
---
For the next few minutes, the four boys fell into a comfortable silence, simply watching the glowing city lights together. The quiet bond stretching between them felt deeply safe—like a pure, unyielding family.
Min-jun stared out at the metropolis, asking in a low, thoughtful tone, "Hey... in the future, when we grow older... no matter what crushing hardships destiny throws at us, will we always stay together just like this, anchoring each other's souls?"
Ji-ho turned his head, looking at him in surprise. "Why are you suddenly asking such a deep question, Min-jun?"
"I don't know, Ji-ho... but deep within my heart, a sudden fear whispers that these pure, happy moments we share are destined to be short-lived."
Hyun-woo reached over without a second thought, firmly pinching Min-jun's cheek. "Stop overacting, you absolute drama king!"
---
Tae-yang raised his water bottle into the air like a grand chalice. "Fine... then right now, beneath this freezing midnight sky, let’s make a sacred, unbreakable promise to one another!"
Hearing his commanding tone, the other three boys turned to look at him with absolute seriousness.
"No matter what terrifying dangers we encounter in life... even if a situation demands our very lives... we will never, ever abandon one another. We will never leave each other behind!" Tae-yang declared, his voice firm.
A profound weight settled over their hearts, plunging them into a breathless silence. The cool night wind rustled their hair. Min-jun smiled gently, placing his right hand forward in the center.
"Promise."
Ji-ho didn't hesitate for a single second, placing his palm firmly over Min-jun's. Hyun-woo slid his hand over theirs. Finally, Tae-yang slammed his hand on top of the pile, establishing an ironclad fist lock.
---
Their hands were bound tightly together, locked in a fierce embrace, while Tokyo gleamed beneath them in a sea of thousands of lights.
But there was a terrifying, lethal reality that the innocent boys were completely oblivious to.
Parked a distance away from their building, shrouded completely in the pitch-black shadows of the street, sat the bulletproof luxury sedan.
Inside the dark vehicle, the predatory, piercing eyes of the mafia kingpin, Renji Kurosawa, were fixed rigidly onto the rooftop—unblinkingly locked onto Min-jun’s laughing face.
He couldn't comprehend the obsession, but ever since he had caught a glimpse of that delivery boy's radiant smile on the road this morning, the ruthless mafia boss's mind had been intensely disturbed, intoxicated by a strange attraction.
His bodyguard, sitting in the front passenger seat, asked respectfully in a low whisper, "Boss... time is running out. Shall we depart?"
Renji offered absolutely no response. He merely looked up at the sky. In that exact breath, thick, dark clouds rolled over the moon, and a heavy downpour began to lash against the city once more.
---
At the exact same time… inside an excessively luxurious seven-star hotel in the heart of the city, a grand business success gala was underway.
Haruto stood tall among the ruthless crowd of wealthy elites, clad in a pristine suit as he held a glass of fine red wine. The people around him wore perfect, counterfeit smiles. But Haruto could see right through them, detecting nothing but pure loneliness and a bottomless emptiness.
Suddenly, a pure, beautifully melodic laugh echoed from the lounge corridor just outside the grand hall.
It was Hyun-woo.
---
He was wearing a part-time catering uniform, talking and laughing innocently with the hotel kitchen staff.
Haruto’s sharp, predatory eyes instantly cut through the colorful crowd, locking directly onto Hyun-woo’s face.
The radiant, unshielded smile gracing the smaller boy's lips was breathtakingly bright. It stood in absolute, staggering opposition to the deceptive, freezing corporate universe Haruto commanded every single day.
But Hyun-woo remained completely oblivious to the fact that from the dark shadows of the corridor, a powerful corporate beast was watching his every move like a predator.
---
Inside the quiet hospital cafeteria.
Since the midnight hour had long passed, the space was entirely empty, enveloped in a serene peace.
Ji-ho stood entirely alone by the automated coffee machine, his shoulders slumped with immense fatigue. The grueling college classes, followed immediately by the suffocating work pressure of his night shift, had turned his sharp eyes completely bloodshot.
Clutching his warm paper cup, he whirled around to leave—and in that exact, hurried second, his shoulder collided violently against the broad chest of a man passing by.
The sudden force sent the cup flying from his grip, the scalding liquid about to splatter everywhere—when a long, exceptionally warm hand shot forward out of nowhere, deftly catching the cup in mid-air with absolute, fluid grace.
"Careful, Mr. Ji-ho," a remarkably soft, soothing voice murmured.
The imposing man standing before him was none other than Doctor Yuki Saito himself.
---
Stunned by the sudden physical proximity and the overwhelming Alpha aura radiating from the older man, Ji-ho’s pulse raced as he instinctively lowered his head in sheer nervousness. "Sir... I am incredibly sorry... it was entirely my fault. I wasn't looking."
Looking down at his flushed panic, Yuki let out a gentle, deeply affectionate chuckle. "You possess absolutely no reason to apologize to me, Ji-ho... besides, aren't you the exact same boy who works as a part-time cashier at that old downtown bookstore?"
Hearing his words, Ji-ho tilted his head up in absolute shock, his dark eyes wide. "Sir... how on earth do you know my name... and my job?"
"The psychological novel you personally recommended to me at the counter last week... is still resting safely on my executive desk, Ji-ho," Yuki replied softly, his gaze locking into the boy's.
At that effortless statement, Ji-ho’s pale cheeks turned a deep crimson, a strange, unsaid warmth rippling through his chest. In this cold, selfish metropolis, the realization that a powerful, elite doctor had remembered his fragile existence touched his soul deeply.
---
Out on the dark streets of Tokyo.
The torrential downpour grew increasingly violent, lashing against the concrete.
Tae-yang was navigating his high-powered sports bike through the slick roads, driving at a dangerously high speed. The freezing rain struck his face fiercely, but he refused to slow down.
Suddenly, the deafening, sharp echo of a police siren shattered the night from directly behind his bike! *Screeeech!*
"Damn it! What is this police chasing drama now?!" Tae-yang muttered in pure annoyance, slamming on his brakes to pull over to the side of the road.
An imposing, heavy tactical police bike pulled up right next to him, coming to a halt in absolute silence.
---
The rider removed his matte-black helmet, resting it on the tank. It was ACP Riku.
He stared dead into Tae-yang’s face with a pair of freezing, razor-sharp eyes. "Mr. Tae-yang... do you possess even a microscopic shred of awareness regarding the traffic regulations and speed limits of this city?"
Bowing to no authority, Tae-yang leaned his body forward over his handlebars, bringing his face dangerously close to Riku's as a defiant, mocking chuckle escaped his lips. "Sir... a serious doubt is plaguing my mind. Have you abandoned your official duties just to secretly stalk my perimeter everywhere I go?"
---
The moment that insolent remark left his lips, a look of pure, lethal danger flashed across Riku's eyes.
Without a single word, his strong hand shot forward out of pure instinct, fiercely grabbing the collar of Tae-yang’s leather jacket and violently pulling the boy toward him.
The sudden, brutal force eliminated the physical distance between them in a split second, trapping them in a breathless loop of non-touch intimacy. The freezing raindrops slid down their flushed faces, dripping into the space separating their lips.
Being held at such a lethal, close range by a powerful Alpha presence, Tae-yang’s pulse skipped a violent beat, thudding with a roaring speed against his ribs.
---
Riku stared dead into his eyes, his voice dropping to a low, gravelly whisper that carried a terrifying warning. "Do not play your smart games before my face, Mr. Tae-yang. If I ever catch you navigating these roads this dangerously again... I will personally shoot you down right where you stand. Remember that."
Releasing his iron grip on the jacket collar, Riku casually donned his helmet, fired up his engine, and roared away into the blinding rain.
Tae-yang remained completely frozen on the deserted asphalt. Placing his trembling palm over his racing chest, he stared blankly into the dark emptiness. "What on earth is wrong with that man... the sheer power in his gaze is terrifying..."
---
Past 4:00 AM.
The four best friends had returned safely to the sanctuary of their small apartment. They lay closely together on the mattresses spread across the cold floor, a classic movie playing on the small screen.
Hyun-woo was playfully tossing popcorn from a plastic bowl at everyone, breaking the quiet. Ji-ho, unable to fight the freezing draft, had buried himself completely inside a thick blanket, his eyes glued to the movie. Tae-yang sat at the edge of the sofa, quietly scrolling through his phone.
But Min-jun wasn't paying attention to the screen. He stared vacantly at the ceiling, completely submerged in a deep, silent psychological storm.
"Min-jun... what is wrong? Why do you look so serious?" Ji-ho murmured softly from beneath his blanket.
Min-jun let out a slow, bittersweet smile, his voice carrying a beautiful layer of hidden sadness. "It's nothing, Ji-ho... but for some unexplainable reason, I just thought... wouldn't it be incredible if our boring, ordinary lives faced an intense twist or a grand drama?"
---
The moment those words left his lips—Hyun-woo bolted upright on the mattress, shouting enthusiastically, "Say no more, brother! Tomorrow night, our grand appearance at the city's biggest luxury club is officially one hundred percent fixed!"
"Absolutely no way! We are not going!" the other three boys yelled back in unison, throwing cushions at him.
Sinking under the flying cushions, the four friends looked at one another and burst into a loud, harmonious laugh that echoed through the small space.
But inside that cramped cabin apartment, surrounded by the beautiful downpour of their innocent laughter… lay a terrifying, gruesome truth that the four friends were completely blind to.
The solitary club night they were planning to attend tomorrow… was destined to violently drag their lives, and the sacred bond between their souls, into a catastrophic, blood-soaked living hell.
Destiny had officially set the stage for an all-out underground war.
— To be continued.
