CHAPTER ONE: MURDERED

'AURTHOR'

T

he city lights flickered faintly in the distance, casting long shadows over the towering buildings. Sim Jaeyun stood outside the grandiose gates of his father’s mansion, the cold night air biting at his skin as he took a deep breath. His heart was still racing from the argument earlier, his father’s harsh words echoing in his mind like a broken record. The cruel taunts about his weakness, his inability to live up to the family name—it was all too much.

It had been a mistake to leave the mansion this late, he knew that. But Jaeyun couldn’t bear to stay inside those suffocating walls any longer. He needed air, space, anything that would distance him from the oppressive life his father had created. The streets were quiet as he wandered aimlessly, his feet carrying him far from the high-end neighborhood he called home. The world around him felt eerie, with the occasional flicker of a streetlamp and the distant hum of traffic filling the silence.

Lost in thought, Jaeyun found himself turning down a narrow alleyway, barely noticing how the surroundings had shifted from wealth to something darker. The buildings here were dilapidated, and the smell of damp concrete filled the air. But Jaeyun didn’t care—anything was better than the hell waiting for him back home. His steps echoed through the alley as he wrapped his arms around himself, trying to ward off the cold.

Then he heard it—a muffled sound, like the scuffle of shoes against pavement. Jaeyun froze. He wasn’t alone.

He edged forward, curiosity and fear tugging at him in equal measure. Just a few steps ahead, shrouded in darkness, he saw them—two figures standing in the alley. One of them was tall, broad-shouldered, and commanding, his silhouette bathed in shadows. The other figure was smaller, his voice low and pleading. Jaeyun couldn’t make out the words, but the desperation was clear.

Before Jaeyun could fully process what was happening, the tall figure moved. A swift, fluid motion. A flash of silver. And then, silence. The smaller man crumpled to the ground, his body motionless in a pool of darkness that Jaeyun realized was blood.

Jaeyun’s breath hitched. His body went cold with terror. He knew he needed to leave, to run, but his feet refused to move. His heart pounded in his chest, each beat like a hammer against his ribs as he stared, frozen in place. He’d just witnessed a murder.

The tall figure bent down, wiping the blade clean with a casualness that sent a shiver down Jaeyun’s spine. Then, slowly, as if sensing Jaeyun’s presence, the figure turned. Dark eyes, cold and calculating, locked onto Jaeyun’s wide, terrified gaze.

Lee Heeseung.

Even Jaeyun, sheltered as he was, knew who Heeseung was. The mafia king. The man who controlled the city’s underworld with ruthless efficiency. His name was spoken in hushed whispers, a figure of nightmares for those unlucky enough to cross his path.

Jaeyun’s legs finally responded, his instinct to flee kicking in. He turned, ready to bolt, but it was too late. A strong hand clamped down on his arm, yanking him back with ease. Heeseung’s grip was firm, unyielding, and Jaeyun knew there was no escape. He was trapped.

“Well, well, what do we have here?” Heeseung’s voice was smooth, almost amused, as if finding someone like Jaeyun in this alley was nothing more than a passing curiosity. His eyes roamed over Jaeyun, and the intensity of his gaze made Jaeyun feel like a cornered animal.

“I-I didn’t see anything,” Jaeyun stammered, his voice barely above a whisper. He tried to pull away, but Heeseung’s grip tightened.

“You’re a terrible liar,” Heeseung remarked, his tone now colder. He tugged Jaeyun closer, their faces inches apart. “You saw everything, didn’t you?”

Jaeyun swallowed hard, fear gripping him as he nodded, knowing that lying any further would be useless. “Please… I won’t tell anyone. I-I swear.”

Heeseung tilted his head, studying Jaeyun with a strange intensity. For a moment, there was silence, the only sound being Jaeyun’s ragged breathing. Then, to his surprise, Heeseung chuckled softly.

“I believe you,” Heeseung said, his voice low and dangerous. “But that doesn’t mean I’m letting you go.”

Jaeyun’s eyes widened. “W-What? But… but you said—”

“I said I believe you won’t tell anyone. I didn’t say I’d trust you. Besides…” Heeseung’s gaze darkened, and something unreadable flickered in his eyes. “I like the way you look when you’re scared.”

Jaeyun felt his blood run cold. This wasn’t just about keeping him quiet. There was something far more sinister in Heeseung’s eyes, something Jaeyun couldn’t understand. Before he could protest, Heeseung was pulling him forward, dragging him effortlessly towards the mouth of the alley.

“Where are you taking me?” Jaeyun asked, his voice barely steady as panic started to settle in.

Heeseung glanced at him, a smirk playing at the edges of his lips. “Home. My home, now.”

Jaeyun’s heart sank as he realized the gravity of his situation. There was no escaping this. Heeseung was going to keep him, and Jaeyun had no idea why or what he intended to do. All he knew was that he was now at the mercy of the mafia king, and judging by the way Heeseung looked at him, it wasn’t mercy Jaeyun could expect.
