In the warm glow of the morning light, Seokjin knelt down before his son, Jung-eon, and pressed a gentle kiss upon his forehead. Jung-eon's eyes fluttered open, a sleepy smile gracing his lips.

"Good morning, Appa," he mumbled, his voice still thick with sleep.

"Good morning, my little prince," Seokjin replied, his heart swelling with love for his son. He brushed Jung-eon's hair away from his face, feeling a surge of protectiveness towards the innocent child.

As Jung-eon prepared for school, Seokjin couldn't shake off a lingering sense of unease. He felt an inexplicable chill, as if an unseen presence was lurking in the shadows. He dismissed it as a passing sensation, attributing it to the stress of running the 2seok shop and dealing with the emotional turmoil caused by Jungkook's reappearance.

After bidding farewell to Jung-eon, Seokjin headed back to the shop, his mind preoccupied with the day's tasks. Shortly after, Hoseok called, informing him that he had to leave urgently to handle an important shipment.

Seokjin found himself alone in the shop, an eerie silence enveloping him. The familiar surroundings seemed to take on a menacing aura, and the shadows danced ominously in the corners. The chill Seokjin had felt earlier intensified, sending shivers down his spine.

He tried to convince himself that it was just his imagination, the product of a heightened state of anxiety. But the feeling of being watched persisted, an icy grip tightening around his heart.

He glanced around the shop, his eyes darting from one dimly lit corner to another. The silence was broken only by the occasional creak of the floorboards beneath his feet. He felt a sudden urge to flee, to escape the suffocating atmosphere that had descended upon the shop.

But then, he heard a faint sound, a whisper that seemed to emanate from the very walls themselves. It was a cold, disembodied voice, devoid of any warmth or emotion.

"Seokjin," it whispered, the name echoing through the shop like a haunting melody.

Seokjin froze, his breath catching in his throat. His eyes widened in terror as he realized that he was not alone. The unseen presence, the source of the chill he had been feeling, had finally made itself known.

The cold, disembodied voice that whispered Seokjin's name sent a jolt of fear through his body. The voice was so familiar, a chilling echo of a past he had desperately tried to bury. His heart pounded in his chest, his breath catching in his throat as he struggled to process what he was hearing.

His mind raced, trying to identify the source of the voice. Was it Jungkook, a cruel manifestation of his betrayal? Or was it something else, something more sinister lurking in the shadows?

Seokjin knew he had to confront the voice, to uncover the truth that lay hidden behind its icy whisper. Gathering his courage, he took a step forward, his voice trembling as he called out into the darkness.

"Who are you?" he demanded, his voice echoing through the eerily silent shop.

A moment of silence followed, the tension in the air palpable. Then, the voice responded, its tone cold and devoid of emotion.

"I am the one who has been watching you, Seokjin," it whispered, its words sending shivers down Seokjin's spine. "I have been waiting for this moment, for the chance to finally confront you."

Seokjin's heart sank as he recognized the voice. It was Jungkook, but not the Jungkook he knew, the friend and partner he had once shared dreams with. This was a Jungkook consumed by darkness, a man twisted by betrayal and resentment.

"Jungkook," Seokjin said, his voice barely a whisper, "what do you want?"

Jungkook's ghostly laughter filled the shop, a chilling sound that echoed through Seokjin's soul. "I want you to pay, Seokjin," he hissed, his voice filled with venom. "I want you to suffer just as I have suffered. I want you to feel the pain of betrayal, the agony of loss."

Seokjin's eyes widened in horror. He realized that Jungkook was not just a vengeful friend; he was a dangerous man, a man capable of great harm. He had to get away, to escape the clutches of this darkness that threatened to consume him.

Likewise, he turned to flee, but a cold hand clamped down on his shoulder, spinning him around. Jungkook stood before him, his eyes burning with hatred, his expression twisted into a cruel sneer.

"You're not going anywhere, Seokjin," Jungkook spat, his voice dripping with malice. "This is where your suffering begins."

Seokjin's eyes blazed with anger as he stared at Jungkook, his heart pounding in his chest like a drum. The cold, disembodied voice had confirmed his worst fears – Jungkook was back, and he was out for revenge.

"You think you've suffered, Jungkook?" Seokjin spat, his voice trembling with emotion. "You have no idea what I've been through."

Jungkook's expression remained impassive, but a flicker of pain crossed his eyes. He knew that Seokjin had suffered as well, but he couldn't bring himself to admit it. He was too consumed by his own bitterness and resentment.

"You betrayed me, Jungkook," Seokjin continued, his voice rising with every word. "You left me and our son, Jung-eon, for nothing. You broke my heart, and you shattered our family."

Jungkook clenched his fists, his knuckles turning white. He couldn't deny Seokjin's accusations. He had betrayed Seokjin, and had caused him immense pain. But he wasn't willing to let Seokjin paint him as the villain.

"I made a mistake, Seokjin," he said, his voice low and strained. "I was young and foolish, and I didn't know what I was doing."

Seokjin scoffed, his eyes filled with disbelief. "Oh, you knew exactly what you were doing," he countered. "You chose to abandon us, to chase Jimin. And now you have the audacity to come back here and expect me to forgive you?"

Jungkook's face flushed with anger. He didn't want to hear Seokjin's accusations. He didn't want to be reminded of his past mistakes.

"I'm not asking for your forgiveness, Seokjin," he said, his voice cold and hard. "I'm just telling you that I'm not going away. I'm going to make amends for my mistakes, and I'm going to win you back."

Seokjin shook his head, his heart filled with despair. He knew that Jungkook was determined to get what he wanted, but he also knew that he couldn't let him back into his life.

"You can't unmake the past, Jungkook," he said, his voice filled with sadness. "What's done is done."

Jungkook's eyes narrowed, his gaze piercing into Seokjin's soul. "We'll see about that," he whispered, his voice filled with menace.

Seokjin's heart ached as he watched Jungkook walk away, his tall silhouette fading into the distance. He knew that this was the right decision, that he couldn't allow Jungkook back into his life, not after the pain he had caused.

But the weight of his decision pressed heavily upon him, a suffocating burden that threatened to crush him. He felt a surge of emotions, a torrent of tears streaming down his face, a mix of sadness, anger, and regret.

He had loved Jungkook once, with a love so profound that it had shattered into a million pieces when Jungkook betrayed him. Furthermore, he had spent years picking up the fragments, trying to rebuild his heart, to find a way to move on.

And now, Jungkook was back, stirring up the past, reminding him of the love he had lost, the happiness he had once known. It was a painful reminder, a cruel twist of fate.

Seokjin collapsed into a chair, his body trembling with emotion. He buried his face in his hands, his sobs echoing through the silent shop. He didn't know how long he sat there, lost in the depths of his sorrow.

Finally, he gathered his composure, wiping away his tears and taking a deep breath. He knew that he had to be strong, for himself and for Jung-eon. He couldn't afford to fall apart now, not when he had so much to fight for.

Not only that, but he stood up slowly, his determination returning. He would not let Jungkook break him again. He would find a way to move on, to build a happy life for himself and his son.

As he walked out of the shop, he cast one last glance at the fading light of the setting sun. He knew that he was leaving a part of himself behind, a part that had loved and been loved by Jungkook. But he also knew that he was taking a step forward, towards a future that was still uncertain but filled with hope.

"Why are you doing this to me, Jungkook?"
