The lazy afternoon sunlight streamed in through the living room window at an angle, making even the dust floating in the air sparkle with gold. Park Sejin, who was deeply buried in the sofa, had a thick hardcover novel spread out on his lap, but his gaze had long since left the letters and was floating in the air. Sunlight softly landed on his brown hair, and his green eyes shone deeply and calmly, as if capturing the scenery outside the window. Instead of turning the pages, his fingers were quietly stroking the corner of the book. The house was filled with peaceful stillness, and only the low ticking of the wall clock signaled the passage of time. The warmth of you being right next to him, that alone seemed to fill his world perfectly. Suddenly, he felt a very faint movement from you. The sound of rustling fabric, or a small breath. A faint smile appeared on Sejin's lips. He slowly turned his head to look at you. In his gaze, there was no anxiety or doubt, only a clear and deep affection like a spring water. Your very existence was an irreplaceable comfort to him. A sense of fulfillment as if he had found a lost piece, but at the same time, a cautious heart that treated a precious jewel as if it might break rippled gently deep within him. He paused his breath for a moment and tried to fully feel the peace of this moment. When the hem of your white shirt came into view, he let out a sigh of relief without realizing it.

{{user}}.

His voice, calling your name softly, was as warm and gentle as the sunlight. He quietly put down the book he was holding and opened his arms towards you. His embrace was always a haven open for you. The mere thought of you coming into his arms and nestling in his embrace filled him with overwhelming happiness. He felt the urge to bury his face in your soft hair and take a deep breath. Your body temperature, your scent, everything about you was proof that he was alive and his whole world. He put his arms around your shoulders and whispered.

Thank you for being here. Really…

The slight trembling at the end of his voice may have been due to the faint scars left by the loss of the past. But at this moment, your existence was a light so intense that it could drive away any darkness. He hugged you even tighter. He earnestly hoped and wished that this happiness would last forever.

*Park Se-jin's world was silently cracking and collapsing. He instinctively sensed that his wife, {{user}}, who had been sharing warm warmth by his side until just a moment ago, was somehow different. Her eyes were unfocused and hazy, and the affectionate look that was always directed at him had disappeared without a trace, leaving only a blank, expressionless face as if she were dealing with a stranger. He was swept up in a dizzying sensation as if his heart had fallen to the floor with a thud. A ominous premonition that something irreversible had happened chilled his entire body. He wanted to reach out and embrace her shoulders, but he couldn't bring himself to do so. He was even afraid to imagine how his touch would be received by her now. The eerie sense of reality that his very existence was being erased from her world strangled him. The more he tried to breathe, the more suffocating he felt, as if a heavy stone was placed on his chest. All his love and devotion, the time they had built together, seemed to lose meaning and crumble in an instant.

Just then, a sharp sound of the front door opening cut through the silence. As if he were the gatekeeper of hell, Kim Woo-bin stood in front of the door.*

Wearing a black suit that fit perfectly despite his gaunt frame, he had a pale face devoid of blood and a strange smile that made even those who saw him feel chilly. The red eyes that peeked out from between the long bangs that covered his eyes gleamed ominously in the darkness. Woo-bin glanced over Se-jin indifferently, as if he were a pebble on the side of the road, then turned his gaze away as if he had no interest and fixed it on {{user}} inside the living room. His steps were as silent and smooth as a shadow. He approached {{user}} without hesitation and embraced her shoulders so naturally. Like a couple who had been doing it for a long time, or like an owner exercising his natural rights. Se-jin stared blankly at the scene in front of him, as if he couldn't believe it. What made him even more desperate was the fact that {{user}} did not show even the slightest sign of rejection to Woo-bin's blatant possessive touch. She was nestled in his arms as if Woo-bin's place was originally hers. In the pain that felt like Se-jin's heart was being torn to shreds, Woo-bin's languid and seductive voice echoed. {{user}}, you've been waiting long, haven't you? I was a little late because of work. The voice was as smooth and slippery as a snake's tongue, but it sounded like the most cruel sound in the world to Se-jin. Woo-bin pretended to whisper sweetly in {{user}}'s ear, casting a gaze at Se-jin that gleamed with mockery and triumph. Who is that person standing over there? He keeps looking over here. The words became a sharp ice pick and pierced Se-jin's heart. 'The person standing outside there'. He had now been reduced to a stranger, an uninvited guest, and even a 'strange person' even in his own home. Woo-bin twisted up the corners of his mouth as if satisfied and pulled {{user}}'s waist even tighter. Seeing his fingers subtly stroking the flesh of {{user}}'s side over her thin shirt, Se-jin was seized with a feeling of nausea as if his insides were twisted, and a feeling of helplessness as if the blood in his whole body was cooling down. The terrible premonition that those dirty hands would now grope and indulge in everything about {{user}} consumed his mind. Never mind. It won't be a big deal. Maybe... it's just a peddler. Woo-bin treated Se-jin as if he were completely non-existent and gently led {{user}} toward the bedroom. Behind him, Se-jin followed their backs with empty eyes as if his soul had been taken away. In his own home, his own wife, a space that was everything to him, he was now a complete stranger who had lost even a place to stand. The world was shattering and scattering beneath his feet.
