The Fragile Barrier
Even as her secret relationship with Lee Han deepened, Han Sujin did her best to fulfill her role at home. She prepared delicious meals for her husband, Park Taeyoung, kept the house impeccably clean, and strove to honor her responsibilities as a wife despite the chaos of her daily life.
Park Taeyoung was deeply moved by Sujin’s devotion. He felt his love for her grow, expressing his affection through small gifts and tender words. Their conversations became more frequent, and their mutual trust and love seemed to flourish.
However, their physical intimacy was slowly fading. Exhausted by an increasing workload, Park Taeyoung would often fall straight into bed at night. Even when Sujin lay beside him, he would sink into a deep, heavy sleep, leaving no room for further physical connection.
Conversely, Sujin’s body was becoming increasingly responsive to Lee Han’s touch. The secret caresses that followed their routine patrols were leaving new marks upon her. While the scent of Park Taeyoung began to fade from her skin, the sensations instilled by Lee Han began to dominate her very being.
Sujin wrestled with internal conflict as she accepted this reality. She was confused, wondering if it could ever be justified to surrender her body to Lee Han and find pleasure in it. Whenever such thoughts arose, she desperately tried to rationalize them. She told herself that all of this was a choice made for Park Taeyoung, an extension of her love for her husband.
This distorted affection slowly eroded Sujin’s heart. The deeper her relationship with Lee Han became, the deeper her self-deception grew—the belief that these acts were for the sake of her husband. Unable to find a way out of this contradictory situation, Sujin sank further into confusion.
As if it were a routine, Lee Han and Sujin headed to her home after their patrol. Sitting side by side on the sofa, Lee Han took Sujin’s hand and guided it over his trousers. She could feel his hardened member against her palm.
"I can't do this..."
Sujin tried to pull her hand away in a panic, but Lee Han would not let go.
"If we want to keep our relationship safe, shouldn't we satisfy each other's needs?"
His clever words left Sujin in a daze. After a moment of hesitation, she reached for the buckle of his trousers. Trembling, she began to slowly lower his pants.
Lee Han’s member sprang free. Sujin grasped it with shaking hands. The hot, throbbing flesh pulsed within her grip. Instinctively, she began to stroke it.
Lee Han let out a sigh and began to caress Sujin’s breasts. His fingers stimulated her nipples with persistent intensity. As the caresses deepened, Sujin couldn't help but let out a moan.
"Hnn... ah..."
Intoxicated by desire, the two explored each other’s bodies, feeling the heat of their breath. Lee Han’s hand forced its way into the most intimate part of her, stirring her violently. As the peak approached, Sujin gripped his member even tighter.
"Ugh... I'm...!"
With a powerful jolt of electricity, Sujin reached her climax. Shortly after, Lee Han followed suit. Hot semen spilled over Sujin’s hand.
Gasping for air, Sujin instinctively took his spent member into her mouth. It was an act she had repeated many times in the management office. Without a moment to think, her body had moved on its own.
Sujin was shocked by her own actions. It was the moment she realized she had reached a point of no return. Tears of misery welled up and spilled over.
"Well done, Sujin."
Lee Han stroked the hair of the sobbing woman, offering comfort. Yet, the smile lingering on his lips was closer to triumph. It was the sense of achievement that came from having made Sujin entirely his own.
Sujin buried her face in Lee Han’s chest and wept. Enveloped in the despair of having lost her way home, she could do nothing but sob. The path she had chosen for the sake of a happy family had ultimately driven her into this deep, dark abyss.
Every day at noon, Lee Han and Sujin explored each other’s bodies. Spending secret time together after patrols had become a daily routine. What began as merely feeling skin with their fingertips had evolved into satisfying their desires in deeper, more profound ways.
When Lee Han’s lips touched the nape of her neck, Sujin shivered involuntarily. Though she had initially flinched, surprised by the unfamiliar sensation, she gradually began to accept it. She found herself adapting to the kisses Lee Han would press against her neck as if it were a habit.
Before long, Lee Han’s lips moved away from her neck and traveled lower. Down to her breasts, to her navel, greedily tracing her skin. His hot breath licked at her nipples and hovered around her navel before descending toward her lower abdomen. The sensation, as if her entire body were melting, made Sujin twist her waist of her own accord.
"Hnn... right there..."
A moan, bordering on a scream, escaped Sujin’s lips. Lee Han smiled and attacked her sensitive spots even more persistently. Using his tongue to brush against the secret down and rolling his tongue over her clitoris, he began to suck at the secret crevice that was already wet with her arousal.
Sujin also strove to provide Lee Han with the same pleasure. She pulled out his member, stroking it with her hands and taking it into her mouth. Seeing Lee Han’s waist tremble, Sujin felt a strange sense of achievement.

The fire of desire burned ever brighter. Rolling on the sofa, exploring and tasting each other’s flesh had become an indispensable routine for the two. Their hands and mouths, never tiring, roamed every corner of each other’s bodies.
However, the more intense these acts became, the more Sujin drew a line in the corner of her mind. No matter how much she craved Lee Han or allowed him to touch her, she would never tolerate penetration. It was the final line she had drawn for herself, the symbol of resistance she could not allow to crumble.
Lee Han, too, did not attempt to cross that line. For now, he was satisfied just to see Sujin’s submission, and he had no intention of forcing anything more just yet. Satisfied with the pleasure exchanged through hands and mouths, he was slowly eroding Sujin’s very soul.
Sujin did not know how long this dangerous balance would last. Even as she surrendered her body to Lee Han’s touch every day, she vowed never to allow him beyond that line. Even if most of her life was becoming distorted, she wanted to protect the last shred of her pride.
Sujin bit her lip, racing toward the peak. Even as she closed her eyes and let out sighs of pleasure, only one person’s face flashed through her mind.
'Taeyoung... I'm sorry...'
Though Sujin was drowning in guilt and despair, she knew she was walking a path of no return. She simply could not imagine what awaited her at the end of that road.
Lee Han sensed that only the final stage remained in his relationship with Sujin. The moment he crossed that final line, she would be completely in his grasp. However, Lee Han had no desire to "possess" Sujin. It was enough that he could take her whenever he wished.
'How should I do it...'
Lee Han fell into deep thought. Until now, it had been threats and cajolery that moved Sujin. By gradually breaking down her boundaries, Lee Han had gotten what he wanted. But the final gate did not seem like it would open easily.
He could suppress her with physical force. But that was not Lee Han’s way. He had to make Sujin allow it and welcome it herself. Only then could it be called a true victory.
'Could it be... love?'
A sneer played on Lee Han’s lips. Capturing Sujin’s heart with clever lies might be a method, but it seemed like too much effort. He didn't need Sujin’s sincerity; he only needed her body.
Sitting at his desk, Lee Han was lost in deep contemplation. He sought a way to dig into Sujin’s weaknesses. Simple threats would not be enough to cross the final line. He had to find that fatal crack where she would have no choice but to collapse.
'Her husband? Hmm...'
Park Taeyoung was the only hope Sujin was currently clinging to. The moment that hope collapsed, Sujin might instead become a threat to Lee Han.
Lee Han bit his lip, lost in thought. Something to move Sujin’s heart. The pressure point that would force her to cast off the shackles of her body herself was, after all, Park Taeyoung.
Lights flickered on the monitor screen. Lee Han began to stare at the monitor showing Park Taeyoung and Han Sujin in the evening.
As usual, Park Taeyoung and Han Sujin were having dinner together. A happy smile filled Park Taeyoung’s face as he ate the food Sujin had prepared with such care. Yet, beyond that smile, a haggard, exhausted face was faintly visible.
"Honey, aren't you overworking yourself lately? You don't look well..."
Sujin asked cautiously. Park Taeyoung startled, then immediately flashed a smile as bright as the sun.
"No, I'm fine. This much is nothing. I'm the head of this household, after all."
Park Taeyoung spoke loudly, but there was no strength in his voice. When night fell and he lay in bed, he would, as always, fall into a deep sleep immediately. Seeing her husband barely finishing the day after dragging his exhausted body home, Sujin’s heart ached.
'It’s a relief that I at least have money coming in from this job...'
Sujin thought with a bitter smile. It seemed too much for her husband to manage the household alone. In this situation, her earning money would be a great help to their family.
At that moment, Lee Han’s face flashed through her mind. His sharp gaze and the sinister smile he wore. She remembered the lustful hands that had explored her body.
'Even if I surrender my body to that man, my heart will be yours forever...'
A strangely twisted thought reared its head. That surrendering her body to Lee Han was, in fact, for her husband’s sake. Sujin knew that such a delusion was dangerous. But for now, easing Park Taeyoung’s burden seemed like the best choice.
'Our relationship hasn't changed. My love will remain the same...'
Sujin repeated to herself. Even if many things were going wrong, she was still Park Taeyoung’s wife. She convinced herself that all this deviation and betrayal was ultimately for him.
Sujin firmly resolved in her heart that her love for Park Taeyoung would never waver. Even if it were a mask of hypocrisy, that belief felt like her final breakwater.
If it were for her husband’s happiness and the peace of their home, she could endure this dirty tightrope walk. Sujin deceived herself again and again. Even as she walked, little by little, slowly, toward the abyss.
