On the Edge of Sin

The city never sleeps at night. Streetlights flicker, reflecting off the misty pavement, and car horns blend into a meaningless symphony of a restless world. But in a quiet corner at the heart of it all—a cozy café bathed in warm yellow light—I sat, silent like the darkness within me. The cup of coffee in front of me had long gone cold, yet I kept my hands wrapped around it, as if its fading warmth could somehow soothe something deep inside. A few days ago, I killed a man. Not in a moment of rage. Not in blind anger. Every step was carefully planned—every move, every trace, every heartbeat. That man—he—deserved to die. A successful businessman in the eyes of the media, but behind the spotlight, he was a monster in human disguise. A child trafficker. I knew it too well. I had once been one of those children. Not just me—countless others, deceived, sold, locked away, their childhoods destroyed by his hands. He ran an entire trafficking ring, hidden behind charitable organizations and orphan support centers, but underneath it all was a filthy, blood-stained underworld. I carried those memories with me as I grew—sleepless nights, the feel of ropes against my wrists, the muffled screams no one ever heard. I tried to forget. But the older I got, the clearer it became—if I didn’t do something, more children would suffer just like I had. The police couldn’t help. No solid evidence, no one brave enough to testify. He had money, power, and dirty connections embedded deep within the justice system. Even the press was bought. So I acted. My plan was simple. Precise. Silent. I tracked him, memorized every habit, every vulnerability. And on a rainy night—much like this one—I broke into his luxury apartment. I used the very same tools he once used to control others: rope, and silence. He begged for his life. But I wasn’t a god. A murder that shook the city: a famous CEO—once suspected of human trafficking—found dead, blood scrawled across the wall in a single message: "Who judges the judge?" The media called it “a mysterious homicide.” No fingerprints. No witnesses. No leads. They knew nothing. And I—I felt relief. Not because I had killed him, but because I knew—at least one monster had vanished from this world. And now, I sat here. In the soft light of the old café, a place that had once been a sanctuary when I was a child running from reality. Here, I wasn’t a victim. Not quite a villain either. Just... me. And then he walked in. Yeonjun. Not a name I had ever hoped to see appear in my life—especially not now. But life doesn’t ask for permission. He walked up to the counter, ordered a black espresso—no sugar—then scanned the room before sitting at the table closest to mine. Not because the café was full. But maybe... because something about me stood out. Quiet. Cold. But not lost. I noticed the way he looked at me—observing, not intrusive. The kind of gaze belonging to someone who had seen far more than they should. I turned slightly, my voice soft. “Do you come here often?” He paused for a second, maybe surprised that I was the one to start the conversation. “Occasionally,” he replied. “When I need to think.” “Stressful job?” I asked, eyes still on my coffee. He gave a small chuckle, a flicker of interest in his eyes. “I’m a cop. A detective.” Silence passed like a ripple between us. I didn’t react like most people would—no widened eyes, no awkward fidgeting, no feigned politeness. Just a small nod. “Oh, so you must be on a case, then?” He nodded. “Is it difficult?” I asked, as if we were discussing the weather. “‘Difficult’ doesn’t even begin to cover it,” Yeonjun muttered, his eyes sharpening. “It’s a murder case. The victim was a high-profile CEO—the killer was incredibly meticulous. Not a single clear trace.” I remained perfectly calm, but inside, my heart skipped a beat. Because I knew—I was the one who committed that murder. And Yeonjun—the man sitting across from me, with eyes sharp like blades—he was the one assigned to uncover the truth. But he didn’t know. He couldn’t possibly know.
