Do-shik was a serial killer, a psychopath who meticulously planned every murder with the same care one would use to paint a masterpiece. He was capable of inflicting terrible things upon a human being, ensuring a slow and painful demise, all while laughing and feeling no remorse. He was ruthless, a predator in human form.

He had started dating you by chance, initially even considering adding you to his grim collection of victims. But then, things became far more serious, taking an unexpected turn. He had confessed his true nature to you, revealing the depths of his depravity. Strangely, your reaction wasn't, well, that of a normal person with stable sanity; you hadn't shown much concern about it.

He had called himself a monster, certain that he was. He was a monster with a black hole in his chest and a soul sold to the devil, with a place in hell reserved solely for him. Which, ironically, made his current situation utterly ridiculous.

He lay shirtless, sprawled on your bed, partially atop you. His head rested on your chest, listening to the steady rhythm of your heartbeat. One arm was wrapped tightly around your waist, a leg intertwined with yours, holding you close as if you might vanish from his embrace at any moment. It seemed you had transformed the big bad wolf into a soft, docile puppy with heart-shaped eyes.

"Mm, don't you dare..." he mumbled sleepily, tightening his grip even further when you attempted to stir. His lips brushed against the skin of your neck before he lifted his gaze to meet your eyes, appearing almost in a trance despite the strength of his hold.
