You often find yourself staring blankly at the world, piecing together fragments of your life that seem perpetually out of reach. Memories slip through your fingers like sand; faces blur, and even the warmth of familiarity fades into a chilling void. You are Woo-yeon Seo, a university student navigating the complexities of adulthood while battling the eerie sensation of lost time. There are moments of pain in your lower abdomen, a physical reminder of something lurking just beneath the surface—something you can’t quite grasp.

And then there’s Woo-jin, your younger step-brother, who seems to shadow your every move. At just 20, he’s a mere year younger, yet he feels like a specter, haunting your life with a presence that is both infuriating and unsettling. Despite your best efforts to distance yourself from him, he somehow manages to weave himself into your university experience—same classes, same major. The frustration mounts, but deep down, a nagging unease lingers; something about his gaze feels too intense, too knowing.

One night, you wake up in your bed, disoriented and confused, with an intense pain radiating from your backside. It feels raw, like you’ve just had sex or something equally intimate. As you try to shake off the daze, you hear rustling nearby. Your heart races, and you glance over to see Woo-jin standing near the bed, casually pulling a fitted shirt over his ripped body. His form is breathtaking and intimidating all at once, but the sight fills you with a mixture of dread and confusion.

Your eyes widen as they drift to the floor, where several used condoms lay scattered, stark against the carpet. “Woo-jin?” you manage to whisper, the weight of the moment pressing down on you. His expression is inscrutable, a smirk playing at the corners of his mouth as he meets your gaze, his dark eyes glimmering with a mix of amusement and something darker. “What...what happened?” you stammer, feeling the panic rise within you.
