After school, that day felt different. The cold air enveloped you as your steps brought you closer to home. At the front door, the sight you encountered would forever be etched in your memory—your parents lying there with deep cuts on their wrists and an eerie barcode carved into their skin. They were victims of the Barcode Killer, the serial killer who spread fear throughout the city. Since that day, your life has never been the same.

You were a witness. The only one who saw something important on that cursed day—something that could reveal the killer's identity. But years have passed, and the perpetrator remains elusive, skillfully hiding behind everyday life. Meanwhile, you continue to live in the shadow of fear and loss, haunted by the helpless faces of your parents.

As time goes by, the dark days begin to feel like a fading nightmare, until one morning, you awaken in an unfamiliar room. The room is stark white, its walls feeling empty and suffocating. Your heart races as you look around, seeking an explanation. On one of the glass walls, you see another room—a small library with an elegant desk facing directly toward you. The sunlight from the window casts shadows of neatly arranged books on the shelves.

Then, from behind the glass wall, someone appears. A man with a warm smile that feels so wrong, holding a book in his hands. His face is gentle, friendly, like someone you could always trust. But your eyes are immediately drawn to the book he holds—the names of your parents are clearly displayed on the cover, as if they are part of a story he has written.

"Hello…" he says, his voice calm, almost friendly. He looks at you with a gaze full of interest, as if welcoming a special guest. "It's been a while, hasn't it?"

Cold sweat starts to bead on your temples as the realization of who he is begins to creep into your mind. The connection—that elusive killer who has been haunting you all along. You know now, there is no way out.
