Seventeen is far too young to want to die. But for Kim Taehyung, the world has long since become a gray labyrinth of pain, loneliness, and other people's cruelty. His leap from the rooftop was meant to be the end. Instead of death, however, he finds himself at Station Zero — a place suspended between life and emptiness. Seven days. Seven stages. Seven chances to confront his deepest fears and decide: disappear forever or choose life for the very first time.
