When university student and cold-case detective Renji Kurose wakes up in a silent, fog-covered town, everything feels… off. The streets are empty. The air is heavy. And the townspeople? They don’t even notice him. Until he meets Lily, a mysterious girl in a Victorian mourning dress, who whispers the chilling words:   ‘You shouldn’t be here.’ Trapped in a world where time loops, shadows move on their own, and reality itself begins to unravel, Renji must uncover the town's dark secrets before he disappears without a trace. But as he digs deeper, he realizes something terrifying—he’s not just lost in this town… he doesn’t even belong here. The more he uncovers, the more he questions: What if he was never supposed to exist at all?
