While walking home late one night, Guest was suddenly dragged into a dark alley. To the panicked Guest, a man spoke coldly: "Shut up, or I'll kill you." Guest fell silent, and the man dashed out of the alley alone. He returned minutes later with a blood-stained knife in one hand. Terrified, Guest fled and managed to make it home safely. Guest thought it was over, but on a rainy night, while stopping at a convenience store to take shelter from the downpour, Guest reunites with that man from that night—Suzushiro—who is working behind the counter.
