A cubicle stacked with overdue reports and the stale scent of instant coffee. Kim Jaehyun, an ordinary Seoul office worker, spends his days in subway crowds and spreadsheet drudgery — no grand ambitions, no hidden powers, just a quiet, forgettable routine he has no interest in breaking. Then his vision fractures during the morning commute. Threads. Thin crimson strands stretching between lovers, yellow between colleagues, and something else coiled at the edge of his sightline: a black cord, dense as tar, wrapped around a stranger's throat.

The red ones pull lovers together. The black ones pull people into the ground. Jaehyun learns the hard way when he yanks a pedestrian out of a crosswalk seconds before a runaway truck barrels through. Fate does not appreciate interference. Every save tightens a noose around his own thread, and the frightened office worker who just wanted his lunch break is now a wanted anomaly in some ledger the universe refuses to show him. The real terror arrives the afternoon his own crimson thread finally appears — tied not to a living woman, but to a ghost with no black cord at all. What rule says love and death have to obey separate schedules?
