Murder on the Snowbound Express

A luxury train.
Three days of snowfall.
And a murder that feels strangely familiar.

When famous crime novelist Choi San boards the winter express, all he wants is silence, deadlines, and for his disastrously lazy editor Jung Wooyoung to stop stealing pastries from first class.

Instead, a passenger dies.

Then another.

And each murder mirrors scenes from San's unpublished manuscript.

Trapped aboard a snowbound train filled with strangers, secrets, and growing paranoia, the two are forced into a deadly investigation where everyone seems to be hiding something - including San himself.

But the more bodies appear, the more Wooyoung realizes something far more dangerous than the killer:

the way San watches him like something precious.

And somewhere between midnight corridors, unfinished drafts, quiet cups of tea, and bloodstained pages, the line between obsession and love begins to disappear.
