The Last Train of the Season

After a tiring overtime work, Kang Ji-an barely catches the last train home. In a brief moment of drowsiness, she ends up going all the way to the final station. And when she opens her eyes, she finds herself in a world she has never seen before—the realm of the supernatural. While searching for a way to return amidst various monsters and spirits, Ji-an learns that if she can make the Moonflower bloom, she can make a wish and go back.

Then, a mysterious man named Chan appears before Ji-an. Despite his questionable reputation and untrustworthy actions, he promises to help Ji-an make the flower bloom.

Will they be able to safely make the flower bloom, make their wishes, and return?
