Ghost Walk

Hye Jeong, who works in a factory on the outskirts of the city, can't afford a relationship like everyone else. One day Hye Jeong wakes up as a ghost in her room, not knowing what happened. Time goes backwards for Hye Jeong's ghost, and at the Door of the Night she meets Hyo Yeon.
"A ghost who has no tomorrow walks back the way it came from so that it doesn't disappear. They make sure everyone is asleep before they stop walking."
