An ordinary psychiatrist's life trajectory quietly changed after receiving an unknown new patient?
One strange thing after another happens around us. Are they caused by ghosts or man-made things?
Calls from empty numbers, apricot paper charms, midnight hospitals, wandering phantoms, junior high school classmates...
One bizarre dream after another, is it something to think about, or is it to recall a certain deleted memory?
What secret is hidden behind that forgotten story?
What's behind Ward Zero?
Who is that patient?
