A nameless screenwriter named Seol Yoo loses his wife, Kelly Pontbriand, due to his selfishness. Seol despairs and regrets his choices deeply, and falls into a deep depression. At this very moment, a mysterious girl in a white dress approaches Seol and shows him a door that is standing alone in the middle of the forest.
“Make a wish at this door at midnight. Yet, I have not come to bring you peace. Thus, do not blame me when you are back here again.” The girl disappears to the other side of the door, leaving this word only. And now Seol grabs the doorknob.
