An ordinary suicide case ten years ago was uncovered by someone who was unwilling to do so ten years later.
A scene full of doubts, a body that disappeared out of thin air during the investigation, a mysterious boy in white captured by the police camera, and a suicide note covered in someone else's blood.
All the facts that had been hastily covered up in the past were revealed bit by bit in the daytime.
A down-and-out uncle who is determined to find his true self, a male high school student who is innocently involved, an overly enthusiastic police officer, a strange detective who intervenes in the middle, and a mysterious and treacherous flower shop owner who cannot tell the difference between good and evil...
People who have nothing in common are pulled together because of a case ten years ago, and more and more terrifying things are discovered during the investigation...
"Don't trust anyone you can see, don't listen to anything you can hear, because you can no longer tell whether it is what you should see or hear."
"This is all just your imagination. You don't exist."
"Stop looking for it, you'll die."
"Lies used to cover up the truth are often more convincing than the truth."
"You're already dead."
"Come to me."
"It's always behind you."
