Prologue
A sudden threatening letter made the girl panic and report the crime, suspecting that someone had been following her. The case should have ended early, but it unexpectedly involved a mysterious case five years ago. The reporter turned into a suspect, a female high school student died innocently, and anonymous threatening letters made the case more and more confusing. As secrets are discovered one by one, more and more people are involved, and this death pageant reaches its climax. The insider becomes a murderer, the victim becomes a perverted stalker, the suspect becomes an innocent person, and it goes on and on.
The original sin of human nature makes things complicated. Who is the person behind the scenes who has been providing clues? The crazy killer continued his plan, and the police's analysis was overturned again and again. All victims are willing to become perpetrators in order to hide their secrets.
The flame of desire is burning the kindness of human nature, and the twisted face is sliding with cold tears. The origin of everything - just a "lie" for the eyes of others.
Original sin is inevitable
Humanity must be maintained
