Adrian fell into infinite panic because he killed someone.
Suddenly, a man appeared and told him that as long as he did as he said, he would be relieved of his identity as a murderer.
Adrian, who was dubious, finally decided to believe this man.
As he solved each mystery, Adrian also embarked on a path of no return.
(The original inspiration came from the French short story "The Tuner", so I decided to use the name of the protagonist in it - Adrian)
