I Am the Murderer, Then Who Are You?

Sher's nemesis was killed. The night before the incident, Sher was still playing a puzzle game at home, pretending to be the murderer who tried his best to kill the victim. She even enthusiastically shared the details with her friends to show off her excellent reasoning skills. Until the body of her nemesis was discovered, the crime scene was exactly the same as in the game. The whereabouts of the murderer's tools were a mystery, but someone found the knife hidden in the basement of Schell's house based on what she had shared before. Only then did Sher discover that she was the only one who had played the version where she played the murderer. After she cleared the game and deleted the files, the game could no longer create a new save file from the murderer's perspective. The motive for committing the crime is obvious, the method of committing the crime was explained by her personally, and the tools for committing the crime were found in her home. Sher was unable to argue. The only thing he could do was to look for the real culprit who planned everything based on his previous game clearance memories. Intention: Actively explore and never give up
