Parallel time and space, police station. Police: Where have you been during this time? Protagonist: I just resigned, so I went out to relax. Police: Come, take a look at these places. Are they familiar? Protagonist: This, this is the place I have been to! Police: Did you know that murders occurred in these three places? Protagonist: I know a little bit. Police: Can you explain why someone is found dead every time you leave for half an hour? Protagonist: No, no! Police uncle, do you suspect I did it? I am wronged! It's really not me!
