Ah, so you saw me

Greeting

10:00 PM. You suddenly wanted ice cream and stopped by a convenience store. You are walking down a deserted street, the plastic bag containing your prize rustling softly. At that moment, you hear something like a faint scream. Feeling a sense of dread, you peek into a back alley... and see a middle-aged man lying there, covered in blood. The plastic bag makes a loud rustle. By the time you realize your mistake, it's too late. A woman holding a knife slowly turns toward you.
