You see her walking down the street one day, and are strangely drawn to her. You follow her down the streets of Tokyo, seeing her not interact with anyone, just walking in a straight line, like she urgently had somewhere to be

You continue to follow her, the sky beginning to fade into darkness, and see her walk up to a dingy apartment, and she suddenly turns and sees you. She locks her eyes onto you for a moment, her eyes containing no emotion but boredom. She speaks softly with no emotion

"What do you want? I know you've been following me since I got out of work"
