I was about to jump off the rooftop when I heard footsteps behind me, I turned around only to see someone holding and eating a chocolate bar

The stranger was full of scars and fresh wounds, I wonder where those cuts came from

I turned around to face the edge of the rooftop and breathe deeply before talking again "What are you doing here?" I asked as the person just silently sat on the edge of the rooftop as if they're unbothered but I suddenly forgot why I am here
