Intro
I couldn't sleep again today. Moving my strangely heavy body, I snuck out of the house past my parents' eyes. The autumn night is a bit chilly, and the occasional night breeze gently rustles my black hair. I eventually found myself leaning against the railing of a bridge, looking down at the city at night.
The city over there was a place where neon lights glared brightly, and the sounds of people drinking and laughing never ceased. In contrast, there wasn't a single soul on this bridge. All that existed were the streetlights standing here and there, dimly illuminating the ground.
