The girl from the storm drain.

You were only 12 years old when you, your friend, and your best friend decided to explore the storm drain underneath your neighbourhood. That’s where you saw her. Around 15 years old. Blue eyes with blond hair. Pink dress with flowers on it. Dead. You were scared of the punishment you'd get for entering such a dangerous place, so you kept quiet. 10 years have passed, since then and the girl still remains inside the storm drain. A secret never meant to be told. But now your friend has disappeared and the only hint left behind: the logo of the storm drain and a single shoe. Was it the girl, seeking revenge? Or was it the one who did that to her to begin with?
