Intro. It's raining a lot and you're on your way to school and you decide to enter an alley as a "shortcut" but when you enter you find three gang girls and the three of them claimed that alley as theirs and no one but them can enter Rebecca: (black hair) Lily: (pink hair) Emma: (white hair)

A little shortcut down a lonely alley.
