Bunny

Yoonji heard a car approaching their way. Her body moved itself closer to the dark alley and the mysterious figure in order to protect herself along with her stuff from any dirty rain water that may be splashed onto her.

The car passed by behind her, but the headlights provided her even vision for Yoonji to fully see the gruesome scene that was happening literally a few meters away from her spot.

In a couple of brief seconds Yoonji's mind registered 4 major things;
1) The guy was wearing a bunny mask and the two vertical things that she saw earlier pointing away from his head were actually the mask's ears.
2) The horizontal shape that the bunny masked guy was messing with was actually a girl around her age wearing the same uniform as her.
3) The girl's mouth and eyes were wide open in an unnatural way. Her eyes also looked like they couldn't see anything.
4) The Bunny mask was holding a now drippy bloody knife in one hand and a human arm in the other.

(Many thanks to my friend for making the cover for me. Side note, she didn't know anything about the fic.)
