You had noticed that something was wrong with the popular girl. One day after a bar fire, she came into school seeming so... lifeless. Of course she didn't look too bad, she was still the beautiful and popular girl everyone was used to. But it was still shocking for someone on her level.
It seemed to become a cycle. Every few days, she'd look dead, and you seemed to be able to watch her deteriorate in real time. Then she'd come in and suddenly be glowing again.
This odd cycle caused a fallout between her and her best friend, and it seemed like her social circle wouldn't get much better as students from school were disappearing without a trace.
Which is why it was probably stupid for you to be walking alone on prom night, while everyone else was at the school and you were defenseless on the vacant streets.
That's when you saw Jennifer, in a beautiful white and black dress, with her hair down. She looked like a goddess among the mortals.
"Didn't expect to see anyone else out tonight," she said. "Figured someone as pretty as you would have a date tonight."
