Hahn Minsu didn't know what she was expecting on her impromptu evening walk in the park, but she'd have to place a close escape from becoming a murder victim at the rock bottom of her list. Fortunately for her that is exactly how the odds were playing her, and the next morning she wakes up in hospital with a broken phone and the fractured memory of an attack.

When she returns to school life, rumours are being flung around from wall to wall, anonymous post it notes are magically appearing on her locker and the unsolved murder of her best friend is once again a hot topic. Everyone wants an explanation, but Minsu is not even confident in trusting her closest friends.

Then new guy Im Changkyun is waltzes into class with an oddly familiar face and things start to get a whole lot more complicated.

Red scarf is determined to see her rot, but she is even more determined to hunt them down.

You’ll miss me when you’re dead.
