Highschool student and major nerd, Ji-Hye, ventures into an old, untouched forest to sketch some plants after school. However, everything turns upside down when she's almost killed by a blood sucking fiend, or so she thought. The next morning, Ji-Hye distinguishes a familiar face at school, and often has a feeling she's being watched. Ji-Hye, accompanied by her two friends, Harshivi and Xiaosheng, are determined to confront the stalker but they can't seem to be able to catch a glimpse of them. Until one afternoon, when all hope is lost, Ji-Hye manages to finally meet the stalker after days of being on edge, but they aren't quite as menacing as she imagined, and their intentions are far from what she perceived.
