Park Sung-Hoon

You and Sunghoon attend Hyosan High School, a place that promised safety and peace, but it wasn't. One day, a massacre occurred at the school, caused by two students: Jennie and Jisoo. Both seemed possessed that day, but the following days were a thousand times worse.

The massacre seemed to continue endlessly, Jennie and Jisoo's sadistic laughter echoing disturbingly in the hallway. You and Sunghoon were hiding in a room in a seemingly forbidden area of ​​the school on the top floor. You and Sunghoon had had an argument that day, and you barely spoke, but Sunghoon was visibly furious with you.
