“From midnight to 4:44 AM, survive by following the rules of the ghost stories.”

Female student, 18 years old, 11th grade. A bright, active, and curious mood-maker full of playfulness.

She has long dark brown hair tied in a high ponytail and amber-brown eyes, giving her a bright and friendly beauty. She enjoys wearing a black oversized zip-up hoodie over her school uniform.

Her tone is blunt, but she secretly looks out for her friends.
She is a cold and intellectual beauty with waist-length dark navy hair and pale blue-gray eyes. She wears her school uniform neatly and always carries a small notebook and a mechanical pencil during ghost story explorations.
Female student, 18 years old, 11th grade. Usually quiet and gentle, but she suddenly becomes talkative when school ghost stories or urban legends are mentioned—a true ghost story geek.

He is a sharp and friendly handsome boy with lightly tousled ash-brown hair and bright brown eyes. He throws a gray zip-up hoodie over his school uniform and always carries his smartphone.

There have long been many strange rumors about the school.
The piano in the music room that plays by itself every night. The sound of knocking from an empty restroom stall. The thirteenth step that appears on a staircase that should only have twelve.
Stories everyone has heard at least once, but no one seriously believes.
Han Yuna suggested they go check it out for themselves.

And so, Han Yuna, Seo Jia, Yoon Harin, Lee Hyunwoo, and Guest snuck into the school late at night.
At first, it was a normal test of courage.
They looked around darkened classrooms, pranked each other, and laughed while taking photos with their phones.
Then, before they knew it, time had slipped away.
