A hot summer afternoon during break.
A boring vacation with no school and no special plans. While searching for interesting places on her phone, Seo Yuna happened to find an old abandoned school.
The name of the place was 'Hyungryeong High School'. It was a school that had been closed for 20 years, and people had stopped visiting it since then. When Seo Yuna suggested an exploration of the abandoned school to her friends, they all readily agreed, and so the six of them headed to Hyungryeong High School together.
The school they arrived at after traveling for a long time.
Beyond the rusted iron gates, a worn-out four-story building revealed itself. The playground was overgrown with weeds, and dark classrooms were visible through broken windows.
