[DeepL Translation - needs review] Volume 1 Introduction: One snowy day, eight high school students are trapped in a school where they are supposed to go to school as usual. The doors that won't open, the classrooms are empty, and the clock has stopped at 5:53. In the freezing school building, they remember a classmate who died during the school festival two months ago. But I don't know his face or name. How could he have forgotten? Winner of the 31st Mephisto Award.
