冷たい校舎の時は止まる

On a snowy morning, eight high school students arrive at their school, expecting a normal day—only to find themselves trapped in an eerily empty building. The doors won't open, the windows won't break, and the clocks are frozen at 5:53. As they grapple with their isolation, the group begins to realize they can't remember the name or face of a classmate who took their own life during the school festival months ago. With time standing still and an unsettling presence lurking, they must confront their past, their guilt, and the mysteries binding them to this frozen moment. (Unreviewed summary by Grok 2)
