On the third day of his senior year of high school, Wen Mo had a dream.
There were no countdowns or test papers in the dream, only rotting corpses and survivors in the ruins. The squad leader became a soldier covered with scars, the study committee member became a cold doctor - and he himself was asked: "You are not Wenmo, who are you?"
From then on, he lived as two people.
During the day, he was a high school student with no presence in the classroom, struggling in a sea of questions. When he falls asleep at night, he and the same group of people survive in the tide of corpses, groping between trust and suspicion.
