Yu Nian died when he was twenty-three. When he opened his eyes again, he had gone back six years, to when he was a sophomore in high school.
But everything after his rebirth was completely different from what he remembered. He remembered there being forty-six students in his class, so why were there several unfamiliar faces? He clearly remembered that the class monitor had the best grades, but on the results sheet on the wall, someone was ranked above him. This person had never appeared in Yu Nian's memories.
That person's name was Song Cen.
Yu Nian wondered if he had some kind of mental illness. He even began to think that his rebirth was just a dream he'd had while dozing off in class.
This world was too surreal. After being reborn, he found that everything he was experiencing was completely different from what he remembered, as if... two entirely unrelated timelines had overlapped after his rebirth.
When two timelines overlap, a miracle happens to me.
