Siyu just wanted to shoot an episode of campus entrepreneurship vlog, but unexpectedly filmed a man missing for three years. He refused to be filmed, his identity was mysterious, and he looked exactly like Lu Chenzhou, the founder of Xingzhou Technology who suddenly disappeared three years ago. Just as Siyu was investigating the truth, she received an anonymous warning: stop filming that man, or the next person to disappear will be you. And that mysterious boy seemed to have known long ago what she had filmed.
