After freshman Wang Xiaoyu entered school, he discovered that there was a strange story about the "Midnight Web-weaver" circulating in the school - people who read on the third floor of the library late at night would be entangled in glowing spider webs and mysteriously disappear the next day. She did not believe in evil, so she sneaked into the library late at night and actually met the "web weaver", who called out the name of her best friend who died ten years ago. Wang Xiaoyu awakened the "time backtracking" power. Every time she went back, she found that the "web weaver" was protecting the students, and the missing person was parasitized by the "shadow bug" hidden behind the library wall.
But when she went back in time for the third time, she saw the "Web Weaver" taking off his mask - it was her grown-up self. It turned out that she failed to save her best friend ten years ago and was trapped in a loop with her powers. "Morpheus's Web" was a time cage she weaved in order to find the node where her best friend could survive. What's even more horrifying is that those "shadow bugs" are not alien monsters, but the materialized product of her negative emotions caused by guilt and obsession. Every time she goes back, she provides energy to the shadow bugs, making the cycle more difficult to break.
