When the death nursery rhyme "One, Two, Three Wooden Man" rang out in the classroom, Su Xiaoxiao became a walking container of rules. Qin Xiao, whose mecha was damaged, put on nano glasses and guarded the girl with the terrifying and strange stories sealed in her body on the campus where the puppet was lurking.

When their best friend returns, neither of them know that there is something more terrifying than any monster sleeping inside her.
