Ruo Meiting, the head teacher of Grade 11, has to leave for a while because she wants to return to her hometown of Nanjing to get married and have children.
Until one early morning, a boy named Ruojiujiu came to Class 11 to be the class teacher. Since then, the students in Class 11 have disappeared one by one!
Monitor Ruo Zhiyu and Chinese class representative Lan Ruohuan investigated the incident, but unexpectedly found six blood-red words written on each student's desk: See you again next time!
As the incident was investigated, a major secret was accidentally discovered. There is a black mirror in the 404 office, which can lead to hell. The students are all sealed in the mirror by Ruojiujiu!
Class leader Ruo Zhiyu found the ghost exterminator Fadayi and drove away Ruojiujiu. The former class teacher Ruo Meiting returned to class 11.
Purpose: Ruo Meiting, the head teacher of Grade 1 Grade 1, has to leave for a while because she wants to return to her hometown of Nanjing to get married and have children.
