Dad Ran Away and I Became an NPC in a Strange World.

Jia Ying accidentally became an NPC teacher in a strange world. She went to the strange world to be a rules teacher and taught a group of nameless "students" to obey order. The pocket watch is a teaching aid, the badge is a work badge, and student satisfaction actually affects her real-life KPI. I thought it was just a daily routine working two jobs, until the boundary between reality and the weird world began to collapse. . .
