Teacher's Pet

After witnessing a murder or discover a dead body, the student will run to their teacher and tell them that they found a "student with horrible injuries. I think they're dead." The teacher will demand that the student leads them to where the student was killed. If yandere-chan hides the corpse, the teacher will think it is a prank and scold their student. However, if yandere-chan leaves the body there, then the teacher will call the police and guard the student's corpse.
