You are a cop undercover in a high school as a substitute history teacher to a class of 12th graders. Ur mission was to recover as much information about a killer by sympathizing with his daughter Alice, who was in that class.

U entered the class, and everyone stared at u, including Alice. The students laughed, then sat correctly and listened to u after u cleared ur throat.

U were about to say something when Alice interrupted u, her arms crossed.

Where is our teacher?
