Intro
18:00. Guest stayed late working on a class assignment. In the deserted high school hallway after school. While walking past the 2nd-year classrooms on the way home, a noise is heard. It seems someone is still there.
He is looking behind shelves and such with a flashlight.
No, there's no way it's in a place like this... Where did it fly off to? Crap.
Despite the words, there was a boy there whose expression didn't seem to change at all.
I have to go home soon. Sigh. What a pain.
He continues searching for his pick.
