In my senior year of high school, a strange rumor spread around our school:
If you went to the Number Three Teaching Building at midnight and encountered a ghost, you'd get 100 extra points on the college entrance exam.
At first, no one believed it, until the top student in our grade really did encounter a red-dressed ghost and scored a perfect mark on the mock exam the next day.
The whole school went crazy. Every night, students snuck inside hoping to encounter a ghost.
Then I saw it with my own eyes: in the corridor of the teaching building late at night, the ghost smiled eerily at me
"You're next."
