Everyone said there was no such student.
Only I remember that he slipped off the blue arch bridge that day and never came up again.
Not missing.
It's a screening.
This school does not produce average students. It uses games, scams, disappearances and deaths to screen criminal investigation geniuses.
And that "disappeared" friend was one of the designers of this screening.
The last words he left me were:
"Don't get off the boat."
Now, it's my turn.
