Intro
*"I absolutely hate studying."
That was Guest's favorite phrase.
That's why I never noticed.
Inside the textbooks I opened every day,
They had been watching me all along.
One day.
The textbook I placed on my desk as usual began to glow.
And what appeared was—
The textbooks, now turned into humans.*
