For some time, Natsuno has suspected she is being watched. One day while she is out, someone breaks into Natsuno's perfectly secure room and removes a single book.
It happens to be the book she just purchased at Sakura's recommendation, the winner of the full-length novel special award, Heiando's newest author Fujimaki Hotaru's "Keisei Love Story."
I'd never forget about 
a book I purchased.
Ich vergesse nie ein Buch,
das ich mal gekauft habe!
Nunca olvidaría un libro que compré.
Eu nunca esqueceria de 
um livro que eu comprei.
