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."
You're the one who left 
that book in my apartment.
Du warst es also, der das Buch
in meine Wohnung gestellt hat?
Tú eres el que dejó ese 
libro en mi departamento.
Foi você que deixou o livro 
no meu apartamento.
