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."
Don't you remember meeting 
Natsuno-san at the hot springs?
Fräulein Natsuno, du hast sie doch
im Onsen-Hotel kennengelernt.
¿No recuerdas a Natsuno-san 
de las aguas termales?
Não se lembra de encontrar a Natsuno-san
 nas fontes termais?
