In the library's anteroom, they find Natsuno's stalker Fujimaki Hotaru--her classmate Osawa Hami.
She and Kazuhito had once exchanged promises--that she would become an author and he would be her first reader. Having become an author, Hami returned to see Kazuhito. "Welcome home, Kazuhito-kun."
Even though you're back, 
I still can't write.
Und auch jetzt, wo du zurück bist,
Aunque volviste, aún no puedo escribir.
Mesmo que você esteja de volta, 
eu ainda não consigo escrever.
