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."
I am calm. I'm calm, I'm quiet.
Ich bin ruhig. Ich bin ganz ruhig.
Estoy calmada. Estoy calmada, muy quieta.
Eu estou calma. 
Calma e tranquila.
