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 won't let you hurt Kazuhito-kun.
Ich lasse nicht zu,
dass du Kazuhito etwas antust!
No dejaré que lastimes a Kazuhito-kun.
Eu não vou deixar você 
machucar o Kazuhito-kun.
