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."
You're so mean, Kazuhito-kun. 
You went and died.
Das war gemein von dir,
einfach zu sterben, Kazuhito.
Qué malo, Kazuhito-kun. Te moriste.
Você é tão mal, Kazuhito-kun.
 Você se foi. Morreu.
