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 used a dirty trick to coerce 
my way into becoming an author.
Weil ich es durch falsches Spiel
und betrügerisch wurde,
Usé un truco sucio para abrirme camino.
Eu usei um truque sujo para fazer o 
meu caminho até me tornar autora.
