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'm sorry. I'm sorry for 
getting your hopes up.
Verzeihung, dass ich deine Erwartungen
nicht erfülle, es tut mir leid.
Lo siento. Lamento haberte dado esperanzas.
Sinto muito. Sinto muito 
por te dar esperanças.
