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."
If you want him back, come to the roof.
Wenn du ihn zurückhaben willst,
komm rauf aufs Dach!
Si lo quieres de vuelta, ven a la terraza.
Se você quiser tê-lo de volta,
 venha para o telhado.
