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."
Enough about your heart. Look this way.
Lass dein Herz in Ruhe
und dreh dich zu mir um!
Ya deja lo de tu corazón. Mira para acá.
Já chega de falar sobre coração. 
Olhe aqui.
