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're worried about 
the stalking, don't.
Das mit den Stalkern ist schon vergessen,
Si te preocupas por los 
acosadores, olvídalo.
Se você está falando da 
perseguição, não causou.
