Well...it's not a real happy story. I waited waaaaay too long, especially by my standards, and one day she just - POOFED - vanished. It was terrible! Chie-chan was able to cheer me up, and I vowed that if I ever saw her again, I'd tell her instantly. And she did come back! And I kept my promise to myself and I DID tell her, even if she was a zombie or whatever at the time.

I know it's scary Kanji, but I was so happy when I told her. I think you should make a vow, too, so when you see Nao-chan again, it'll be real special.
