Headscratchers / Bokura no Kiseki

• Why do Hiroki, Nishizono, and Nanaura believe that Harusumi can't remember anything? They saw a notebook full of memories from the past that belonged to him.
  • Maybe they weren't paying attention to it (and considering it was written in Japanese, they would have to pay attention to actually read anything of value), or they thought he was simply writing down what those around him said in order to find out who he was (in which case it wouldn't matter what is written there, would it?).
  • It's also possible - if not rather probable - that Harusumi was writing loose details about life and magic in Zerestria to try to put his thoughts in order, rather than writing specifically about himself as Veronica. He started writing things down to help recall how to work magic, after all. With Zeze already claiming Identity Amnesia but still recalling the world they lived in, Harusumi could also safely make the same claims. No, the real headscratcher is why nobody now seems to remember back when Harusumi claimed to be a reincarnated princess several years ago and now put two and two together, especially since the story of that claim has followed him around since then...
    • The reason for that is most people in Harusumi's class weren't from his elementary or middle school. He claimed that he was a princess in elementary school. Some people in his middle school were from his elementary school, so that reputation carried over to the first year of his middle school, but others weren't. Also, he's been trying to downplay that claim since he met Kamioka. So by high school, most people don't know about it. Now Hiroki did overhear that Minami was a princess...
