You're not wrong. That was a twist I was thinking of adding, but the story would've gotten too long for the idea I wanted to put out there. Other than the coincidence of going to write the same thing in the windmill book, it's just as likely to be some random stranger that had the same idea, but I figured it wouldn't really matter if the lesson he takes away came from his actual previous self or not. If he can't remember a single thing about his past life, and has no knowledge of what his future self will be like, then the reincarnation would be indistinguishable from a stranger anyways.
