I didn't understand why she had to leave...

In her dream, he didn't go back to his family, probably becuase he was afraid to hurt her, so she left, so that he wouldn't do that... The thing is her dream was probably incomplete, like I imagine he didn't go back for a specific reason? But that doesn't mean they didn't communicate or see each other the whole time? I don't know, I don't get how she hasn't found out she actually is a Parotbill (or whatever it was called xD)

It's not like that, she's a special kind of beast, she gets promonitions in dreams (dreams about the future), it's just that the first time it looked as if she was reading it in a novel in the dream, so she thought she wasn't her, but actually she probably just dreamt about her past life and the future im this life and confused the two, because the dreams are very realistic, she can't tell them appart from reality, like the second time, she was very confused and very shocked and she just went and did a stupid decision to just run away
The quality of the story dropped, and I'm a fan, it got silly, she transformed into a scarred cat and blushing mess everytime. And, out of nowhere, the plot got super rushed too
