Unlike some, I'm enjoying these 'filler' chapters. If the story had gone straight into revenge and fight with the imposter, it would've been too much to process. Now she's loosening up, learning to live and make friends. When the imposter comes, she won't get flustered because she now has friends and allies, and she no longer cares about earning her father's love.
I think the imposter will have a harder time convincing the father now that he has prophetic dreams. I can't wait to see the father confused about why his daughter doesn't give two shits about him and the imposter.
