Yes the above was not a spoiler. There's only one possible reason she knew the name Slorenian, s prince from another country, when we now know that Castor was the villain of the novel.
But the following is a spoiler so please read at your own risk:
Ashley will hate the Duke because he was always standing by, never helping her each time she died. I highly doubt romantic feelings will all of a sudden spring up between them even if she does eventually let go of her enmity towards him completely.

the blue haired guy is the male lead and they’re not related so even better
