The Bizarre Adventure of Miss Capricious

I was reborn into a novel "The Mistake of Cleavens" and became a silly, love-deprived young lady. Fame? Power? Love? Those are not enough to attract me, as I happened to be the richest girl in the world! Yes, I'm going to lead a brand new life with all the wealth I got.
But wait! I seem to recall that the ending of this novel is a bad end?! The world collapsed because Lady Cleavens abandoned a cat, which brought the doom of the world!
Alright, even if I need to adopt all the cats in this world, I'll do it as long as I can reverse my fate and save it from its doom!
