I Possessed a Villainess, but I Wanna Raise Cats!

I transmigrated as Rowaine, the villainess who was executed for abusing a werebeast. In order to escape death, I decided to replace my sister Linier in her arranged marriage. The problem is that Duke Blois, the groom, is a cat werebeast who is known as a bloodthirsty battlefield monster… “My dear, I heard your hobbies include abusing werebeasts like myself.” “I haven’t heard of such a condition stating that women who abused werebeasts could not be Your Grace’s wife, though.” His emerald eyes flashed dangerously at me, I quickly kept speaking before he could say anything. “If my hobby is a problem, then I promise that I will never abuse you, Your Grace.” “Ha– what?” This is the story of a ten-year contractual marriage between a cat lover and a prickly cat werebeast.
