Novels by author Yamaguchi Satoru

My memories of my past life returned when I hit my head on a rock. I am Katarina Claes, the eight-year-old daughter of a Duke. While I was struggling with a high fever, it was decided that I would become a prince's fiance. I have now realized that this is the world of an otome game I played in my previous life. I also realized that I had become the villainous noble girl who got in the way of the protagonist and her capture target if the protagonist got a good ending, I would be exiled from the country with only the clothes on my back, while in the bad ending, I would be killed by the capture target where's my good ending!? Do I only get bad endings!? I want to overcome all the destruction flags somehow and reach old age!
