I recovered my past memories when I was hit on the head by a rock. I am Katarina Claes, the eight year old daughter of a duke. In a feverish nightmare, in which the prince's fiancee was determined, I have realized that this is the otome game from the previous life.
I have turned into a villain that interferes with the romance of capture targets... If the heroine got a happy end, I would be exiled, but if she got a bad end, I would be killed. Have I no happy end!? Why is it only bad!? Somehow I have to avoid destruction and reach old age peacefully!! (Source: Novel Updates)
