otome game no hametsu flag shika nai akuyaku reijou ni tensei shite shimatta

I recovered my past memories when my head was hit by a rock.I am Katarina Claes, the eight year old daughter of a duke.Whilst embroiled in a feverish nightmare, in which the prince’s fiancee was determined, I have realized that this world is an otome game from my previous life.Also, I have turned into the villainess who interfered with the romance of the capture targets…If the heroine got a happy end, I would be exiled, but if she got a bad end, I would be killed by the capture target…I have no happy end?! Why is it all bad?!Somehow I have to avoid the destruction end, and reach old age peacefully!!!
