Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta...

Eight-year-old Catarina Claes is the only daughter of a duke, living her life peacefully and without incident until she hits her head on a rock... and then remembers that she is not actually the duke's daughter. She used to be an otaku who died on her way to school after spending the entire previous night playing Fortune Lover, her favorite otome game. After noticing that her current surroundings seem oddly familiar, she is shocked to discover that she has been reincarnated into the world of Fortune Lover as the villainess. The villainess in the game usually winds up dead or exiled, so Catarina decides to use her knowledge of the game and its routes to avoid any bad situations. But is it even possible for the villainess to reach a good ending? [Written by MAL Rewrite]
