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

At the age of eight, Katarina, a girl of noble birth in another world, has an accident that unlocks her memories–of playing an otome game that’s exactly like the life she’s living now. There’s one problem: she realizes that she’s playing the role of the villainess, and only bad endings await her! What will it take for her to “break the game” and live a happy life?
