I'm in Love with the Villainess

Oohashi Rei, an ordinary office worker, is overworked to death and suddenly finds herself reincarnated as Rae Taylor, the heroine of her favorite otome game, Revolution. However, Rae has no interest in the game's three original romance routes with the Bauer Kingdom's princes. Instead, she sets her heart on Claire François, the game's main antagonist. Using her knowledge of the game's events that are yet to come, Rae tries to give Claire a happy ending before the coming revolution destroys any chance of it happening.
