I'm the Emperor's Long-Lost Daughter

Rositte is a "reincarnated one," someone who recalls their past life from another world, but is framed for the murder of Duke Luchiaden. She goes back in time right before his death to save him and is shocked when he says she might be the emperor's lost daughter, foretold to be the last reincarnated one! However, Carina, another reincarnated one, insists she's the true daughter. Will Rositte be able to uncover the truth about her origins, or will Carina be crowned as imperial princess instead?
