Akuyaku Reijou wa Ringoku no Outaishi ni Dekiai sareru

One day before her scripted downfall, Tiararose Lapis Clamentille recovers memories of her previous life and realizes she is living inside an otome game she once knew by heart. Unfortunately, she is not the heroine but the villainous fiancée of Crown Prince Hartknights, destined to be condemned, publicly rejected, and banished so the heroine Akari can take her place.

Tiararose prepares to face that ending with dignity, only for the game's route to break when Aquasteed, crown prince of the neighboring kingdom, steps forward and asks to marry her. A future she never saw in the game suddenly opens before her, but Akari and the coveted power of Holy Prayer may still have enough influence to threaten the happy ending Tiararose has finally been offered.
