悪役令嬢は隣国の王太子に溺愛される

The day before graduating from the academy, Tiararose Lapis Clementille catches her fiancé, Crown Prince Hartknights, embracing another woman, and the shock brings back memories of a past life spent playing the otome game The Ring of Lapis Lazuli. In that game she was no heroine but the wicked villainess standing between the prince and his true love, Akari. Resigned to her fate, Tiararose sits through the graduation party as Hartknights accuses her of tormenting Akari, breaks off their engagement and banishes her, until Aquasteed Marineforest, prince of the neighboring kingdom, steps in and proposes.
