Hanashi Media also released the light novel series in English digitally.
Here’s a description of the story, via Hanashi Media:
Exceptionally gifted to his own detriment, Prince Cecil had always found life effortlessly mundane. One ordinary day, his life took an unexpected turn when he became engaged to Miss Bertia, the Chancellor’s daughter. This engagement, however, was anything but typical.
“Prince Cecil! I must confess – I am the villain of this story!” Bertia’s declaration was startling. She claimed to have memories of her former life, where she had been the antagonist in a “Otome game”. Her lofty ambition was to excel as a villainess and thus have her engagement annulled. However, despite her plans for various misdeeds, her attempts have always been unsuccessful.
