On the night of the wedding, the Crown Princess takes action.

While it sounds good to call it the foundation for strengthening relations between nations, in reality she was merely thought of as a tool. Both countries treated her only as it suited their convenience. Having carefully planned everything, she decided to take grand revenge. Please note that there are some extreme expressions in the middle of this story. [Afterword] The story ranked 2nd in the daily rankings (10/3) and also appeared in the weekly and monthly rankings. Since this is a story where the protagonist is often oppressed, I was uncertain about it, but I'm delighted that more people appreciated it than I expected. I also understand that you read my previous works as well, which was very encouraging. Thank you all very much.
