Nokori Ichinichi de Hametsu Flag Zenbu Heshiorimasu 1 (Regina Books) [Light Novel]

[Machine Translation] Alexandra is a duchess of the Kingdom of Tarakonensis. It was the day before the absolution event that she realized that she was the villainess of a girl's game! Alexandra has already inflicted a lot of ill will on the game heroine. The game heroine has already had her way with the crown prince, Alexandra's fiancee. The crown prince seems to have fallen in love with that potato woman. It is obvious that he will denounce her and break off the engagement tomorrow. But I don't want to be condemned for being honest! I'd rather show my disdain to the people who disrespected me! Alexandra is now on the move to defuse an absolutely desperate situation with only 24 hours left to go.

タラコネンシス王国の公爵令嬢のアレクサンドラ。彼女が、自分が乙女ゲームの悪役令嬢だと気がついたのは、なんと断罪イベントの前日だった!すでにアレクサンドラは、ゲームヒロインにさんざん悪意をぶつけたあと。というのも、ゲームヒロインが、アレクサンドラの婚約者である王太子に手を出したからだ。王太子も、どうやらあの芋女に惚れてしまった様子。このままでは明日、糾弾&婚約破棄されることは明白だ。だけど、素直に断罪されるなんて、まっぴらごめん!むしろ、自分を蔑ろにした人達へ目に物見せてやる!アレクサンドラは残り二十四時間で絶対絶命の状況を打開しようと動き始めた―。
