【Celebration】 I Transferred to Another World, Became a Holy Maiden, Got Engaged to the Prince, and Was Happy～But Then My Engagement Was Suddenly Broken Off, So I'll Take Revenge on a National Scale～【Curse】

[Cumulative 7000 PV Reached! Thank You So Much!] In a complete turnaround from my mundane life as a plain office worker doing tea duties, I, who suddenly found myself transported to another world, became a saint and used my strongest and most versatile magical power to elevate a weak nation into a great power. Thanks to that, the people of the country revered me as a saint, and I even became engaged to a wonderful prince. An engagement to a prince of destiny—wonderful! The two of us in love were always together, and the people, castle staff, the king, and the queen all blessed us. Then, at the height of such happiness, I was suddenly presented with a broken engagement. The reason? A political marriage, of all things. Moreover, they presented it to me mercilessly, as though they had forgotten everything I had done for this country. The castle staff, whom I thought cared for me, also turned cold gazes upon me. After enduring strict royal education and faithfully serving this country as a saint, I can no longer forgive this! Thrown into the depths of despair, I swear revenge against the prince and this country. Most of this country relies entirely on my magic as a saint... revenge will be easy. *Also being posted on Kakuyomu.
