Dumped After My Engagement: Becoming a Military Noblewoman Novel

A year after her mother's death, Celestia's father remarries, bringing home a new wife and stepdaughter. Initially hopeful about their relationship, Celestia is shocked when her stepsister claims to be the world's heroine and reveals that Celestia is destined for ruin: her engagement will be broken, her father will abandon her, she will offend the royal family, and her reputation will be destroyed. Amused yet concerned that these predictions might come true, Celestia decides to escape this fate by abandoning her noble life. She turns to her grandfather, a military man, for help, but ends up enrolling in military school and becoming a soldier. Her rise through the ranks is meteoric—she reaches the rank of Colonel and earns fearsome nicknames like "The Brutal King of the Frontier Fortress" and "Battle Maniac." Her military circle soon fills with nobility and royalty, including foreign dignitaries eager to join her ranks. Ironically, while attempting to leave her noble life behind, Celestia's social standing has become more elevated than ever before.
