"I Reincarnated as a Mob Young Lady, but Since the Delusional Heroine Took My Fiancé, I'm Going to Marry a Sparkling Handsome Man Instead"

Charlotte, a mob baroness who was reborn into an otome game she knew in her previous life, is engaged to a mob marquis's son. When she enters the academy that serves as the game's setting, she meets the heroine. For some reason, at the early stages of the game, the heroine misunderstands something and steals away the marquis's son, leading to the dissolution of their engagement. This is a story about Charlotte, who takes no damage whatsoever from this, being stopped by an idiot and the heroine after advancing to her second year.
