Synopsis
A young Japanese office lady is killed in a vehicular accident. After losing consciousness, she awakens in another world in the body of Iris, the antagonist of an otome game she had been playing before her demise. To her shock, she discovers that she has reincarnated at the exact moment where Iris' former fiancé, Prince Edward, confronts her in front of the entire school over her bullying of Yuri, the illegitimate daughter of a baron and the game's heroine. Thinking fast, Iris manages to leave the school with her dignity intact and upon returning home, is also able to avoid being sent to a nunnery, the fate of the original Iris. Impressed by her rational thinking, Iris's father Duke Louis de Armelia leaves her in control of the Armelia fief in place of her brother Bern, who is one of Edward's supporters and is also in love with Yuri.

As the series progresses, Iris uses her previous life's knowledge to bring about major, positive changes to her fief and the kingdom, such as the concept of banking and schooling for commoners who would otherwise not receive education. She also introduces commercial products that had not previously existed or were only available in a crude form, such as chocolate and cosmetics, going so far as to start her own successful corporation. This brings both positive and negative attention to Iris, her family, and the fief, especially as it angers Prince Edward, who wanted her to be severely punished. It's also shown that Iris was not responsible for all of the bullying claimed by Yuri, as she had only spread rumors and made negative comments, and that Iris was a far kinder person than the one portrayed in the game's storyline. Furthermore, Yuri's personality is shown to possibly be a facade. It is also hinted that she is a foreign spy sent to disrupt the kingdom and that she is purposefully draining the kingdom's finances via Edward under the guise of charity in order to weaken it against an impending invasion.

Iris finds herself and her family stuck in the middle of a succession crisis over the throne, as there is a vocal faction of people who support Edward's older brother Alfred, who is reported to be traveling to gain more support as well as to avoid assassination by his stepmother, the mother of Edward.
