It started out very nice and well-written. The reincarnated story was believable, the MC thinking and emotions are realistic. I like the MC personality, strong and determined, and there is little romance (no MC fall in love too quickly with some random nice handsome rich amazing genius prince).

The reason for the low rating is because I just got bored of it. I just find it repeating itself and cannot be bothered to pick it up again. Maybe someday I will re-read and change my review.

It started out REALLY great, I was hooked! But lately... it just drags on and on. It has some forced, out of character moments that are unnecessary and painful to read. It is probably because the author has run out of material but wants more length. It interrupts the flow of the story. It's common amongst these type of novels, to have entire chapters showing the main character's thought process when the same decision could've taken a few sentences. It is really only there to justify how righteous the main... more>> character is. Will drop. <<less

I started reading this novel because I saw the manga or comic version first. The comic is really good but the story isn't complete yet and I found the light novel. When I read the light novel I got really hooked. I recommend that before reading this LN started first with the comic you can just search for it in manga online with english translation. Hope you find it.

Btw I like how cool, kind, and strong hearted the MC is. I hope you love the MC like I do.

I am hooked to this novel because of the illustration. It is very beautiful ♡. The story also not bad. The plot is not deep. So if you just want a light reading, this is for you. I have hope in the future chapter the author will give a deep and complex plot. I am more looking forward for the romance though. ♡ I love Dean.

The story itself is a typical "reincarnated into villainess noble girl" story. The smart female lead is a point plus to me, because I am... more>> sick reading a dense female lead. Although at beginning MC is supposed to be villainess noble girl, there is no evil bone in the MC. Even the original MC is so kind that she took homeless orphan to her house. It confuse me. How can a kind hearted girl like this has a villain label? <<less

This light novel is interesting. A business woman is reincarnated into a otome game being as "wicked" daughter of a Duke. After her broken engagement with the Second Prince, she starts her journey with her fellows in order to seek the happiness. With her modern knowledge (economic and politic), she stays in her hometown and she trying to built a beautiful place for everyone. And like all story of the time of kings, there are the fight for the throne (fraction, corruption, manipulation...)

It's not a classic reincarnation story with... more>> magic, combat (no many physical) or anything else. So that's why, it's pretty good, interesting and novelty. Moreover, we start the story with a strong and beautiful protagonist so it's perfect for me. <<less

I don't have anything negative to say about the story or characters themselves and i'd say that this is a must read, the only reason I didn't give it a 5/5 is because the pacing was a bit off imo, things just happened too fast at times, a problem would occur, and within a couple of chapters would be fixed, now I don't mean it in the sense that the story skips things or that they happen "off camera", but for instance an entire battle would start and end within... more>> a few sentences, the fight would start, someone would charge, cut a couple of people, and done, whole battle over, and that happens quite a few times, if only some plot points were expanded upon a bit it would be perfect. <<less

First off..

  • MC is thought of "mary sue", but personally, I think her past life was just such a workaholic tax accountant that when she started with improving the fief, her knowledge kept on growing that with addition to the new departments she kept on establishing, she felt it possible to put on policies that were "common sense" to make the people's lives more on what was like in the modern times.
  • Male Lead is a "gary stu" but in a way, I could just accept that he is born a prodigy and that by travelling and studying under merchants and having "real life experiences" is what just established the meaningful reason behind being a genius as close as, or even above as the MC with her past life experience and knowledge.
  • I liked how the narrator made the challenges well above the MC's and Male lead's current IQ's making it give them actual hardships and not just focus on the romance.
  • It's almost unfair that the MC already had capable servants at her disposal but it actually tied together the personality of the MC with the workaholic of her past life.

    What I mean by this is that, with her unusual personality of asking for street orphaned children as "presents" for her rather than gems and diamonds and that after her denouncing and being appointed the fief's proxy, there was nothing too different with how she acted in either pre and post past life memories. Her family saw nothing of her changed much other than that she just grew out of being a child and matured into a fine noble -- meaning no one questioned her actions once she did all sorts of reforms with her fief.

  • I love the romance! The progress was neither too slow nor too fast and not unreasonable. They were attracted by the other's work ethics and slowly grew into a romance where they want the other to be by his/her side. They have their sweet moments and tragic moments. The introduction of a potential rival is also not unreasonable and very much in tune with the progress of the story!
Now I'm just waiting for the next chapters but I do hope that the potential love rival can match up to the leading male char.

This is a good read, very recommended! The only trouble is the amount of translator groups this one has. If u can organize how u read it, u can make sense of the story. That just means this is so much of a good story that a lot of translators are willing to translate it! Hehe

That's the end of my review. I hope to see new chapters soon and very much appreciate the work that is being done for this story. Really, I feel so thankful! Definitely one of my faves. :)

It's a pretty good story. I like the characterization but I think there's a lot of unnecessary details. The author has been too focused on describing how brilliant the MC is. There's plenty of skipping scenes, and I need more chemistry between the MC and the ML. By the way, when I read this, up to chapter 85, the website of asian hobbyist cannot be loaded, I wonder why. I hope it will get fixed soon so I can continue reading. Good job, anyway.

The premise of this novel is quite good and has a lot of potential, however there are a lot of problems:

-The MC is just way too perfect and super intelligent, in other WN the protagonists are just s*upid and dense, but here we have the total opposit, with her knowledge from the real world she can solve every problem without any sort of struggle.

-The author skips a lot of details, for example: the MC has to visit her land to know what's going on, in the next chapter she tells... more>> us that she did it, but we don't know how, when and what happened while she was visiting.

-Another thing that I dislike about this novel is the army of capable servants that the MC has at her disposal. These servants are the poor children that she picked up in her childhood, they have no personalities and are just tools that the MC uses when in need. <<less

I absolutely LOVE this novel. I love how the MC becomes reliant on herself and doesn't even care about her past grievances. I love her mom, her dad, and her attendants. And I love how people are starting to realize who she truly is. I also love her budding romance, and how that relationship is making them both realize and overcome their weaknesses. Overall, I just love this novel.

This is one of my favorite novels here, translated by one of the best translation groups. I love the fact that the MC is a strong woman, who doesn't simply cry or try her best to win the 'engaged partner', like most of the reincarnated villainess stories. After being expelled from the school and publicly humiliated, she decided to built her reputation little by little, with the help of her trusted personnel. Granted that her knowledge about certain things may be exaggerated a little, other than that, I like the... more>> things that she does to built the land entrusted to her by her dad. The romantic relationship also flows nicely without any cliche story of "love at first sight" or typical shoujo doki-doki moment.

Translation wise: So far the translators did a good job at translating this novel. Thank you to all translators for doing a good job here. <<less

I found Duke Daughter through a manga but the manga version is so slow and I can't bear wait any longer 😣😣😣

So I drown my self in the internet looking for development of Iris life and here I am reading through 74 chapters within a day until my eyes hurt. I've warning myself to stay away from the screen but the story keep provoking me.

I love how the story developed. It's not slow nor fast. The MC is very clever, beautiful, independent, and so kind she's almost perfect.

I hope japtem... more>> continue this light novel soon. I'm carve for DD spoiler and couldn't resist to read the raw which never happen before. I only got slightly hint from the raw, because google Translate did it job awfully. So all I have to do is patiently waiting for the next chapters translated. <<less

Good gods, I think I've read ads in the phone book with more words than the small amount of words per chapter this story has to offer. I couldn't get pass chapter 5, which really felt like it should've been part of the first part of chapter 1 - in terms of pacing and length. Everytime the story started to pick up speed, the chapter comes to an abrupt end. Can't find myself willing to recommend this to anyone to read - as there other similar stories out there like... more>> this that're written better with far better pacing. <<less

My reviews tends to hint at parts in the story, as most reviews do, but I'd still recommend for you to skim or skip this if you want to go into this blind. This may change depending on future chapters.

First of all, I finally got around to reading this... I saw this as a high rated novel after going through my evil-villainess reading spree, and the short story here is: I'm disappointed. Like some other reviews have stated, this whole story feels like a wasted potential- but since the... more>> potential still exists, I'll try to read it till the end.

Like most broken-engagement stories, the "capturable characters" are the "bad guys" and the protagonists are the "good guys." Unfortunately, like most broken-engagement stories, the transition from being a "bad" to being a "good" person is nonexistant- because the "evil" villainess was the good person this whole entire time, even before the reincarnator merged with the protagonist (a counter example to this would be Haunted Duke's Daughter.) This isn't the only novel that has this fault, so I'm not too angry, but...

The protagonist. I know many light/web novels are overran with overpowered protagonists, and I honestly don't mind that if its realistically done and well-written. Unfortunately, here, she's a beautiful young woman with faults that might as well as be her strength. Basically, she's surrounded by people who love her for her faults (ex- her princess-like naivete and kindness). If these faults were expanded on and actually hindered her instead then I wouldn't have been as annoyed. Another reoccurring problem is how her "real world" knowledge seems too broad for any "normal" person from the "real world" and is often used as a plot convenience, but then again, this is a common problem in many LN/WNs.

While the event climaxes and plot twists are predictable and boring, I do love the premise of the main story and the economical and political aspects of her fief. Stories about business and politics nearly always at least get a two star from me, and the writing is decent. It has an addicting quality to it, and I do look forward to seeing how she maneuvers her way to success.

Of course, these aren't all its faults/redeeming qualities, but these are the main things I took note of. All in all, I'd recommend it to any fan of this genre, though I do warn that you shouldn't expect deep and complex characters or a realistic world. <<less

A great read, the otome game reference is only at the beginning of the story since it's a story that's started at the epilogue of the game. The MC is smart and hardworking, not that dense in romantic sense either. While she's moving a lot, there's a lot of things happening behind the scenes from side characters, some of them are aiding her and some of them are hindering her. Though some people write that she seemingly never got adversaries it's a wrong accusation, she does got adversaries, most of... more>> the time the enemies are plotting to strike down her and some of them are actually heavy blow to her image. She needs to work hard to recover from the schemes that's thrown at her. <<less

While the focus on the business and politic is quite interesting, the pacing is simply too damn fast and MC just keep raking in achievements with minimal problem. Details have been skipped. It feels like everything has been hand waved.

For example, she started a business from nothing to success in two short chapters. And establishing banks in another few chapters. The challenges of making business and financial institution are ignored.

The worst part of the novel though, is the execution of its premise and its characters. No, the MC is not... more>> hated, or even that disgraced. She is loved by many influential people and her own vassals. Her land is rich and she has control over it. She does not need to recover from any hardship that was promised. She just need to build an already reasonably developed land.

And the real 'villains' the 'heroine' and the capture targets are just pathetic spoiled kids.

Decent, cannot say it is great, bit at least decent. <<less

The MC reincarnates as the villainous character in an otome game after failing to take down the in-game heroine. She’s disgraced, heartbroken and expected to return home to face confinement. However with her new awareness, the MC is able to analyze the situation, realizing the inate good within the original character, and utilizing her strengths, resources and social relations to create an alternate path for herself. Extracting herself from the complicated and flawed love polygon of the game to focus on political, socioeconomic issues of the period through various alliances, political and economic reforms and business opportunities.


The original character was usually kind and caring, but due to losing her fiance, acts in a petty way towards the in-game heroine by spreading rumours. While the current MC is indifferent to love but smart and strong-willed, while maintaining the original care the character had for citizens and the poor. While this can be seen from their actions, neither have a truly distinct personality or any characteristics that make the MC stand out from other time travelling or smart leads and the character is quite standard.
Some side characters are introduced, and the servants the MC will use to implement the reforms are likely to be recurring. Aside from the male characters being handsome, there’s nothing distinct about them as they all fawn over the MC’s gentleness, their past debt from being rescued by her and how intellegent the current MC is.


The story starts with a similar concept to Chu Wang Fei and various other Chinese light novels, with a soul arriving in the body of a scorned woman and utilizing the character’s strengths and their own knowledge to carve a better future. However it quickly rises above the petty squabbles and revenge schemes that usually follow. Instead the MC takes an idealistic route of bettering society rather than focusing on romances, becoming a powerful figure within the new world. The plot and tone is similar to Maoyuu Maou Yuusha, as both aim to give two-dimensional and villainous NPCs depth and sympathy through exploring their backgrounds. The feeling it gives also resembles Wolf and Spice i.e. The explanations, economic focus and setting.
The story is not the most original and the plot is somewhat predictable, but the concept is still interesting and has potential. However since only 20 chapters are translated, we have to wait to see how the plot will grow, and how they handle the challenges they face.

However the story already contains a few minor issues:

1. The sheer amount of benefits and resources the MC has (but conveniently failed to notice due to being blinded by love) makes it too easy to make a turn-around. Simply by making use of what’s in front of her, she could’ve improved her future is several ways. The original losing due to a petty scheme and failing to notice these things (but managing to set it up for the MC) seems almost ridiculous.

2. The use of modern knowledge on businesses and government structures is expected, however when the story becomes too specific with its schemes (and the shock of various side characters) and too ambitious in the breadth of industries changed, it becomes arrogant and overbearing. Just because it’s a shocking idea for the period the game is set in doesn’t mean readers in modern times will be impressed (i.e. OMG this thing called chocolate is just too good, how creative and original – not so much for us) while completely disregarding the knowledge and skills available at the time i.e. Money lenders existed and acted as banks so it’s not like it’s a completely new concept.

3. Use of multiple POVs. The story is about the growth and experiences of the MC after her fall from society. Most of the actions and changes are brought on by her while the supporting cast merely carries it out. Using their voices is just repeating or explaining what the MC has already done, making the story over the top with all the praises, and repetitive (she’s kind and smart, we get it). TBH you can just skip the change in POV – the only one worth reading was where her father mentions that he does care about the MC’s feelings.
4. Characters – as mentioned above, they’re all very generic and flat in terms of personality, tone and methods. Even if the author inserted weird quirks, it wouldn’t make them feel realistic or relatable. The MC is near 'perfect' and her personality has no room to grow, and even the people the original body wronged were evil or sinister, so the MC can do no wrong regardless.

the story is bascically about the MC getting condemed because of being headstrong in displaying her displeasure to the FL (fake). With her status as dukes'daughter she fell from grace, with her arrival it is in turn become milder than the original. (This point is ok since it started with the plot of the game/novel, do not know why others kept seriously critisizing)

... more>>

she goes to her father 's dukedom and manages it, creating innovative products with the products existing in both worlds (i do mot understand why people compaling here, maybe she was interested in how chocolate was made, that is why she knows, and conditioner could be made naturally as well, she is female after all does she not like to beautify herself with natural goods? We do not know as her past was not delve into, but see my point?) banking is easy as well, its the idea of it and execution that was hard, watch youtube videos on how banks came to be or watch how paper money came to be)
them hating her is acceptable due to the premise of what she may or maynot have done in the academy

lastly the case about not knowing the other characters is fully acceptable since we are viewing the world in her eyes. Its up to the author when to shed light. It could be done in an epilouge at the end why so picky? It does not affect the story, infact it creates a mystery.

im at the part where she is accused of being a herectic.


hope this review/rant brings justice to this good novel. <<less
