I really liked this one, at first I'm not gonna lie I got a bit confused but then I thought this story is great, the fact iris don't know the what's gonna happen next since she reincarnated at the last part she knew of the game is interesting. Also I read some comments saying this was bad and she was overpowered, I don't think that's the case, just because her job before was doing others taxes don't say that's all she knew it's like saying I'm a waitress and... more>> that's all I know, we all got hobbies and iris discovering ways to make chocolate I learned chocolate comes from cacao in 4th grade, is she over powered by knowing what I knew in 4th grade? Um no. It's good that she is smart and some said she had no enemies they all loved her, not really, her enemies were big and did lots of harm but by her using her head made it pass through it. She also falls for someone she can't have because of their positions, and some big enemy appeared that says he loves her but he seems like a sadistic Prince to me who wants all her love ones dead and wants to be all she has, idk how she gonna get through This Prince from acacia since I'm only on chapter 233 but its getting better and more difficult for iris. This is a historical, economical, romance and political story if you don't like that, then don't read, dont ever give a bad review to something you read only a couple chapters to, and most important I believe the translators do a great job, my favorite one is Djurassico idk if I spelled it right but he or she is really good. <<less

Such an interesting story. I love seeing her grow so much in a short amount of time. Now, just waiting on her love story with Dean to really start and on everyone to find out about the chosen princess' REAL personality.

It has an interesting story, the girl reincarnated and merged within a noble girl called Iris who is an otome villainess, she is humiliated in front of others for the bad things that she did and she "struggles" because she is a duke's daughter so she brought shame to her family and she loses her standing in the noble society. She uses her memory from her previous life, creates a company etc etc... So far it's good.

The problem is that there are a lot of things that are hard to... more>> understand and there are some inconsistencies. The first thing is how can people still support her and sympathize with her? well, I understood it after 40+ chapters after someone in the novel explained so all is good but still, I was a bit lost at the beginning.

The second thing is that at some point in time, I was like "what the heck was her job in her previous life?" although she presented her job at the beginning, sometimes, you can be dubious if she didn't have 4 or 5 jobs at the same time... while I can understand that some people DO make their own conditionner/shampooing, and some people DO make their own chocolates (so it makes some sense that she can introduce all these and start a business with these things), but how can she know how to deal with territory management or how a bank works? How can she know about laws, reforms and all, and convince people in such a short time to change their laws? And because she knows aaaaall these, she accomplishes things too easily. Well this is a problem that is in most of the isekai novel involving politics/economy so it's not like it's new but still... And most importantly, how come she has the time to deal with all of them at the same time?? I mean she is doing too many things, it's hard to understand how she manages her time...

The last and the most important problem is that the people against her always have bad personnalities or are just foolish, and the fact that Iris was really kind even before they "merged"... it's kind of like the roles are reversed... Iris is supposed to be the villainess but she has an unexpectedly good heart. Her ex-fiance is unexpectedly foolish, and has such a big pride and such a bad personnality, even though he is supposed to be an ideal prince in the game.

Yuri who was the female protagonnist in the game being such a manipulator and such a b*tch


Nonetheless, even with these problems, it's a good novel: the plots are interesting, the pace is good and the fact that they skip some days sometimes don't let you feel bored.

And it feels really good when you see the guys regretting how they humiliated Iris :D

A bit different from your common isekai novels. I'll try to refrain from spoilers.

The story is pretty good, the MC slowly develops her fief using her previous life's knowledge as a tax accountant. She pushes reforms aggressively and the fief develops smoothly. There are frequent time skips as well; reducing detail but progresses the story well, over matters deemed trivial.

The story does lack a concrete villain even up to the chapter I am currently at. The villain of the MC is depicted as a certain group, a country's actions, and... more>> other nobles so it is hard to say who is the main antagonist. They use the lack of clarity regarding this to effectively etch out parts of the story.

The side characters do not have much depth in early volumes, they are usually loyal to the MC and early on they usually are in shock and awe of MC. Later on, you'll see more excerpts and chapters about side characters POV and their development.

Essentially the biggest flaw in the novel for me is the translation. Japtem released clear translations while the next few translation teams did their best there were definitely names of characters, tenses, and clarity lost or mixed up. Also at the time of reading this, shirotranslations is down so it was difficult to hunt down those chapters unless you go to an aggregate site or access it through google cache.

Personally, I hope new readers and old alike read this novel to its current chapter. It is definitely a good read if you don't standardize your ideas on how novels are written. <<less

Incredibly interesting, barely any filler like in a lot of novels and the tedious nature of most political/business novels (taking 50 chaps to start the business or 30 just to get on their feet) is completely eliminated with skillful (imo) use of time skips. The synopsis is a little misleading however as the premise that this is in an "Otome game world" is only relevant for the first 3-5 chaps (I have read up to 84 so not sure if it will resurface later) however this is an incredible read... more>> if you like an MC who is truly smart and adept rather than the author simply stating that they are. The political and financial moves the MC makes are well thought out and logical, truly a work deserving of 5 stars. <<less

I like the story, its kinda fast pacing story. It was translated by JAPTEM.

I dunno what happen, but there's no more updated translation in this team.

I found this novel yesterday and I finished reading it today morning. So you can say Im a BINGE reader.

... more>> The plot is okay, very readable how it was translated. Im just wondering how the MC, switched in the story. Because there's no story about that details.

The length of the story per chapter was short for me. So the more details, let say it was remove. But still you can imagine how the story goes.

And also, since it was a fast pacing story I just find it Lacking in Surprise Area, yes the MC she's making her fief revolutionarizing but thats I want to say its so fast.. Hehehe.

But still I like it.

I just hope there's a more in deep tackle of the characters in this story.

Because I finished reading what the JAPTEM TEAM translated yo v1-v2-c51. As for now, its my opinion..

Now let me see the other translators did on this Story. <<less

Iris is a hardworking woman. Even so, she is soft hearted and very kind. She's the epitome of a saint that works hard towards an ideal goal. She has many supporters who stands up for her at all times. She is a queen fit to lead.

This novel is very different from those other transmigration novels. First of all, she was right at her bad end when she transmigrated. She also has her memories and it's more like her personalities mashed together than one taking over the other. She has a... more>> great deal of resolve and knowledge. Although, regrettably, that knowledge is somewhat excessive deus ex machina for supposedly normal salary woman who works with taxes.

In the beginning, there's some info dumps on character introductions and setting so it's a little confusing. Even so, it's enjoyable seeing her manage her fief. The real thing basically starts when she made her re-debut in noble society after her bad ending. It basically is the internal strife between the princes. One of things I want the novel to tone down is the switch in perspectives. Although it is helpful and interesting, doing it too much is also very messy and hard to understand. The romance is cute but is not very developed as it is somewhat one sided on the ML side currently. Although I would love for them to get together but the ML is hesitant to chase after Iris so I don't get much hopes of improvements right now.

Currently, in the story, there's not much complex plot lines happening so there is much to be anticipated. I hopes it continues to dive deeper into the main conflict and drama. The characters are somewhat bland and not much character developments but then again, we haven't gotten to know much about the characters yet. Just the outside descriptions currently appear. Even so, they are pretty likable. Overall, it's certainly interesting but just waiting for it to get more in depth and angsty. 4/5. <<less

Shoujo is the tag, but do not get it wrong that shoujo are full of romance inside of it. Nope, this one had not, or at least yet. It was all pure business, how to get back up from being shunned by the society, but no hardships whatsoever her, she was away from those who could mock her afterall. The business part was nice, but as expected of shoujo, there was not any detail of "building up to success", the MC just implemented her idea then "skip!" it was a... more>> great success without any problem, this story is for teen girl, so no to heavy stuffs. There were also changes of PoV which was nice too. So far no hardships, or maybe conflict, the main problem was still a mystery, such as "the original main heroine" what was up with her butt!? <<less

My absolute favorite reincarnation into an otome genre novel. Heroine has past knowledge which makes her decision making processes (and her overworking) seem believable, but there's still enough mystery to make it intriguing.

I first found this story while reading the manga adapted form of it. Thinking nothing of it besides how beautiful the art is, I got drawn in by the plot and how she handled things that were thrown at her. Now that it got me hooked, I went ahead and found the novel and read the entire story up to where I had to wait for the next chapter. She's a female lead that I love (strong, capable, witty, beautiful, gives no fudge about the people who threw her away)... more>> and wish more authors would create *COUGH SHOUJO AUTHORS COUGH* and you can say this novel is what got me hooked into reading more light novels than manga nowadays. I hope she gets her happy ending. TL;DR: Came for the art, stayed for the plot. <<less

I really like this. Although it follows a common trend of reincarnated-into-an-otome-game-as-the-rival, It's unique in how they have it set after the "game" is over, or the bad-end flag is up. The character is also relatable and likable, but not too OP or pulling a reverse harem situation. Although some elements are a bit generic, it's still a solid, well rounded novel that many will enjoy. The pacing is a bit fast in the beginning. Compared to the manga, it skips some parts, but it's still good.

Love this series!!!

A mix of otome game and political dabbling but there is also the deeper element where the prospect of an evil heroine or just a strangely 'empty' one now that the game is over is SUPER EXCITING. Ahhh Oujo-sama, please go on exciting exploits and clash against the prince and his airheaded (or genius-actress) fiancé. Oh and a romance better be raised soon.

"Common Sense of a Duke's Daughter" isn't just your average Otome game novel with a noble villainess. The MC isn't a super super sweet, dense, and dumb like all the other MCs from other novels involving Otome games. I also love the fact that the MC didn't start out from the beginning of the game, instead of the she started at the end, which brings the reader to wonder what she's going to do next to escape her destruction end. Also, I like how the MC doesn't make a harem... more>> with the captured characters. I enjoy the slow romance between Iris and (you'll know who if you read the novel, so READ THE NOVEL). I learned a lot from the way of the MC's thinking and her knowledge of politics and her actions to help her fief. I love this and find this novel as a jewel among the other similar novels. <<less

First I read the manga, because I like the plot and bored for long waiting update I was searching the novel and I really like it.

Its different for other otome reincarnation novel whose MC try to twisted the bad ending. The story is about how to survive after the down clif of life and how to revenge in elegant way to her ex fiance and his lover.

I hope the translator continue to translate this novel because this novel is really good.

First I started the manga and because the plot looked funny I started the novel. I find that the novel is a good relaxed and interesting story, but it's true that the developments is too slow and the Protagonist is too perfect.

One of otome game story I had been reading so far and so good. Protagonist's character similar to "Kenkyo, Kenjitsu o Motto ni Ikite Orimasu" but her action been more like "Botsuraku Youtei Nanode, Kajishokunin wo Mezasu". Very intresting story.

Initial impressions as of ch.3. Rated 3.5, rounded up to 4.

An interesting hook. Somewhat like "Kenkyo, Kenjitsu o Motto ni Ikite Orimasu", the MC found herself transmigrated into the villainess of an otome game. The difference is that when she arrived, she was already careening towards the bad end. Bewildered by her sudden condition but remaining calm, the MC goes through the motions just like in the game, adding her own flairs and to change her image from a bully to a defeated but still proud noble. The first three... more>> chapters thus far feel just like a teaser but already the hook seems interesting as the MC will try to struggle against the terrible ending in store for her. Will be reading this, and update accordingly once more chapters are out. <<less
