By A Slight Mistake


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

Sagara Mizuki, who realized she had recollections of her previous life while wandering on the border of life and death, woke up on a hospital bed. And she was surprised that the environment surrounding her resembled the setting of 『Seventh Heaven』 which she unwillingly played before. Her role is the perfect young lady who happened to be the rival of the disappointing heroine 『Toujou Rin』.

However, if observed carefully, there were a lot of slight differences from the game. The perfect young lady named Mizuki became the perfect Prince called Beautiful Crossdresser and her one-year older brother turned five years older.

Without walking along the route of attacking the disappointing heroine, Mizuki began to choose a proper life.

“Eh? Huh? Why did it come to this?”

What will be the future of the girl who started to roll opposite the direction she wanted due to a slight mistake?

Ara, this novel is promising. First two chapters and it already caught my attention. I also love otome based novels so I think that adds to the point. Though I shall withheld any further review since it is just starting. I shall get back to this when there's more translations to this. Overall, I like this novel and hope to continue liking this. Hihi

This is a very interesting novel that kind of ressembles kenkyo but is also different as it takes a more serious tone to the story. The main character is cool, rational, smart, capable and beautiful and she has a trauma that makes her more interesting than other characters. I also really like the relationships between the characters and their interactions towards each other. All the side characters are likeable and have a reason for doing what they do, overall a very nice read. I am really looking forward to reading... more>> more and seeing the characters develop more.

Also, the summary doesn't do justice to this novel, so if the summary turns you off I highly recommend you at least read the first two chapters and see if you like it or not. <<less

The plot is well defined and currently have no plot holes, MC is cool and likable, there are no flaws in his character development with the heroine's love interest. I'm really excited how the heroine will show up and mess the MCs life however before reading this novel I must remind you guys that this story hasn't been updated since new year.

Still hoping for this to be updated

At first I thought this will become somekind of love comedy or friendship building (like reika) but Mizuhime exceeds my expectations. She's smart, rational, and always think everything thoroughly. A beautiful story about human interactions. :D

Story seems very interesting so far. The only gender bender here is that she's wearing male uniform due to circumstances. She's not hiding her gender or anything, everyone knows who she is and why she needs to do it.

I'm loving the cool capable and intelligent MC, especially in an otome kind of setting. She's someone that means business and won't stand for others sh*t. She does things rationally at her own pace and ignores nuisances.

The novel is fun to read and the female lead is quite like likable. Mizuki is smart, strong and independent. The capture targets are also pleasant, well maybe except for one, Suwa. I don't really like him because of the incident with the female lead. Looking forward to the story development and character growth. Definitely recommended to read for slice of life modern otome game reincarnation genre.

As other reviewers mention, the MC is a very amazing character. The way this story is turning out to be is interesting and different form the norm, as a lot of these otome like novels are always so similar in their "fluffy" feelings. However this one feels a lot more believable in characters and has realistic situations that would occur from said characters. I hope that the story continues to generate an original take on the genre and proves to be unique from the other otome based novels out there.
