A great example of this is in the synopsis, "Instead, she starts her new life as the antagonist, right at the moment she's being sent to live in a nunnery—for the rest of her life!" Everything that sentence sets up is a lie. All the drama that comes from being reincarnated as a "bad" person doesn't exist, the "antagonist" had a hobby of saving orphans when she was younger, so much for being a bad person. And any threat of the nunnery punishment is dropped like a hot potato, and later after learning more about the characters, doesn't make any sense from a story perspective.
I won't go into any details about why I think she is "overpowered", but in general she applies modern ideas to the fantasy world and it always works out perfectly without any real struggle or unintended consequence.
Art is super nice though and bumps up the overall score for me from a 6 to a 7. The story is fun at times, but, if you are looking for something other than a perfect MC who can do no wrong in a black and white world keep looking.
