@nrexplain haha, cheers, but using bakarina as your example is a poor choice for deeply flawed protagonist : Everyone in that story loves her in spite of how gross she acts. If your idea of a deep flaw is male repellant, well, the males in that story don't seem to mind haha. Its been a while since I read that, but isn't her ever-growing harem the result of people liking her for what she is? I feel like its the complete 180 from tearmoon as only bakarina ever seems to misunderstand the chaos she has caused. Granted, Observation Log also does this, but the main character is the prince, not the villainess: punctuated by the fact that he thinks villainess' misunderstandings are hilarious.
Tangent, but, I read a lot of villainess sub genre stuff as i'm always on the hunt for stories like tearmoon or the villainess wants to make her husband slim down where the original personality doesn't get murdered. Bakarina I will acknowledge for popularizing the genre, but my god that main character is such a waste: She is completely uncute after original personality is murdered despite that character design looking so top tier for villainess. Typical story for most villainess novels alas.
