Haaaa it follows historical asian noble arrogance to a T... in otherwords it does nothing different from others at this given moment.
Also there's like 3 plotholes
1 Who heals the princess the first time cause it seems to have been the blind maid, which wouldn't be possible cause they have the power of prophecy.
2 assuming the Princess gets injured often, why is no one looking into why she gets healed if no one sees her go to her father? Sadly with a lack of info idk if it's often or not so moving on.
3 is no one gonna question the adultry? The prince has red hair, if the prince found out from a book, then why doesn't the suppoaed father? You can maybe make claims of old generations, but somehow I doubt you could here as no one made that excuse so far.
In closing I thought the petals in the cover was blood, and I was gonna be very excited for a killer female MC but I only now realize after finishing the original comment that it ain't blood and now I'm disappointed
