I'm trying to give this the benefit of the doubt, and when it's good it's really not that bad. But when it's bad, it's pretty bad. It doesn't help I had to go find the early chapters elsewhere. I'm leaving this unmarked for spoilers because it's more commentary on general plot and not specific events, but take caution if you feel these could be spoilers for you:
Where to start? Main character is a bit of a mary sue. Maybe more of a Purity Sue? She just naturally is perfect at everything she does and is able to convince all the good people of her goodness. But for some reason, the good guys can never get an actual win nor prevent the bad guys from constantly attacking and harassing her. Despite the fact she wins nearly every one of this public trials by mob, the bad guys rarely suffer any actual consequences and simply retreat to plan their next attack against her. That's like 98% of this plot, just repeated unfair attacks where winning is just squeaking out a tie, but if the bad guys win just once then she loses everything.
For me the biggest crime though is a lack of certain internal consistency or logic. Two blessed girls are found and both of them are under the control of people who clearly harbor thoughts of social climbing at best and insurrection at worst. Both of these girls should, by all rights, be isolated from these negative influences and put through a thorough education to catch them up. They're supposed to be like 16 years old or something I think, but one of them acts like a spoiled toddler. The other is constantly coming up with good ideas befitting her role as a blessed girl but in both cases they're just sitting around idle so their respective supporters can use them for political games and neither is being properly trained for politics or public ceremony. Even if the main character wasn't even part of the story and the redhead girl WAS the real princess, she should never have been allowed to continue acting like a brat nor interacting with people who clearly are using her in plots against the royal family.
The evil duke and nanny are constantly getting caught (along with their chosen pawn) trying to attack and harass the main character or other plots and yet they are allowed to continue to meet with the king and interfere with both of the girls. One or both SHOULD be investigated for their roles in whatever happened with the queen and probably kept under lock and key until that's over.
Edit: I meant to mention this earlier, but this is also one of the plots that's convoluted and contrived to squeeze out a lot of unnecessary drama for its own sake. It might not have been as interesting but they could cut down virtually all of the dumb events by 1) simply not fighting for MC to be a princess and letting her be a saint or w/e. She would be happy and respected and it would make further attacks by fake princess be completely intolerable. Hell, she could even be adopted anyway. 2) As I suggested earlier, isolate both girls so royal family can properly educate and catch them both up. Fake princess is entirely lacking as a member of the royal family so she shouldn't even have time to plot because she's doing remedial coursework. 3) Nanny should at the very least be kept under house arrest and have to clear her name for her involvement in the disappearance of the queen and the poor raising of the fake princess. Even if she is given a pass because the queen indicated she wanted her child to be raised 'normally' there is just too much she is not being held to account for.
