Whoa, hold on a minute here!
The Queen did not hide Tiara as some form of backup plan. She hid Tiara to protect her from being abducted or killed. It is clearly stated in both the manga and novel. A sickly child is an easy target for anti-royalists, which we already know exist.
She did not hide Tiara's existence from Pryde as some kind of conspiracy, it was hidden from Pryde because you logically cannot expect a toddler or young child to keep secrets. And this particular secret could get someone killed.
And can you stop calling Tiara a backup, because she was never a backup. Calling her a backup would imply that she actually expected Pryde to be eligible as Queen, which was not the case. NOT because Pryde was a bad child (though she certainly can't be described as angelic), but because the Queen's FIRST vision of the condemnation event (which she had while pregnant with Tiara) showed her that Tiara would have precognition. In the Freesia Kingdom, precognition is something that only appears once a generation in the Royal Family, and the child who has precognition is automatically made heir apparent.
All of your other complaints about the Queen being neglectful are completely valid, please carry on. Was only commenting for accuracy.
the queen neglected pryde and tried justifying it as for the country's future. not showing her affection because she would 100% see herself as queen? wtf was the point? that makes zero f*cking sense. neglect is a form of abuse. idgaf about the reason it literally could've caused childhood trauma for pryde. she was a child. she obviously would grow up to be a brat if you treat her like a mere citizen and not family. you caused that because you didn't try to do anything. hiding her sister from her as a back up plan without trying to change anything caused the future you saw. now you're spouting bs and lame excuses because you know you f*cked up and everything you did was useless but you can't even admit that. now you're crying in front of her dad because you're a horrible parent and a stupid queen? choke on your tears in your pity party, b*tch.
