Princess is written like the comidec relief from a Disney movie neither me nor my wife could take her character seriously like if Fiona from Shrek lost all everything that made her awesome and turned her into I fight for freedom even if that freedom costs the lives several dozens of citizens. (On one point my wife came up with a better idea to get the kingdom and rule in 3 steps)
Step 1: marry prince
Step 2: make an heir to the kingdom (son)
Step 3: poison king and leave kingdom to heir while you stay in power cause your it's mom
