IDK where this will go

Like i think this story is getting more and more far way from any kind of real development. Like, she is older but her mentallity is the same.
If she claimed before that as she was a child and her mental age became young too; it would be understandable that she disregard the second prince. But you can't make a MC so dumb that even as an adult living in that world for some years cannot get a clue at those things.
And I believe the plot where she will trie to just escape the marriage she has been making the ML promisse will be really bad, as she will just be stupid and clueless to anything.

So basically no character development .
