If this is not being presented as "Comedy", this would just simply be a glorified romanticization of kidnapping, with a forcefully applied 'Stockholm Syndrome'.
If there's a girl who's forced into a life she didn't want and future marriage she didn't choose for herself, you'd think that the man who she is forced to marry, who seem to really like her a lot for her free spirit nature, would be the very first person to help her get that freedom, right?
Well, in this story, the prince likes the FMC so much that he would be so persistent in making her marry him, promising to make her happy and giving her everything she wants... by forcefully taking the freedom she's been wanting to regain for a looong while, which make her veeery happy, imprisoning her in the royal mansion himself until she submits.
So basically, this guy refuses to court her properly by convincing her that he can give her that free life she wants, and instead just forces himself to her, limiting her options to either learn to love him... or just simply be forced to marry him.
And considering her family is quite supportive of all this, we can throw slavery into this as well, with her basically being sold to a royal family at a very young age.
There's a limit to what counts as a humorous Anime take on a realistically problematic situations and behaviors, and this one ain't it.
As much as I want to laugh at the little comical escape the princess does, I just can't see it as 'funny' when every time she gets caught, she reacts more like an actual prisoner who desperately begs to be freed than a comical character whose plans just got thwarted for the hundredth time.
Overall, this is just a 'Cat and Mouse' Rom-Com with a premise so horrible you won't feel like laughing.
----------------
In an attempt to end this with a little positivity, I'd say that much younger audiences would likely not notice those aforementioned premise issues and just simply enjoy it as a cute Rom-Com show ("Ignorance is bliss" as the saying goes). Production quality is also pretty good.
I also appreciated the dynamic of the FMC with her brother and her servant. Their little banters provided some fun, for what it's worth.
