I like the concept, theoretically, but I'm not sure it works. Leticia Astarl is a disrespectful tomboy who's undergone a decade's worth of "princess lessons" in order to marry Prince Clarke. She wants to: (a) ditch Clarke, and (b) run away. From anything, at all times. She likes freedom, fishing and doing what she wants.
In principle, this is amusing. In practice, it's one-note. Instead of having goals, she's always just trying to run away. The action is the objective. Does she think anything through? Nope. What's in her head is ill-defined and, frankly, she's a bit of an idiot. Furthermore, we know the story's endpoint. Clarke is a nice guy who's devoted to Leticia and will never stop following her, while Leticia's reasons for rejecting him are superficial ones like "I'm grumpy about princess lessons". Will she overcome her own empty-headedness? Eventually, in time, if you stick around. "Predictable" can be charming in romance series, but this is the wrong kind of "predictable" because it equals "what a moron".
Sometimes I laughed, though. Leticia's shamelessness can be amusing, while I liked her relationship with a ruthless girl who agrees with her on the relative priorities of avoiding princess lessons (high) and marrying princes (lots of reasons to decline). I also liked episode 5. Leticia gets kidnapped, but her abductors are pathetic and soon she's being magnificently condescending to them.
"At any rate, it's clear to me that Prince Louis is a sad little boy indulging in a completely one-sided infatuation."
"Don't call me a little boy!"
"Oh, pardon me. I suppose you're at the age when you try to act all grown-up."
Leticia gets a clue about Clarke about halfway through the series, but that doesn't stop her escape efforts. This is dead effort. We know she'll get recaptured, because that's the story formula. We know her motivations are shallow and that her escape attempts wouldn't achieve anything if they succeeded. Yeah, sure, she dislikes the lessons. Understood. Her teacher is a harridan. (If you become queen, though, couldn't you get your husband to hire a friendlier replacement?)
One oddity is that Leticia narrates her own adventures, sometimes in asides to camera. I'm reminded of Restoration comedy. That also fits the story's tone, setting and subject matter, with the main mismatch being the costumes. They're from a slightly later English historical period, I think. Less foppish and with even more amazing dresses.
I don't dislike this show. It can definitely be funny, e.g. Leticia's pitch when trying to sell her brother as a potential love interest. However, it's a light, slightly aimless show where episodes can be resolved by "it was all a big misunderstanding!" You could improve the series by cutting half of it.
