This is like the reject version of Quickly Wear The Face of the Devil.
Maybe I've been spoiled by the good writing, characterization, and translating quality of QWFD.
More like, given how the premise begins, it's incredibly unlikely I'll care about the character. I have no idea about his motives or what rules he has to abide by in order to escape the system before the story dumps you into a world that the MC has already lived before. The lack of clarity drives me to not want to read this story after the first chapter.
I'm also the type of reader who gets annoyed at being bombarded with translator comments in between what I read. Maybe you like it? Maybe you don't. But consider yourself warned that they'll be there.
I hope I'm wrong about my assumption but I'll wait until a couple more chapters are translated to really assess.
This was the first novel page I've seen with such an even spread of votes four stars and under. But it makes sense after reading the novel. Instead of having a System that's a tool to jump dimensions or give helpful tidbits, it's basically a convenient plot device to explain why the MC, who was bedridden and from a different world, was suddenly healthy... and in a different world. If you take out those factors this is really a female male 1v1 HE story. It seems like the author was attempting to add new interesting elements to what would be a typical romance story. Except those factors don't change the overall outcome. Basically, a female MC supporting the male lead but with an "enforced" reason. (That isn't really enforced as you have no idea what punishment she would face if she didn't follow what the system indicates. Automatically given circumstances? Eh.) As long as you don't expect the level of plot and character development as FoD and take this more like a romance novel, this could be for you.
On a side note, the translation quality is decent but if you're like me and get annoyed at weird things in text while reading, just know there's going to be alternate bold paragraphs. Not as distracting as translator notes but distracting nonetheless.
Of course there were princess that revoked or removed themselves from royal lineage but this doesn't apply to Lucia. She has no support from her father, no one to teach her the rules or powers she has as a (pseudo) princess. She grew up as a Commoner and her dream-future husband certainly didn't help with educating her on these aspects. How would Lucia be capable of going to the king and asking for those privileges? With no support or anyone, not even the general servants in the castle know about her, how could she get an audience with the king to even ask for those things?
I agree with the point about her "sleeping beauty" ideology but I don't believe that she expected her father or half brother to be generous to her future marriage. It's why she eventually came to the circumstances of clumsily seeking marriage with the male lead.
And as a final note, cliche as this sounds, this is a work of fiction. The author didn't claim this novel to represent a realistic historical narrative. There isn't a need for the novel to lend itself to historical accuracy.
