Smells like bad news
(If you spoil this for me, I will actually flip you inside out)

Yes there is a novel ,my guess is the original source is complete but the English translation has yet to be completed. (/TДT)/
I read it from wattpad, if your type the manhwa's title you should find it though it is not complete, there is also another one that takes place right at the moment Claude loses his memories and after, the person who posts has not completed it either but it goes way beyond what we have currently and even more than that. Σ(っ°Д °;)っ
I will provide the links below this comment if you are interested in reading I will provide the links to both the places I read it from.(๑•ㅂ•)و✧

Here are the links, if they do not work please let me know and I will try to provide the correct links.(๑•ㅂ•)و✧

I made a mistake with the first link for this hopefully this should take you to suddenly became a princess novel, this one starts at the beginning, it is not completed yet but do see a lot of what we have already and along with some extra details which were cut out.
If this link does not take you directly to the novel, just go on wattpad and type Suddenly Became a Princess one Day and it should be on the top.

Have I mentioned how much I love her as a character?
She's a super tall, badass lady, who is still elegant, and loving to the people who are closest to her, and someone who will not allow herself to be stepped on.
She's such a well-designed character, the author could've just made her some tiny Dame, with a tiny little scar on her face -- but no, the author made her distinct, and unique, the same with her husband, and that goes beyond just their design, but also into their personalities.
As much as I love Leslie, I feel like when we're fangirling/boying/othering, we just focus on Leslie (very understandable, I'm not blaming you for anything, she's a precious little bean), but we neglect some of the other characters that deserve some of that excitement too.
And they don't even know it --
This is gold!
Gold, I tell you!
