Yeap. here is the link: https://www.novelupdates.com/series/suddenly-became-a-princess-one-day/
But well, some time ago I heard that the translation of the manhwa adaptation was further ahead than the novel translation. Thought, since I didn't check it myself, I don't really know.
I checked the link you've posted but it says translation is in Korean. Is there an English translation? Please help.
Novel Updates is a forum with only English translations. I checked the first chapter, just to be sure, and it's definitely in English (you probably got confused by the details of the description, as they put the original language and the type of adaptation).
Anyway, I'm going to link you to the first chapter I found there.

You'll find the other chapters on this same site, probably.
if yes then plz link me up! you kind soul!
