Oh, it is that kind of manga. What is it called "Prince X Tough girl" or something? (Tough girl is a poor description, but can't think of a better word.)
There's that old high-school maid manga if someone here likes this one, and somewhere in the land of the unupdated there's also one with a girl who is accidentally the greatest Casanova ever, and her tsundere prince.
Note that this doesn't mean that this manga is bad or anything, but it is a common setup (for good reason) so I suspect there's going to be a feeling of déjà vu when reading it.
