I know Korean authors don't care or research protocol, good manners, and such, but it bothers me to no end the absolute lack of formalities in a period story. I know, sometimes, they want to show how "progressive" their characters are but that's not how being "progressive" works; they should call her Milady always, not Ma'am or any other form (minus the new tiger guy coz he doesn't know), and she should address the governess by a "Mrs. whatever" not her name, not to mention those inappropriate hugs.
