Dr. Ranz Liam Acozta is the most strict person you'll ever meet when it comes to work. He doesn't want to repeat his words. Once is enough. If you make just a single mistake then it's either you get fired or just quit the job. You choose? Because if you try to stay, then you will be experiencing hell under his command. He is not the type of person who can easily forget. So he will do anything just to get rid of you. Now, who's willing to work with him? Of course there is someone. She may not be smartest, but she can definitely make him shut up in just a snap. If Dr. Ranz is very strict boss, then his maid is a brat.
