Choko Kuze is the sensible daughter of a venerable family who went bankrupt. She joins a real estate company as an entry-level office worker, but her eccentric boss is harder on her than anyone else in the company! After hearing him inadvertently call her milady, she realizes he was the young servant boy she knew as a child. At work he's a tyrant, but after hours he insists on treating her like a lady of the nobility. Is romance even possible for a couple locked in such a crazy role reversal?

Choko Kuze is in love with her ex-servant-now-tyrannical-boss Masayuki Domoto. She's had a hard time getting him to see her as a woman, but between bouts of treating her like a genteel lady and an entry-level office grunt, he's slowly starting to come around. Unfortunately, the CEO's niece has set her sights on Masayuki and won't take no for an answer. Will Choko step aside to protect Masayuki's career, or is it now time for her to pull rank?
