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. Now that they're dating, Choko and Masayuki go on their first overnight trip together. Will the two be able to add to their relationship a new role--that of lovers?
