Ma Yoo-hee is the executive of an advertising company. She would never be caught dead wearing make-up and only ever wears black. Her hairstyle and glasses are severe, her only enjoyment in life appears to be the times when she’s criticizing everything and anyone. All of her employees and co-workers fear her and she is constantly talked about when shes not around. Her stern and harsh nature has earned her the nickname ‘witch’ When it comes to romance she is hopeless. No matter how many blind dates she has, not one has ever led to a second. The reason for this is her negativity and her inability to loosen up and express herself. She however is completely oblivious of her faults and cannot comprehend why she is so bad when it comes to love.
Choi Mu-ryong is an aspiring chef with a passion for French cuisine. He has an innate ability when it comes to taste and perfection. Every piece of food and every plate he prepares must be perfect. However this tends to get him into a lot of trouble as when working in a kitchen every moment counts and there is not possibly enough time to take so much care in preparation and decoration of meals. His criticism of a head chefs cooking causes him to lose his job. His parents have never really approved of his aspirations and dreams to be a famous chef and insist he return to medical school. He decides to enroll back into medical school but changes his mind at the last minute and decides not to.
Mu-ryong discusses everything with his best friend and ends up going on a blind date to pretend to be someone else who backed out at the last minute. He declines at first since he already has a girlfriend, but his friend offers him money, and warns him however that the woman he will be meeting is rather different.
The woman he meets is Yoo-hee, and while under normal circumstances she would be rude, brash and boring, she tries to be nice and happy in an attempt to succeed on the date. However, her pretending is not very convincing and Mu-ryong figures that it would be a matter of time before she loses it. The date ends when Mu-ryong falls asleep for a moment, resulting in Yoo-hee throwing a glass of water at his face and calling him rude. He retorts back to her also, telling her to take care of her appearance the next time she goes on a blind date. The two then leave on bad terms.
While delivering food from his father’s Chinese restaurant, Mu-ryong becomes involved in an car accident, coincidentally with Yoo-hee. They exchange insurance information and Yoo-hee learns that he lied to her on their date, realizing that his name is different, he is a year younger than her, and that he met her only as a favor to a friend.
Yoo-hee demands the money for the damage to her car to be paid within a week. However, Mu-ryong doesn’t have any money, and yet Yoo-hee is unwilling to compromise with him. He decides to use his school tuition, which was given to him by his parents, to pay for her car. However, he loses the money after being mugged on the way to pay her.
Mu-ryong tells Yoo-hee he doesn’t have the money but is willing to work it off, no matter how long it takes or what he must do for her to pay her back. Yoo-hee decides that Mu-ryong could repay her by working as her house keeper, since she continuously looses her previous keepers.
Meanwhile, Mu-ryong’s girlfriend Seung-mi, who works at her father’s restaurant, is expecting a new head chef: Johnny Kruger, a world renowned chef, who also happens to be Mu-ryong’s idol and an acquaintance of Yoo-hee as well.
