Chae Mu-Ryong (Jae Hee) 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 because 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 chef's 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 a car accident, coincidentally with Yoo Hee. They exchange insurance information and Yoo Hee learns that he lied to her on their date, realizing that he is 1 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-Ryongs 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.Johnny Kruger (Dennis Oh), is a famous French Chef from New York. He despises that his stardom overshadows his cooking and concentrates only on his cooking in Korea. Yoo Hee and Johnny are close friends from way back but thanks to Mu-Ryong, Johnny is now considering the possibility of having a deeper relationship with Yoo Hee but will he succeed?
Yoo Joon Ha (Kim Jung Hoon) is an ambitious surgeon with whom Ma Yoo Hee has been in love with for a long time. Yoo Joon Ha is a cold-hearted character who is capable of betraying his most precious love for success. Though he is an ambitious two-faced character, he is a bad guy in the sense that his weakness stems from his strong desire for success.
Nam Sung Mi (Jeon Hye Bin) is the beautiful, kind, clever and ernest girlfriend of Chae Moo Ryong who, unlike Ma Yoo Hee, puts marriage in the first place. Nam Sung Mi is placed in this situation where she has to compete for the attention of his man with his work and his personal relationship with his boss Yoo Hee.
