Cha Seung-jo, French name Jan Thierry Cha, is the youngest Korean president of a famous luxury brand called Artemis. He believes that women go after luxury brands because of their high prices. His strategy for management is to raise the price of products to achieve increased sales. Han Se-kyung is a person who tries her best in getting everything and lives by the motto of “Self-achievement generated from hard working”. Though she studies design, because of her family’s financial problem, she doesn’t have the opportunity to study design abroad. And for this reason, not having any abroad studying experiences, she is often rejected by job interviewers. After three years, surprisingly, she is offered a job as a temporary worker at a clothes designing company called GN Fashion. She doesn’t become a designer in the company; she becomes an errand girl for the head lady. When she is delivering some bags once, she bumps into Cha Seung-jo’s car.

When Han Se-kyung is about to quit her job, her team leader tells her that the reason she can’t become a designer is that she doesn’t have the taste for fashion, leading her to reconsider her decision. Han Se-kyung’s best friend, Choi Ah-jung, helps her to find out the life of Seo Yoon-joo in order to know how to become a “Cheongdam-dong daughter-in-law”. She finds out that Seo Yoon-joo actually is called Cha Yoon-joo when she has lived in France because she has married a man there. Han Se-kyung guessed from this information and the words of Shin Min-hyuk, who is the president of GN Fashion, that she is accepted specially by Seo Yoon-joo.

Seo Yoon-joo asks her brother, Seo Ho-min, to stalk Han Se-kyung secretly. From the pictures taken by Seo Ho-min of Han Se-kyung, she sees Cha Seung-jo is in it. On the other hand, Cha Seung-jo’s doctor/best friend, Heo Dong-wook, says Cha Seung-jo cannot control his emotions mentally, he can never cry. Secretary moon finds Seo In-chan’s location; he is at his mom’s funeral at the time. Cha Seung-jo happens to witness the scene and he orders the company not to go after So In-chan anymore. Instead, he sends flowers to the funeral house to express his sorrow for his mother. Under the warning of his father that someone is secretly taking pictures of him, he catches Seo Ho-min and warns him not ever to do it again. Cha Seung-jo also moves to the same neighborhood where Seo Yoon-joo is living.

Seo Yoon-joo tells Han Se-kyung that in order to go into Cheongdam–dong , she must find herself a “time rabbit” (a person who can introduce her into the upper class circle of Cheongdam-dong). Tommy Hong, the most popular domestic designer in Cheongdam-dong, is the perfect fit for being the “time rabbit”. So Han Se-kyung then decides to part time work at the restaurant where Tommy Hong usually goes to in order to catch his attention. Meanwhile, Cha Seung-jo, full of tears, tells Heo Dong-wook what he has seen about Han Se-kyung. Heo Dong-wook tells Cha Seung-jo that he thinks he might like Han Se-kyung. Back when Seo Yoon-joo has wounded Cha Seung-jo deeply by leaving him, he changes. He tries to find a way that true love exist, that it does not need to be only maintained through money. Han Se-kyung’s actions makes him believes that love truly does exists, proving that his thoughts are right. He then recommends Han Se-kyung to Tommy Hong.

Han Se-kyung is not willing to give up her “time rabbit” after what has happened at the ball. She goes to Tommy Hong to reason with him. But instead, Tommy Hong sees her desire, what she wants in her heart. Seo Yoon-joo goes to see Tommy Hong; she learns that the person who he is trying to pair up with her husband’s sister, Shin In-hwa, is actually Cha Seung-jo.
