When Se-gyung 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. Se-gyung’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 Yoon-joo actually is called Cha Yoon-joo when she has lived in France because she has married a man there. Se-gyung guessed from this information and the words of Shin Min-hyuk, who is the president of GN Fashion, that she is accepted specially by Yoon-joo.
