When Segyeong 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. Segyeong’s best friend, Choi Ahjeong, helps her to find out the life of Seo Yoonjoo in order to know how to become a “Cheongdam-dong daughter-in-law”. She finds out that Yoonjoo actually is called Cha Yoonjoo when she has lived in France because she has married a man there. Segyeong guessed from this information and the words of Shin Minhyeok, who is the president of GN Fashion, that she is accepted specially by Yoonjoo.
