Thanh Mai advises Nhu Y to focus on learning how to make ao dai but she neglects, because she only likes Western style. One day, Thanh Mai uses a unique piece of fabric passed down from her ancestor, to make a beautiful ao dai. Nhu Y sees it (due to her name is embroidered on that ao dai) and decides to try it on. Strange thing happens as soon as she tries it, the piece of jade sends her to the year of 2017. Nhu Y falls on An Khanh (as Nhu Y in 2017) as she is about to attempt suicide, causing the piece of jade to detach from the ao dai. Nhu Y is shocked to know that the tailor house Thanh Nu has been closed and barely believes that An Khanh is her in the future, and how Sai Gon has become greatly modernized. Her house is empty and quiet. It's revealed that after Thanh Mai had died, Thanh Loan was told to leave the house by An Khanh so An Khanh could open a Western tailor house, however the business failed shortly afterward. This causes An Khanh to become an alcoholic. Thanh Loan opened her own business mainly focusing on tailoring ao dai, she later has two kids: Helen and Tuan. Helen is a famous fashion designer while Tuan is working at Helen's company. Helen agrees to help An Khanh keep the house, however Nhu Y must work for her in exchange. Nhu Y works as a cleaner while Tuan helps her adapt to modern life. The company needs some 1960s inspired designs which is An Khanh's specialty so she helps Helen. Being impressed by Nhu Y's talent, Helen assigns her to ao dai designing. This is her big challenge since she has always hated ao dai and doesn't know how to do that. At the same time, she would like to tailor ao dai following Thanh Nu's traditional way, which will help Thanh Nu regain its reputation. An Khanh meets Thanh Loan in order to apologize and ask Thanh Loan how to tailor ao dai properly. Later, Thanh Loan gives An Khanh an envelope which is the letter from Thanh Mai attaching ao dai tailoring method. An Khanh and Nhu Y together practice on how to make ao dai. In the fashion event, model Trang Ngo and many models wear Nhu Y's collection on the catwalk.
