Jewelry designer Wen Nuo is forced to become the contract bride of business tycoon Lu Tingshen, replacing her twin sister Wen Ya who escaped from marriage. In this marriage that existed in name only, she abided by her duties but was repeatedly indifferent and tempted by Lu Tingshen. When Wen Ya returned to take back everything, Lu Tingshen found that he had already fallen in love with the stand-in who drew design drafts late at night and made sweet-scented osmanthus cake for his grandma. And Wennuo's identity that has been hidden for many years gradually comes to light - she is the girl who saved him back then, and she is also the mysterious designer "Eileen" in the international jewelry industry. Faced with the truth and conspiracy, Lu Tingshen embarks on a journey to pursue his wife's crematorium, while Wen Nuo faces the final choice: to be someone else's shadow, or to find his own life?
