Business tycoon Li Mochen has an irreplaceable woman in his heart. To ease his longing, he finds Su Wan, an orphan who bears a striking resemblance to her, and signs a three-year contract for her to be her substitute. Su Wan loves him humbly and tries hard to play the perfect replacement. But after an unexpected pregnancy, she realizes she can never take the woman's place in his heart. In her despair, she discovers a shocking secret about her own identity. Heartbroken, she stages a flawless "death" and leaves for a distant land with the child in her womb.
Five years later, Su Wan returns in triumph as Wan, an internationally renowned jewelry designer, with a gifted child in tow. She only wants to leave the past behind and begin a new life, but she cannot avoid crossing paths again with her powerful ex-husband, Li Mochen. When Li Mochen sees the child who looks just like him and learns the truth behind her supposed "death," regret and long-delayed love engulf him like a tidal wave. He casts aside all pride and launches into a frenzied campaign to win his wife back. But the Su Wan who has returned is no longer the substitute who could be pushed around. She shines brilliantly, and a gentle second male lead stands devotedly by her side. Li Mochen must face not only Su Wan's coldness and rejection, but also unravel the misunderstandings and schemes that drove them apart, compete with the rival watching him closely, and learn how to become a true father. This is the ultimate struggle over love, dignity, redemption, and growth.
