Lu Zhixing suffers from recurring hereditary diseases. His grandfather recalls a secret formula from Mr. Shengxu ten years ago, and despite Lu Zhixing's resistance, he decides to try it. Shen Zhiyi is brought back by the Shen family and forced to marry into the Gu family in place of Shen Yao. She rebels and questions Gu Tianyao, the young master of the Gu family, accidentally mentioning a marriage agreement with the Lu family. Lu Zhixing, following the formula, finds Shen Zhiyi, and the two have a whirlwind marriage. The two clash in various ways, and Lu Zhixing is gradually attracted to Shen Zhiyi's straightforwardness and talent. Shen Yao, consumed by jealousy, lies about having an affair with Lu Zhixing and faking a pregnancy, attempting to force him to divorce. Shen Zhiyi believes her and leaves after proposing a divorce. After Shen Zhiyi leaves, Lu Zhixing's condition worsens, and he falls into a coma. His grandfather asks Zhou Yifei to treat him, and the treatment is successful. Lu Zhixing also discovers the truth, and the Shen family declines due to the scandal. Mr. Shengxu appears to test their relationship. Lu Zhixing kneels and begs for his blessing, and Shen Zhiyi confesses her pregnancy. Mr. Shengxu reveals the truth of "worldly cultivation"—hoping she finds happiness—and ultimately approves of their relationship. Shen Zhiyi fulfilled her mother's long-cherished wish by burying her parents together; Lu Zhixing and Shen Zhiyi lived happily in the Lu family home, beginning a new chapter in their lives.
