The entire Beijing circle knew that Gu Sihan had married a substitute. Jiang Wan also knew. She thought that when the three years expired, the day Bai Yueguang came back would be her exit. But it wasn't the divorce agreement that knocked on the door, it was Bai Yueguang himself. Lin Wanqing was as thin as a piece of paper. She sat down opposite her and the first words she said were: "Jiang Wan, I'm here to teach you how to be me." She had a terminal illness and would have at most one year left. During this year, she would personally teach this substitute her tone of voice, habits, and small movements - so that Jiang Wan could continue to love Gu Sihan for her after her death. From being wary at the beginning, Jiang Wan gradually realized that this woman who was supposed to be her love rival was lonelier than she was. The two women became the strangest friends on the hospital bed. And Gu Sihan stood outside the door, unable to tell who he loved for the first time.
Concept: A love rival can also be an antidote: you lose yourself and are picked up by your enemy.
