The story tells the story of Ji Shu (Zhu Zhengting), the author of sadomasochistic novels, and Song Yanqi (Lu Yuxiao), a film and television planner who loves perfect love. The two accidentally traveled into Ji Shu's novel and rewrote the plot. In the process of rewriting the novel, the two continued to grow and injected warm blood into the novel. The male protagonist Ji Shu suffers from emotional indifference and is also an extreme pessimistic writer. His novels fully implement his pessimistic thoughts and all end in tragedy. Song Yanqi, a film and television planner who has been a "last train koi" since childhood, is just the opposite. He is a fan of a perfect ending. When the pessimistic novelist meets the optimistic film and television planner, the competition between the two in the real world extends to the tug of war in the novel world. Song Yanqi is dissatisfied with the direction of Ji Shu's novel story. By chance, the two opened the mysterious passage between the two worlds of novels and reality, and thus began the tug-of-war between the two about "HE" and "BE". In this rewriting game, who will win the initiative?
