In the 1920s, in a beautiful world, Jiang Jiwei, a bank clerk, and Hong Xinxin, a little Hua Dan of the troupe, both longed for a beautiful marriage day and night. I met by chance when I was looking for a marriage in Yuelao Temple, but the two sides got stuck in the wrong door because of a little misunderstanding and hated each other. Yan Yan has a crush on the shrimp under her skirt in class, but there is no emotional reaction. But Zhang Xiaoying, who looks pure and sacred, is Jiang Qiwei's dream lover. Because of this, Ji Wei launched a series of blind pursuits for Xiaoying.

Two weeks later, when the troupe returned from its tour, Xinxin found that the newspaper had published the news that Jiang Jiwei had died. More curious, she saw the ghost of Ji Wei appear. It turned out that Jiwei was killed by Xiaoying because she loved Xiaoying, and conspired with Yan Luowang. After Ji Wei's death, he possessed wires, and Yan Yan inadvertently led Ji Wei to appear. Ji Wei secretly followed Xin Xin to help him return to the dead, and returned to the day of the crime, which changed the fact that Ji Wei was dead. Yan Yan didn't want to, but she was entangled by Ji Wei and finally reluctantly agreed.

In the process of going back in time, the two changed from mutual hatred to mutual understanding, even at the expense of each other, but they had to face great resistance to change history. Finally, they fell in love and showed their true feelings. Two people touched their real selves with their true feelings, and four people killed Yan Luowang together, which prevented the tragedy from happening, and the real Yan Yan and Vicky also started their real love. After changing history, the future Yan Xin and the ghost Wei Wei will disappear. Before they disappeared, they were sure that no couple in the world would know each other better than they did. But the fact is the fact after all, and the two eventually went away.
