Screenwriter Chen Chen was punished by an unknown system because he complained that the plot of his parents' idol drama "Mischief Kiss" was too old-fashioned. He was thrown into the drama "Mischief Kiss" to replace the heroine Yuan Xiangqin to complete the plot. He could not change the direction of the story, otherwise he would never return to real life. But during the process of traveling through the drama, a series of incredible things happened. The cherry blossom earrings he had before traveling through time were actually in Jiang Naoshu's hands? Jiang Naoshu actually knows the real her? Did you also know that she came from time travel? Does the space-time paradox really exist?
