Zeng Yichen, the top second-generation rich man in Beijing, appears to be a playboy who enjoys eating, drinking, and having fun, but in fact he is a secret agent of the country's "Script Office." This mysterious organization specializes in "brushing" disaster scripts from parallel worlds and saving the real world by predicting them in advance.
When Zeng Yichen came across a script called "The Jealousy Lord", he encountered the biggest trouble ever - the villain in the script, the Jealousy Lord, turned out to be himself. It turns out that he always thought he was the hero who saved the world, but he didn't know that his jealousy had swallowed up reality and turned into the destroyer of the parallel universe.
What's even more terrifying is that when he meets a girl named Lin Ruoxi in the real world, she is the last survivor of the world he destroyed in the script. Her true identity is a time traveler, and her mission is to prevent Zeng Yichen from becoming a demon.
Now, the future demon lord and the time traveler have become college classmates, and neither of them knows the other's true identity. One wants to save the world, the other wants to protect himself. This drama of falling in love and killing each other is far more exciting than any script.
What Zeng Yichen didn't know was that every move he made was being broadcast live by a higher-dimensional being - "Everyone, please enjoy this reality show that will determine the fate of three universes."
