Su Nian was once the world's top hacker "Athena". In order to escape the past, she retreated into the world and only wanted peace and quiet. In order to cope with her family, she was matched with Gu Yan, the president of Shengyu Group, through the national "AI Yue Lao" system - a rational and rigid "unsaleable president" with E-level social skills. The two signed a one-year contract marriage and agreed not to disturb each other.
However, his cousin's provocation at a family dinner unexpectedly exposed Su Nian's true strength. From network security attack and defense to the exploration of abandoned factories, to the dock confrontation and the decisive battle in the underground air-raid shelter, the two were forced to join forces to uncover a shocking conspiracy involving the "Patron Saint" of the global surveillance system, the capital giant "Pan Rock" and the mysterious organization "Shepherd". Only then did Su Nian learn that he was the only "key" to the ultimate security protocol "Prometheus Fire" left behind by his mentor.
In the test of life and death, Bingshan CEO Gu Yan went from scrutiny to trust, and finally firmly guarded: "Your trouble is my trouble." The two grew from a contracted couple to life and death comrades and soul mates, working together to destroy the dark forces and protect the light of the digital world.
At the end of one year, they did not divorce, but held a real wedding at the seaside. Now, she is his wife who fights side by side, and the mother whose eyes shine in his daughter's eyes - under a peaceful life, they are each other's strongest fortress and warmest light.
