Cao Yang is an extremely ordinary worker in a technology company. His biggest hobbies are repairing computers for neighbors, picking up couriers for colleagues, and finding homes for stray cats - a typical "dog-type warm man" who cares deeply about people.
One day, he found a dilapidated simulation robot in a recycling bin and took it home to repair it out of kindness. Unexpectedly, this robot not only has super-advanced artificial intelligence, but is also bound to a weird "favorability system" - as long as Cao Yang is good to others, he can unlock various black technology rewards. What's even more outrageous is that the robot claims to be his "fiancée" and refuses to leave. It is always jealous and sabotaging, turning Cao Yang's originally peaceful life upside down.
When Cao Yang thought this was just a difficult "electronic girlfriend", a series of mysterious events followed: a rival company suddenly mastered advanced technology, the laboratory was stolen, and someone was secretly monitoring... He gradually discovered that the identity of this robot was far more complicated than he imagined, and her existence was quietly involved in a conspiracy concerning the future of the entire human race.
On one side is the sweet daily life, on the other side is the thrilling technological secret war. Can Cao Yang handle this jealous robot girlfriend?
