In the highly technologically advanced "Xinglan City", Lin Xiaoman, a programmer who is socially fearful and fond of brainstorming, unexpectedly received a strange order from the "cloud". Not only did the other party accurately point out the "hidden bugs" in her code, he was always able to "rescue her from a distance" when she fell into trouble in life. As the contacts increased, Lin Xiaoman discovered that this mysterious "cloud client" was actually his neighbor who had just moved in - Jiang Xubai, an AI engineer with a cold appearance and a sultry heart. The two became connected because of the AI project, from "mutual hostility" online to "mutual assistance" offline. They gradually broke down the barriers while solving a series of wonderful AI-related events (such as the collective "rebellion" of smart home appliances and the case of missing AI pets). Lin Xiaoman used her "brain hole" to bring new inspiration to Jiang Xubai's AI project, while Jiang Xubai helped Lin Xiaoman overcome his social fear. In the end, the two not only completed an AI product that shocked the industry, but also gained a sweet love, which perfectly interpreted "no matter how cold technology is, it cannot match the warmth of the human heart."
