Lu Kun, chairman of the 'emu' technology company, suffers from a rare illness. When he touches a person, he suffers an allergic reaction. It happened that genius Dr. Bo Yang secretly created the intelligent companion robot "Friday". At the last minute, Dr. Fu Yang was forced to hire his former assistant Yang Shan Shan to replace "Friday". Because Yang Shan Shan played "Friday", Lu Kun had an infinite sense of security. He found that as long as "Friday" is present, he can come into contact with humans and no longer be allergic. This discovery made him even more inseparable from "Friday". Lu Kun's warmth and innocence and love for "Friday" gradually broke Yang Shan Shan's heart. Knowing that deception may cause Lu Kun's illness to worsen or even die, Yang Shan Shan had to bury the truth about not being a robot.
