Duan Yu, a 26-year-old single mother, had a crush on her neighbor Wang Yuyan for twenty years and dared not confess her love. She was finally dragged into pretending to be her boyfriend, but ended up being killed by a dump truck in order to save a little girl. Three souls were separated, one soul was hung up on Wang Yuyan as a navigation, one soul was stuffed into the body of a sparrow to experience bird life, and the other soul was taken into a magic weapon by a cult old man as a power bank. Since then, the city's criminal investigation detachment has gained a policewoman who relies on "bird singing" to solve crimes, and there has been a chatty sparrow in the sky above City A. Solve the case, slap someone in the face, catch the mole, clean up the den, and fall in love by the way. Finally, the three souls returned to their places. Duan Yu sat up from the ICU and said the first thing he said: "You just said you will never forgive me in this life. Does it count?"
