Working-girl Mu Xiaonuo, in order to make money to support her family, accidentally gets hired as a nanny for the blind and irritable Fu Yunjing. Facing Fu Yunjing's every resistance and expulsion, Mu Xiaonuo relies on her superhuman strength and optimistic personality, not only successfully getting Fu Yunjing, who resists eating, to drink chicken soup, but also seeing through his fragile side—afraid of the dark and lacking a sense of security beneath his irritable shell—during their interactions. The two gradually close the distance in their chaotic and lively daily routine, starting a cohabiting story full of dense comedic moments and warmth.
