There is a wet nurse, a wet nurse, and a beauty born in the 90s; the father takes his son alone, and the wet nurse takes her daughter alone; after a small car accident, the two met by chance, but they did not know that they were working partners. The beauty born in the 1990s fell in love with the nanny at first sight, and the nanny, who was alone with her daughter, also developed a tacit understanding with the nanny as they got along day by day. So, where will the nanny go? The nanny's buddy is a typical "marriage phobia" person, but the nanny's best friend is a staunch bachelor; will there be any intersection between them? The development of the story begins when the two children go to kindergarten on the first day ------
