In the urban forest of steel and concrete, Wang Xiaoxiao, a post-95s girl, with the dream of "let every child have a childhood home", resolutely quit her high-paying job in a major Internet company and took over a community kindergarten that was on the verge of bankruptcy. Facing the doubts of parents, the crisis of broken capital chain, and the various "little troubles" of children, she is like a tenacious sunflower, working hard to bloom in the wind and rain. Her friend Liu Yue, an experienced preschool teacher, has always been her strongest support. The two worked together to renovate the dilapidated campus, design special courses, and resolve crisis after crisis with patience and creativity. When kindergarten gradually became a paradise for children, Wang Xiaoxiao discovered that she had to protect not only the children's childhood, but also the original intention and warmth that adults had gradually lost in the city.
