Shen Ruoyu, the daughter-in-law of a former official, was scorned by her husband's family because she could not have children. After she reconciled with her husband, she returned to her unknown hometown of Yunxi Town with her adopted cute daughter "Shen Nuan". She used her only savings to rent an old house facing the street and opened a "Nuan Nuan Snack Shop" specializing in daily snacks. At first, her "outsider" status and "single mother" label attracted criticism and indifference. But a hot dish of scallion oil noodles accidentally attracted a left-behind grandfather who was hard-spoken and soft-hearted. After the grandfather casually ordered it, the noodles tasted amazing. As the news spread, greedy young people who returned home, old ladies who were good at snacks, and others took the initiative to come to the door to "talk" and actually offer help. Everyone changed from "spectators" to "helpers", working together to research and improve snacks, developing "Yunxi Three Flavors" from ordinary tofu puffs, and turning home-cooked dishes into a healing signature. The store's fireworks grew stronger, which not only warmed the hearts of their daughter and Shen Ruoyu, but also united the community. When Shen Ruoyu's ex-husband's family came to persecute and take away the store for commercial interests, the usually gentle neighbors were united as never before. The old people sat at the door of the store, and the young people formed a guard team to guard this fireworks world in the simplest way. In the process, Shen Ruoyu also gradually found his self-worth, and developed a long-lasting relationship with Lu Qingyan, the assistant to the mayor who returned to his hometown, who had been silently supporting him.
