Twenty-year-old Ye Zhixia, mocked by classmates for her figure and locked in constant conflict with her mother Cheng Yun, is sent away to live in the mountains for a hundred days. Under Grandma Zhou's strict demands and Chen Xiaoman's sincere companionship, she transforms from resisting laboring to learning how to pick oranges, cook, dry tangerine peel, and even trying to sell oranges via short videos. Her increasingly regular routine helps her regain confidence, and mother and daughter finally communicate honestly. Returning to the city, she calmly faces her former classmates, reorganizes her life, and finally returns to the mountains to visit Grandma Zhou.
