From the "cold winter" when the orphan Jiang Muyue lost her mother, to the "spring day" when she was adopted by her mother's friend Sheng Huaijing, fate sent her to the Sheng family and allowed her to meet the young man who changed her life - Sheng Huaizhi.
When she first entered the Sheng family, Jiang Muyue was timid and uneasy after losing her mother, while Sheng Huaizhi was the uncle who called her "Mumu" and gave her the strawberry cake. He would quietly bring her a rabbit doll to accompany her when she woke up from a nightmare; he would stand in front of her to support her when she was bullied by her classmates; and when she cried in front of old photos of her mother, he would clumsily pat her back and say, "I will protect you from now on." This begins with the protection of family, but ends with the love of love.
