Everyone will have light-colored memories of that special period in their hearts, whether they are sweet, bitter, or ordinary. What is told here is the story of a girl, Li Mufei, who grew up from being ignorant about love in high school to understanding love and marriage. Maybe this story can bring back memories of that period for you. It's like the fragrance of sycamore flowers in memories, the breath of summer in memories, the scene of you and your first love walking shyly on the beach with bare feet. But the most important thing is that maybe you can find the traces of your own growth in Li Mufei's growth.
