This is a story about growing up. Lin Ruixue was born in a well-educated family in the 1990s. Growing up under the restrained whipping and exhaustive care of her parents, she has always lived a happy and simple life. Because she went to school early, she was always two years younger than her classmates, and she was under heavy academic pressure at a young age. After entering Siyuan High School, Lin Ruixue overcame various difficulties with the help of Fengnian Yi and Ren Hongzhi, and gradually made a group of good friends. High school is a critical stage of growth in life. Siyuan witnessed every happy, sad, sweet, sour, surprising, lost and even angry moment of Lin Ruixue. After tasting the bitter, spicy, sour and sweet flavors, Lin Ruixue began to thrive like a pruned sapling, striving for a good start in her life.
