On the campus of Sunshine Middle School, stories of youth are staged every day. Lin Xiao, Su Ran, Chen Yu and Zhao Yang, these four young people with very different personalities, are writing their own chapters of youth in their own way.
Lin Xiao is a girl with excellent grades and a reserved personality. In her world, books are her best friends. Every morning, when the first ray of sunshine shines into the campus, Lin Xiao will always sit in the corner of the classroom, quietly previewing the day's lessons. Her eyes were focused, as if the whole world contained only the knowledge in books. Su Ran is completely different from her. Su Ran is lively and cheerful, like a little sun, always bringing happiness to people around her. She loves painting, and the picture album she carries with her is filled with paintings of every plant and tree on campus, as well as the vivid looks of her classmates.
Chen Yu is a basketball expert. His heroic appearance on the court has attracted the attention of many girls. In every basketball game, he is like a shining star, leading the team to charge. Zhao Yang is a literary young man who loves poetry and often recites his own poems softly in the campus garden.
