So Young(2022)

So Young is a Chinese series following An Jing, a senior student in the small town of Songxi who writes a school novel called "Goodbye, Seventeen." As she develops three interconnected stories through her protagonists—An Na, An Qi, and An Jing—she navigates different timelines and encounters classmates who become central to her journey. Among them are Han Yun, a studious but timid peer; Chu Yu, a warm-hearted senior; and twin brothers Cheng Hao xuan and Cheng Hao yu, whose contrasting personalities shape the group's dynamic. What begins as chance meetings between strangers evolves into genuine friendship as the characters support each other through the challenges of adolescence. Together they confront the complexities of high school life and reach the transformative threshold of turning seventeen.
