"Youth is not only an ignorant heartbeat, but also becoming a better self through the influence of each other."
Under the shade of the sycamore trees at Qinghai Middle School, Bai Ning, a "novice" in mathematics, and Shen Lin, a cool top student who has always been at the top of his grade, unexpectedly became roommates. One is a vigorous girl who is top-notch in liberal arts but always gets red-eyed in front of math problems, and the other is an aloof young man who is indifferent and alienated from the people around him and only focuses on solving problems.
When Bai Ning chased Shen Lin to ask for advice on trigonometric functions, when Shen Lin silently shielded her from the dazzling sunlight during morning reading, those problem-solving notes hidden in the corners of the draft paper; the two people's fingertips intertwined in panic in the library; and the umbrella they held together on rainy days; all became the most tender look of youth.
Intention: Two-way growth and mutual achievement
