Lin Zhiyu, a natural-study girl, entered the city's No. 3 Middle School with her talent in science and calligraphy skills. The three years of junior high school were filled with the ignorant heartbeat in the chirping of cicadas, the fierce competition on the scholarship list, and the pull of two completely different emotions - she chased the handsome figure of Jiang Yichen, hid her secret love in the wrong question book and the shouts in the basketball game, the touch of her fingertips when borrowing a pen, and the love of sharing an umbrella. Rainy nights have become the most precious fragments of youth; but Shen Yan, the elegant young man wearing gold-framed glasses and standing on the rostrum to calmly preside, hides his paranoia in his eyes, protects his shortcomings with double standards, is always sticky, and writes his protection that no one knows with the glances he makes during the broadcast.
