When September's phoenix leaves fell on the red wall of Mingde Middle School, Jia Yixin's stargazing diary reflected the shadow of another person for the first time.
She is a "distracted girl" who hides astronomy magazines from her mother and draws star maps in math class. He is a "mathematics geek" who carries planetarium tickets in his school uniform pocket and has pen cocoons wrapped around his fingertips. The adjacent names on the class schedule, the old telescope in the corner of the library, and the unspoken sentence "Orion rises on September 10th" make two originally parallel trajectories quietly intersect in the high-pressure high school life.
Ridicule and misunderstanding were like dark clouds passing over the star path, wrapped up in layers by their mother's ban, the teacher's prejudice, and class monitor Zhang Siqi's hostility. But when the Quadrantid meteor shower pierced the night sky, they finally discovered that the love that the world defines as "useless" is the starlight that illuminates each other.
A stargazing diary and an old telescope connect two teenagers' struggle and perseverance between test papers and star maps. It turns out that the most touching trajectory in youth is not the standard answers that follow the rules, but the moment when someone is with you on the rooftop at four in the morning, using the wrong question set as a stepping stone, and waiting for the meteor to pass by together - just like their meeting was written in the star path of the universe from the beginning.
