Lin Qingzhi, an ordinary girl who is as ordinary as a green zhi fruit, and her childhood sweetheart Jiang Linchuan, who has the aura of "god of learning", entered the highly competitive Zhenhua High School together. Qing Zhi, who looked up to him like looking at the stars in the distance, buried her sour secret love deep in her heart, tried hard to follow him into the astronomical club, and clumsily approached his world. During the three years of high school, it was Qing Zhi's silent watch beside Ti Hai and the astronomical telescope, and it was Linchuan's unknown pressure and confusion under the halo. Together, they experienced the fierce battles of academic studies, the throbbing of youth, the test of friendship, and the pull of family expectations and grew up together.
The college entrance examination sent both of them to the same top university. University is no longer a simple competition of scores. Major differences, future plans, a broader world and better people bring new challenges and opportunities to the relationship between the two. Can Qingzhi's secret love be cleared up? Under the dazzling light of Linchuan, is there also a unique dependence on the "Qing Zhi" around us? From Zhenhua's desk to the starry sky of the university, from an ignorant boy to a responsible young man, a long-distance race of pure love spanning the entire youth, on the star track of chasing dreams, writes the ultimate answer about courage, companionship and two-way running.
