When a top student transfer with a tendency to cry at the slightest thing stumbles upon the aloof heartthrob’s secret cat-feeding routine, a decade-long bond begins, written in mathematical formulas and answered through design sketches. From high school classrooms to international fashion weeks, from sharing an umbrella in a rainstorm to risking their lives for each other amid the ruins, Lin Xiaoxing and Jiang Yuchen express the most profound romance in the clumsiest way: You are the one exception to all my reason.
