After the high school entrance examination, Xinyou, an asthmatic art student, and Jin Yan, a young man from a car repair shop, met for the first time because of paint stains. The grapefruit flowers and scars became hidden marks. When they reunited in high school, he silently paid attention to her breathing condition, and she secretly drew him repairing the car. Family pressure and repeated illnesses have become a wrinkle between the two - he hides his part-time job to raise money for his mother's medical expenses, and she gives up the opportunity to exhibit her art due to asthma.
Mint candies, rice water, and asthma spray became emotional bonds. From school uniforms to white shirts, from car repair shops to art studios, they planted pomelo flowers on each other's scars. In the end, her painting exhibition was framed by the mechanical device he designed. His car repair shop hung the pomelo flower sign she painted. The paint stains from the first encounter turned into a gentle smudge over the years.
Purpose: Healing and achieving each other
