Daughter Zhao Qing worked hard for three years and finally bought a car. She had promised in her childhood to drive and pick up her father Zhao Guoqiang, but she was always delayed by work, leaving behind indefinite "next times" over and over again. Zhao Guoqiang waited silently, outwardly understanding his daughter's busy life while living comfortably, but cherishing in his heart the warm memories of riding a motorcycle to pick up his daughter back then. Through an accidental opportunity, Zhao Qing understood her father's anticipation hidden in silence, put down her work, and drove home. The father and daughter retraced the old road all the way, looking back at their middle school days. Once upon a time, the father rode a motorcycle to guard her as she grew up; now Zhao Qing holds the steering wheel, fulfilling a promise delayed for many years. From now on, she will change to accompany her father and no longer let him wait alone.
