Chen Shugen, an 80-year-old retired teacher, met Lin Xiaohui, a 25-year-old roasted gluten stall owner, during a square dance. The age gap and secular prejudice cannot stop the two hearts from getting closer. From the tacit understanding of each other during morning exercises to the accompaniment of fireworks in the night market, they use ordinary daily life to fight against the passage of time. Faced with opposition from their children, comments from neighbors and hidden dangers to their own health, the two used the gluten-baked stall as a bond to weave a true love that spans age groups in the trivial details of life. The story uses delicate writing to show the tenderness in reality and interprets the tenacious growth of love under the shackles of the secular world.
