Deep in Autumn Alley, ancient book restorer Su Qingyuan is guarding the old bookstore left by her grandfather, struggling to survive in business difficulties; ancient building restoration designer Chen Yu meets her because of a renovation project. The two had no intention of falling in love, but they gradually developed a tacit understanding due to working together. They jointly solved the practical problems of ancient building restoration and bookstore self-rescue. They treated each other with frankness and supported each other, and worked together to build an old bookstore into a new space where ancient book restoration and ancient building culture are integrated. Pages of paper reflect bricks and tiles, ingenuity meets a close friend, and in the day and night in the old alley, they live together as the warmest daily life.
