In the smoky "Nuanbao" bakery, the owner Lin Xiaoman is a baker who can make ordinary toast into a happy place. Her shop is famous for its wonderful combination of "healing desserts + ancient book knowledge" - every day, a heart-warming saying from ancient books is written on the blackboard along with dessert recommendations. One day, the aloof ancient book restorer Shen Yanqing accidentally walked into the bakery in search of an original copy of the Republic of China. However, his taste buds were pricked by the butter bagel with the pattern "bandit gentleman" printed on it that Lin Xiaoman handed him. Since then, Shen Yanqing has become a frequent visitor to the bakery. From the beginning, he only ordered a fixed type of bread, but later he would take the initiative to ask, "What dessert goes with the 'Shi Bu Ti Jing' on the blackboard today?" Lin Xiaoman broke Shen Yanqing's "cold barrier" with desserts, while Shen Yanqing took Lin Xiaoman into the world of ancient books. Together they restored the Republic of China manuscripts that contained love stories and sorted out old books in old bookstores. In the aroma of fermented dough and the ink fragrance of ancient books, they went from unfamiliar to familiar, and finally turned the daily life of "bread and ancient books" into the sweetest love.
