In the fast-paced modern society, Su Xiaotang, the cultural blogger of "Paper Years", has gained millions of fans by sharing unpopular knowledge in ancient books and interpreting interesting things about ancient people's lives. However, he was criticized by netizens for being "archaeologically graded" because he misjudged the version of ancient books during a live broadcast. And this complainer is none other than Lu Jingchen, the master of ancient book restoration who lives in seclusion in the old library. An accidental ancient book restoration experience event brought the two people together offline. Su Xiaotang originally wanted to "please bear apology", but while working with Lu Jingchen to repair the moth-eaten Qing Dynasty "Jade Poems", restore the handwritten notes from the Republic of China, and explore the hidden stories behind ancient books, he was gradually moved by his craftsmanship and gentle details; Lu Jingchen was also infected by Su Xiaotang's love for culture and optimistic and cheerful personality, and changed from the initial "cold god" to the "exclusive feeder". While unlocking the secrets of ancient book restoration and inheriting traditional culture, the two staged a sweet love story in a time filled with the fragrance of ink. They also inspired more young people to fall in love with ancient books and pay attention to cultural inheritance, becoming the "most educated couple" in the mouth of netizens.
