In order to protect the rare Ming and Qing books that need to be repaired, ancient book restorer Su Wan, and architect Lu Zeyan, in order to cope with the family's pressure to get married and overseas project authorization, arranged a two-year contract marriage through the help of their elders.
Under the same roof, he installed sensor lights in her restoration room and used drawing logic to clean up ink stains. She kept warm ginger tea for him and drew exclusive architectural sketches. From the "cohabitation agreement" of living in separate rooms, to the professional complementarity in the ancient town project; from the clumsy acting when grandma comes to visit, to the silence side by side when guarding ancient books on rainy nights, love quietly grows in the sweet scent of osmanthus cake and the ink marks on the drawings.
There is no bloody entanglement, only the long-lasting tenderness - when the contract expires, Lu Zeyan hands over a handwritten engagement: "This time we don't talk about the term, just talk about the rest of our lives." An ancient book, a blueprint, three meals for the two of them, and staying with each other throughout the four seasons, this is their most smoldering love.
