Shen Zhiyi, a primary school teacher in the county town, had a crush on Gu Huai, a repeat student of the director who transferred from the third year of high school - that cold young man who always drew scenes in sketchbooks and used an old SLR to take pictures of the campus. After graduation, the two broke off contact and learned that Gu Huai was admitted to the Beijing Film Academy. She kept her feelings deep in her heart and adhered to the "non-marriage principle", but was forced by her mother to go on a blind date because she was "physically unwell".
At the blind date table, she was shocked to see Gu Huai opposite her. She thought she was ordinary and she was embarrassed and wanted to run away, but Gu Huai called her by name and said with a smile, "You sat in the third row by the window in high school, and you liked to draw little suns in your homework books."
As they get along, Shen Zhiyi gradually loses her inferiority complex with the help of her best friend Lin Xiao, and discovers that Gu Huai remembers the hot milk she put in, that there is a secretly photographed profile of her in the sketchbook, and that her name is hidden at the end of the award-winning short film. His childhood sweetheart Lu Haoyu was rejected in his pursuit, and Gu Huai confessed that he was moved by her umbrella when he was caught in the rain when he was in high school. He went back to his hometown for a blind date because his grandfather was seriously ill, and the reunion was an unexpected joy.
The two went from contract marriage to true love. Shen Zhiyi published a collection of essays with Gu Huai's encouragement. Gu Huai made an award-winning documentary inspired by his hometown and her. Eventually, they had their daughter "Nian Nian", and Shen Zhiyi became confident and cheerful, living a happy life of "teaching the students he likes and accompanying the people he loves" in a small county town.
