The well-known Japanese photographer Yashenqian (Xiangjing Li) was dragged to Paris, the romantic capital of France, by his sister Ai Sui (Tonggu Meiling). Who knows how soon after arriving, Qian was thrown by his sister alone on the banks of the Seine. In the midst of anxiety, Qian's passport was accidentally broken by a Japanese woman, who broke the heel of her high-heeled shoes. The other party, whose name is Kakei Kawahara (Miho Nakayama), is the editor of a local free Japanese newspaper. With the help of Kui, Qian found the embassy and the hotel where he stayed. At the same time, Ling Ai also meets his long-lost lover, Han (Ayano), a painter who works alone in Paris for his dream. After a short three-day trip to a foreign country, Qian and Kui get to know each other and like each other; after the joy of parting for a long time, Ling Love will also face many tests of long-distance love. Like the constant Eiffel Tower, silently watching the meeting and parting of the two men and women.
