After his father's death, Li Kangsheng, who came to Tianqiao to set up a stall to sell watches, was like his mother. Although he did not feel much emotion with him, he could not get rid of his ubiquity in spirit. Because of a watch that shows the jet lag between Paris and Taipei, Xiaokang becomes acquainted with Xiangqi (Chen Xiangqi) who is going to Paris. From then on, he thought that he had made some kind of connection with Paris (Xiangqi) and got some kind of empty comfort. When Xiaokang expressed his ambiguous yearning for Xiangqi by turning the clock forward seven hours and watching the movie "four hundred strikes", Xiangqi, who was far away in Paris, did not find much positive meaning in life. No matter the same sex (Ye Tong) or the opposite sex, she can't get the warmth she wants from them.
