Based on the happy collaboration of the previous movie " Love is in the Air ", director Besançon invited singer Sinclair to work on the production of the original soundtrack. "When I made the first film, I was very happy with Sinclair, so I'm definitely looking for him this time." Sinclair is one of the few people who saw the script for the first time, and Besançon started discussing with him very early. During filming, Sinclair often visited the scene to capture the atmosphere of the film. In order to ensure that the music and the video are in harmony, I must also do it myself when editing. The director is very satisfied with the cooperation with Sinclair.
In addition to music tailored for the movie, the director also chose many old songs from the 1970s and 1980s as movie episodes. Regarding the selection of these songs, Besançon said: “In general, try to find music that is an annotation to the scene that is happening. For example, Janis Joplin's version of "Summertime", I think it is the type of Marie-Janna, she must I like it. Sometimes, what moves is the contradiction between the lyrics and the scene. For example, "In pursuit of happiness" in the hospital scene after a car accident and Lou Reed's ghostly "Perfect Day" at the end of the film. The scene is enriched by these music."
