“Wo Yao Ni De Ai” by Grace Chang is heard early in the film, setting the tone as a throwback to Classic Hollywood romantic comedies.

“Wo Yao Ni De Ai” was a hit song by Chinese actress and pop star Grace Chang from the 1950s. Based on the Louis Jordan jump blues song "I Want You to Be My Baby," “Wo Yao Ni De Ai” was part of a new wave of Shanghai-based pop music called shi dai qu, or “songs of the times.” Shanghai has always been a city where Eastern and Western cultural influences met. This came together in a unique genre of Shanghainese fusion pop songs called shi dai qu during the 1930s-1960s that spread all across Asia.
