BUT introduces YIN to the people in Cheung Lai Yuen, requesting YUET to take care of her. BUT and DOU require YAN to finish the second half of the movement but the muse has left him. A drunk stops YIN’s sedan chair. SHAN exposes her identity as a girl when she is helping YIN out. She has become YIN’s trusted servant since the incident. YAN’s music has a western flavor. BUT therefore believes he used to live in the Western frontier. BUT takes YAN to the country. The scenery reminds the musician of how he and FUNG played together once in front of a waterfall. YIN requests to go out to practice when BUT and YUET are discussing about the command performance. Burning with curiosity, BUT follows her. Although she is well aware that he is peeping at her from a distance, she pretends to be ignorant about his presence to make him fall for her eventually.
