Wah (Andy Lau) and Ngor (Maggie Cheung) were in love. In this scene, Ngor saw Wah leaving for Kowloon, she sensed that something was wrong, and Wah was indeed killed after. Ngor’s feeling was conveyed so completely just through the eyes of Maggie Cheung. She was deeply in love, angry, worry; she put on a sulky expression, yet she deeply cared for him. At this point, the audience knew she loved him without the why, in her mind, she could not articulate, yet fully realized that would not bring her any gains. A truly great work by Maggie Cheung.
