Mr. Chow and Mrs. Su form a bond when they both suspect their spouses of extramarital activities. They understand each other and the deep feeling of mutual love arises. But they don’t consider it is possible to imitate the example of their spouses, because they don’t want to lose the beauty and purity of their feelings. Chow and Su are like two musicians in a great orchestra; they play the melody of the mood of love being fully absorbed with it, while the entire orchestra is playing a quite different melody. Skillfully they interweave their melody with the full theme, without being able to stop, because this is the music of their hearts.
