Angel No. 1 (Leon Lai) is very lazy, so he chose to be a killer who doesn't have to worry about the time, place, or who should die. Angel No. 2 (Michelle Reis) is very cold and beautiful, and is No. 1's superior. She likes to dress up and go out at night to clean the room for No. 1. Angel No. 3 (Takeshi Kaneshiro) is very strange. He never speaks. What he likes to do is to pry open other people's stores in the middle of the night to do business and take a camera to take pictures of his father. Angel No. 4 (Charlie Yeung) is very "realistic". Although she can't forget her ex-boyfriend, she can turn around and comfort herself in other ways. Angel No. 5 (Karen Mok) is very nervous and likes to show up on rainy nights. The five angels stubbornly and lonely move forward on their own life tracks. In order to avoid more sadness, they will remind themselves to "forget that he is him" when their tracks cross, but their true feelings will still be revealed involuntarily.
