KWONG expressed to FONG his love. FONG refuses him with the excuse that she has already got a boyfriend.......... KWONG is very upset. He intends to travel to Europe. FONG is eventually moved by KWONG who is so caring and sincere. KWONG sends FONG home. They meet KEUNG. KEUNG tells the TSUI's family the case. The TSUI's have different opinion on this case. KEUNG tells BON the news. BON pretends that he is all right. In fact, he feels very painful and upset. FONG remembers that BON has mentioned that a couple had asked BON the way during the night of the murder. FONG then posts BON's photo and writes 'Seeking young couple - good reward'. KWONG and TING show the poster at the main entrance of the concrete hall. They eventually find a female witness, FONG.
