MR. KO has won a crystal stone, the history of which dates back to the Tang Dynasty. He is told that whoever sleeps with the stone for one night will find a happy marriage. He wants to keep the stone in a glass box. KWAI volunteers to find one for him. KWAI meets a boy on the street and takes him home out of sympathy. But she soon discovers that he is a little liar. She calls his father to tell him to come over. She cannot believe it that his father is KAU TSUN, a well-known wealthy bachelor in town. TSUN goes to Pakbaodot to invite KWAI to dinner. HOI-YEE is taking part in a charity performance, at which she will play a witch and sing to the piano accompaniment of BROTHER FROG. When she finishes, she kisses BROTHER FROG as requested by the MC and the audience. She is rather surprised to find BROTHER FROG in tears. MR. KO gives KWAI a mobile phone. It rings as soon as she has received it. It is TSUN who calls.
