Overview: SUM uses the concept of intimate distance to explain MAN and SANG’s underground relationship. YIN does not agree with his conclusion. SUM has bought a gold peach for HAN on her birthday. SUM’s aunts have never liked HAN, so they are jealous when they see the gold peach. They even tease about HAN’s humble background when she is singing on the stage. SUM and TING interrogate SANG’s wife, MEI-YU. They are surprised when YU stresses that SANG and she are an affectionate couple. According to the result of HEI’s investigation, SANG has lost a lot of money in investment. He once lost two million dollars at one go, but he only earns fifty thousand dollars a month. What is even more unusual is that he is always able to recover his debt. YIN arrests SANG, who is trying to flee. SUM and YEE see a robbery. When SUM is describing the robbers’ features to the police officers in charge, MEI-SZ, an old friend of his, walks towards him.
