TUNG was mad. He grasped YEE with a knife and confronted with others. KONG deliberately slowed up and suggested MAN to approach him. TUNG got crazy suddenly. MAN and others caught TUNG and KWONG finally. KONG invited YING for dinner but was refused. They accompanied CHEONG to find his friend. On the way, they got lost with him. Luckily, it was only a false terror. The relation between YING and KONG had improved a great deal after that incident. YING suspected a karaoke bar had illegal connection with the police. KONG sent somebody by pretending as customers and discovered there were a lot of student girls and prostitutes. Every time they checked their licence, those girls always left quickly. KONG thought there might be someone notify them secretly. He sent MAN as an undercover who however stole the car of BROTHER B, the owner of the karaoke bar.
