Plot: KAI-CHUNG points out that the way his parents treated KAI-KEI is outrageous, and he does not believe that TO SUM and his daughter killed KAI-CHO; whereas TUN-YU thinks KAI-CHUNG to be disobedient, intending to hit him. When YUK-KAM sends some food to KAI-KEI, who has no appetite, she tells KAI-KEI to look after herself because TO YUNG is so unreliable that she can only rely on KAI-KEI to rescue TO SUM
