However medical checking shows that SUT had been poisoned to a comatose state before being killed in the traffic accident. Moreover there is no finger-print on the steering wheel. It is certain that it is a set up murder. YUNG and YI rush to save MAN but it is too late. MAN has been kidnapped by CHAI. Seeing that he has been surrounded, CHAI releases MAN and goes to the roof, trying to kill himself. CHAI committed the cases as he was shocked by his wife who had betrayed him. The situation worsened as he found that his son was not his flesh and blood. His anger explodes when he met the victims with “Envy”. His wife had a gift of “Envy” from her secret lover. He went insane and calmed himself by killing the victims. When he knew that he was suspected, he used tricks to frame SUT but in vain. He has to face trial by the law.
