Lau visits Susan in hospital and mentally confesses the truth to her. She reveals that she already knows he tried to murder her because she was still partially conscious when he drugged her and locked her in the kitchen. She then asks him if he ever really loved her. Lau realises that, in his desire for revenge, he has destroyed a new family he created with Susan. Susan does not believe him, loses her will to live, and dies. Yau meets Lau outside the hospital and tells him his conclusion. Lau returns to Susan's room, where he feels overwhelmed by guilt and eventually commits suicide by shooting himself in the head.
