Earlier...
Inside the adjacent room...
A man was tied to a post sitting on the chair facing the two-way mirror. His mouth was covered with duct tape and both his hands were tied securely by a rope behind his back. His legs were rope bound to the chair. He can't move his body but he can move his head. Tears were streaming down his face...while he hopelessly watched the lovers undress and make love right in front of him. Their erotic actions were so vivid and implanted in his mind forever. Tonight, he died of envy and jealousy over and over again.
