Zhang, a wealthy businessman, had a mistress in the suburbs with whom he maintained a luxurious house, treating her like a canary in a gilded cage. His busy schedule allowed him to meet with her only once a week. However, Zhang had a strict rule: he forbade her from having affairs or cheating on him. To ensure this, he discreetly installed a camera in the room to monitor her private life.
One day, after a long day at work, Zhang decided to check what his mistress was doing via the camera feed. To his surprise, he saw an empty room, with only his mistress inside, applying makeup. He found it strange for her to be doing this so late at night and felt a pang of suspicion.
After a long while, she finally finished her makeup. Just then, someone knocked on her door, and she quickly went to answer it. Zhang's heart sank, as it was evident that another man had come to meet her. He was about to confront her, but his eyes widened when he saw the other man—it was himself.
Suddenly, Zhang's heart stopped, and he fell to the floor, a knife protruding from his chest, blood gushing. He watched in horror as the scene unfolded on the screen. The next day, he was left completely bewildered.
The following night, Zhang went to a nightclub with some business friends. Encouraged by his friends, he took two ecstasy pills. After the club closed, he felt as light as a feather, so he drove to the suburbs to meet his mistress. He parked the car, rushed inside due to the rain, and knocked on her door. She opened it with a playful smile and said, "Feeling cold? Let me make you a bowl of ginger soup."
