How does "Love Killing by Phone" plan an unsolved case?

In the next crime scene, the audience is even less likely to agree with the heroine, because she just appeared when the car seller tried to kill her, so you can't sympathize with someone you don't know at all, so you can't agree with her position. Then, after choosing to identify with the hero, the audience hopes to commit a crime and kill the heroine. The audience hopes to get a pleasure of killing by killing the heroine.

This concept of criminal identity has been maintained until the end, that is to say, the audience has always hoped that criminal acts can be implemented and criminals can succeed. However, at this moment, the psychological position of the audience has changed because of the appearance of the positive image of the police. When the audience finally met this image, they remembered the moral principles they should stick to, so they returned to justice in the process of police solving crimes.

While the police solve the case by reason, the audience hopes that the police can succeed and bring the criminals to justice. At this time, the audience's psychological position shifted from the criminal to the heroine and the police, holding their breath and waiting to solve the case, hoping that the police's intelligence could be comparable to that of this criminal elite with superior thinking. Sure enough, the police took advantage of the criminals' mistakes in the car dealer's keys and finally succeeded in solving this vicious wife-killing problem, but the audience gained a sense of justice in punishing the murderer in the process.
