The murderer in the play is called Lin Zhu, a high school student with a very delicate appearance and excellent grades, who is very popular.

Lin Zhu's parents have always been proud of him, and they would rather eat leftovers by themselves than Lin Zhu to eat well and dress well, so to speak, for Lin Zhu, they are willing to pay everything for him.

Several people stood together, and no one would have thought that Lin Zhu, who had an outstanding temperament and was polite and polite, was their son.

On the surface, this is a warm and poor home where parents love their children very much.

But the undercurrent behind the scenes, but no one has ever known.

No one knows that Lin Zhu, who has an excellent reputation for character and learning, is very disgusted with his parents in his heart, and often inadvertently and deliberately asks them for some expensive things.

These seem to be out of the vanity of an adolescent teenager, but in fact, Lin Zhu has always dressed extremely ordinary at school, and he never hides the fact that his family conditions are not good.

On this day, it rained heavily in the town.

After the rain cleared, someone found a body by the dock in the town, and the deceased was a female high school student.

The police immediately came to investigate, and in the end, the girl's death was defined as a misfall into the water and accidental death.

So the case was quickly closed.

But the girl's parents insisted that it could not be an accident, because their daughter fell into the water and almost drowned when she was a child, and since then she has a natural fear of rivers and seas, even during the day, she will not be near the water's edge, let alone walk on the beach.

If so, how could she have stumbled and fallen into the water near the water?

But the police were bent on closing the case, so they ignored the words of the girl's parents.

The girl's parents couldn't, so they had to be unwilling to find a relationship and wanted to continue to sue them.

Fortunately, the girl's mother, Shao Yang, a student she had taught before she got married, became a criminal policeman.

When he learned what had happened to his mentor when he was young, he immediately rushed over.

At this moment, a new dead person appeared in the town, and the other party was also drowned.

After some investigation, the police finally determined that it was an accident.

The keen intuition of the criminal police made Shao Yang realize that things were not simple, so he began to investigate.

But there has been no progress on the case.

Just when Shao Yang himself felt that it was indeed unexpected, another drowning person appeared.

Shao Yang, who rushed to the scene as soon as possible, was almost certain that this was not an accident.

What made Shao Yang's heart heavy was that the other party did not leave any clues.

It's simply the perfect crime.

But the more this is the case, the more unwilling Shao Yang becomes, and he tries every means to restore the truth.

Eventually, he set his sights on Lin Zhu, who looked like he was in a good mood.

After several attempts, Shaoyang was almost certain that several cases were related to Lin Zhu.

But he couldn't find any evidence!

It wasn't until another rainy day that Lin Zhu was finally caught red-handed by Shao Yang when he committed another crime.

And when Shao Yang grabbed Lin Zhu, Lin Zhu was like two people as usual, his eyes were gloomy and cold, like a demon.

When he arrived at the police station, he returned to his usual appearance, saying that he had no idea what he had done before.

This makes one wonder if he is a dual personality.

If that's the case...... It's not so easy to convict Lin Zhu.

But Shao Yang looked at him calmly and didn't think he was a dual personality.

Because even ordinary Lin Zhu is extremely lacking in empathy, and he doesn't have any mood swings in several cases.
