It was not teenager A but teenager B who really killed Moriguchi's daughter. The original idea of teenager A was just to make an electric shock device that could directly kill Moriguchi's daughter, so as to gain the attention of others.

But the stun gun made by teenager A didn't kill Moriguchi's daughter, so he was very angry and made fun of teenager B, who threw Moriguchi's daughter into the swimming pool, which directly led to the death of the little girl-but he didn't destroy the evidence to hide his eyes and ears, but he felt that teenager A couldn't kill Moriguchi's daughter, but he could.

Teacher Moriguchi calmly told the story in the last class and began to prepare for revenge.

The first step of her revenge was to cheat two children, saying that she mixed the blood of AIDS patients with milk and let teenager A and teenager B drink it.

Then Mr. Moriguchi left and said goodbye to the class.

The new teacher in this class is Victor, who happens to be the husband of Moriguchi, a follower of Sakuramiya Justice. He believes in Sakuramiya's view of "influencing children with love".

Moriguchi used this to guide Victor to visit teenager B every week. At that time, teenager B had been tortured by AIDS and guilt and lost his mind. Under the constant visit of teacher Witt, teenager B became more and more crazy and even killed his mother.

But teenager A found that he didn't actually have AIDS, and he didn't even care about himself. As long as you get your mother's attention, it doesn't matter whether you are infected with AIDS, commit suicide or even kill someone.

A teenager who is indifferent to life decided to make a big news at the graduation ceremony-he installed a bomb under the podium of the graduation ceremony to attract his mother's attention, even if it was only once.

Unexpectedly, at the graduation ceremony, the bomb did not explode as scheduled. It turned out that Mr. Moriguchi had the bomb. Moriguchi knows the character of teenager A and that death is not the biggest revenge of this student. Moriguchi even told teenager A that the bomb had been transferred to teenager A's mother's office-that is, just now, teenager A pressed the button of remote control bomb explosion.

Juvenile A knelt down and finally got what he deserved.

Moriguchi also smiled and said with tears at the moment: I'm kidding.

Confession is not only about the protagonist's revenge, but also about the juvenile law that protects juvenile delinquency. Keigo Higashino, a famous Japanese detective novelist, also criticized the juvenile law in his novel The Wandering Blade. Compared with the Wandering Blade, the thinking about this law in Confession is darker and deeper.
