I saw a book review and someone said that the prologue was a failure, so let me explain.

At the time of the prologue, the protagonist is only a few years old, a little kid, who can have the logic of wool, and when he encounters danger, his first subconscious reaction must be to run away, even if adults don't choose to rush up.

The first reaction is to come back to your senses before you think about it and find out what you should do.

No one is born brave, it is because of fear that they will be brave, and it is precisely because they know that they are weak that they will become strong.

That's what I'm trying to express.
