I write a comment about HUGO.
In Hugo, there are three characters.
Desma is a girl whose hair is black and she wears glasses.
Celestine is a girl whose hair is blond.
A moth man is incarnation of a moth. i assume that he is "Hugo".
The story is as follows:
Desma and Celestine belong to a science club. They compete to win the science prize.
Desma and Celestine are friends. But, they are the rival each other.
One day, Desma tries to kill a moth. But, she set it free accidentally. Then, she try to capture it again. But, she meet a moth man. At first, she try to kill him. But, gradually, she is attracted to him. She comes to love him.
In the contest, she is going to show people Hugo to win the prize.
But,she can't show him, because she loves him. She release him. He flies away somewhere.
In my opinion, the author tells us the importance of life and insists that we must not kill creatures for the selfish reason.
