This is the great chapter so far. I really like the development.
In this chapter they open and talk to each other. We know their character and interesting to see their opposite nature.
At the beginning I wasn't sure about his character, he is too brutal and though.
But if my prediction is true, my question has been answered here.
The boy is passive air-head. But there was something that made it that way, at first glance indicated earlier, he did seem to have a problem with the family line seeing his grandfather's reaction to him.
It is his true nature, he becomes bad, not caring, and from here the "psychological-love" arises. Someday, the girl will help him, change him. While at the same time, throughout the story, intrigue in the mafia.
