Conflict

 So, the conflict in the story...

I would say the problem in the story, is Gianni and his teen angst. 

He's always felt like he doesn't belong and so that causes him to act out and be impulsive. 

Now, that he found out about his biological father, it's sort of an excuse for him to act out. It's not that he has this desire to meet his real dad, he's doing this because he believes if he does, he'll finally understand who he is. 

Gianni needs to come to terms that he's growing up. During his travel, he realizes this. He also realizes that he doesn't need validation from adults to tell him who really is. Only he knows, who he really is.
