Honestly mafia stories with good endings to me are just corny and unrealistic. I’d rather read a mafia story with an ending that makes you want to throw yourself across the globe. For example,
He/She ran away with their fellow gang members because their gang was exposed. He/She tried to follow them but ended up losing them. In the end they found someone who loves them and they found nothing and continued to lead the gang.
Or like here’s this quote for example,
I’ve heard rumours all over town about them. I choose to stop listening, wherever they are and whatever they’re doing, I wish them the best.
Seeing character development in the gang member or mafia leader is unrealistic. Once you’re a mafia you can’t get out. BUT
Seeing the person who you choose to be in love with the gang member or mafia leader, it’s eh somewhat realistic when they have character growth, because they learn from mistakes.
