If we talk about romance, being in love with mafia doesn’t make sense for me, because mafia members are the least guy I will find hot. I hate to disgust them in real life. So I think it’s just for a kink lol. And if it’s for that reason, then it’s not suitable for episode platform which is for 13+
But as a story I like mafia story with a good plot based on research. A story that “smart” and not involving innocent girl or toxic relationship.
Too bad though, I don’t find many of stories like that here.
Since most of the time are always I and others mentioned above, I will skip mafia story in general if it pop up in my recommendation.
