The idea of stroking the heads of those who are "broken" is indeed an interesting one, but here's a question for you: if you find out that your parents died, no matter how stupid they were, you would just smile and go on with your life? And why would you suddenly be fascinated by a stranger you met two days ago at the most? Being attracted is acceptable, but we know that passion and love are different things.
Kutsuna with his life as a craftsman proved to be much more interesting than Ryou, but unfortunately he didn't have any kind of development, or even screen time except - for the most part - thoughts about the protagonist.
Art is indeed cool, but comedy is dull. It boils down to pissed off characters yelling at each other. About the mafia: it's an incredibly generic aspect in bl manga, and the way events were narrated was a little confusing. I also don't like the idea of polyamory, although this in particular is just my taste.
