I think his empathy is actually a great asset to work as a honey-trapper. He understands his partner's need too well, and provides them with the fantasy they want. He's the ultimate pleasurer.
In Enzo's case, there's been sexual attraction, but I guess there's more, because in season one, when Rian's kissing Enzo in his fantasy, we can't see his face and he looks more like Candy! I wonder if Enzo would notice their similarity once they meet~
I kinda agree. He hasn't been doing a great job, and in the end, instead of just seducing and extracting information, he's become obsessed too. But for feeling sympathy, as I mentioned, Enzo's resemblance to Candy might play a part, but there could be more. Rian said they're different, but there has to be a common factor in their backgrounds for the difference in their personalities to make sense. I guess Rian might not be unfamiliar with abuse, maybe a different kind, but the point is that he didn't end up cruel like Enzo.

But rian is too emotionally soft to be a honey pot spy…. I wonder if it’s just Lorenzo. I can’t believe evidence of physical abuse and a pretty face is all it took for him to feel this affected by a ruthless man who runs a mafia org from the shadows, who has threatened his life over and over not to mention has raped him. What is this lol.
