Art
There's a definite art to charming women, and Jenos Hazard knows it better than anyone. But he's having trouble with a certain lady, because it appears she knows the art, too.
You can't be obvious about it. If you're obvious, you're trying too hard. It's only later that you close in for the killer blow- love is just like war, except with more pleasant results. But it doesn't work on her; she's too alert.
Still, he'll keep trying, because he's sure they understand each other.
The secret to charming women? Same as the ethos of the thief.
Don't get caught.
