Confidence. Smelling nice. A pleasant sounding voice. When it comes to the ladies, he has two types: the ones who can kick his ass and assert themselves and the ones who are domestic, maternal, and will fawn over him. I started to write a tl;dr about it years ago (and here it is if anyone cares.) He also has this weird way of having amazingly attractive girlfriends (I maintain it's because hot chicks are on some level unintimidated by a blind dude.)
