Remus, Remus, Remus. :) I identify with him much more than with Sirius, who is brash, impulsive and charismatic where I am quiet and perhaps not as brave as I should be. I'm attracted to Remus's calm composure, his kindness and how good a teacher he is, and I enjoy seeing him through Sirius's eyes/POV. I'm instinctively more protective of Remus just because I love him as a character so much, though god knows Sirius has been through enough crap of his own.

No preference for who's pining or who makes the first move. :)
