Oh so interesting. I need to examine whether the same might not also be true for me (find one character in an OTP that I admire and love). I know I have been unable to really ship certain characters because I find them unrelatable, but what I tend to relate to is the messy stuff. But I have never been drawn to an all-out villain, so there is no doubt a degree of admiration for the character(s) that I need to have.

I also wonder if I also have a physical type as well. I know I am more drawn to Sherlock physically and I really like reading fic where his slenderness and hair are explicitly emphasized.
