Sansa/Littlefinger. Though I'm not sure it's entirely accurate to say I abandoned it, because I was never fully in it. I read the books and went hmmmm... Then found the fandom and one particular writer (I'm sure she isn't the only one) who was so fucking sanctimonious about how AWFUL the books' treatment of female characters was, while at the same time she was writing pedofic. The hypocrisy just made me roll my eyes and leave.
