I adore their storyline and they have a great dynamic (fucked up, but this is GOT there are no normal ships) after SanSan I definitely love this Sansa ship most. He seems to genuinely care about her and she could really give him the motherly affection he didn't have and he could teach her a lot about the world in a kinder way then Sandor could. I'm not super into smut of them but I like them being very close friends or having a more innocent romance.
