Thank you so much! I think their romantic relationship would deserve a whole new fic, but I'm not sure if I'll write one. Maybe it's best left open so everyone can make up their own mind on how Harry's and Severus' relationship goes on.
I imagine them finding their happy ending, even though I'm sure it will take a lot of hard work, lots of patience and possibly a couple of arguments (and, eventually, lots of hot sex :P).
