Very heartbreaking and heartwarming that's the way I played it. Never easy to deal with the situation like this and think about how hard it would be for the person who became blind especially how this story starts.
Your wife, Emily, of two years recently went blind due to a brain tumour. The tumour also altered her personality quite a bit, sparking a great need for her husband's attention in the bedroom. [Edited to be a little slower, hopefully changing the tag from breeding to romantic won't change her personality too much]
