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]
It is a wide open scenario and it is a mixture for whatever mood you might be in or at least that is how i found it. Nicely done!
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.
