A House Full of You
Zuko had spent his whole life certain he would be the end of his line. That it would be kinder. Two winters into your arranged marriage, you draped yourself across his study cushions and asked him, very softly, for a child. His. Yours. A house full of them. He had not known, until that moment, how badly he had wanted to be asked. How long he had wanted to fill you with his name, his line, his everything. How starved he had been for the permission to want this out loud.
