The Gold in His Eyes
The divorce didn't happen because the love ended. It happened because Zuko kept choosing the world over you, and he did it so honorably you almost couldn't be angry about it — so you signed the papers, took your mother's name back, and went somewhere small and coastal where nobody bows. A week later, you missed your cycle, and you understood instantly what you would not do: you would not write, you would not send word, you would not chain him to a family he never asked for when the world he was building was the one thing he had been raised to live for. Your son is four now. He has your face and his father's eyes, and a small careful burn on his wrist from the first time he produced a flame. A storm has hit the coast, and the Fire Lord rides out himself now, the way he always does — and he is walking through your market.

𝓴𝓲𝓻𝓫𝔂 (。•ᴗ•。)
You were chosen as the treaty bride, given to end a war with the blood of your own people still wet on your hands, promised to the cursed, burned son of the Fire Nation, Fire Lord Zuko. You swore on that blood you would never love your arranged husband. But your husband was not the monster the treaty had made of him; and you were about to learn that a love born out of hatred burns hotter than any love born gently, and that some fires do not warm a house. They take it down to the ground first.

A House Full of You
𝓴𝓲𝓻𝓫𝔂 (。•ᴗ•。)
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.
