They were walking down the beach of ember island, hand in hand, in a comfortable silence. Zuko suddenly stopped and pulled Katara to his chest and kissed her forehead, with a small smile on his face. Katara wrapped her arms around Zuko's waist and kissed the spot right above his heart. She then rested her head on his chest and she listened to his heartbeat, the constant and steady thumping relaxing her better than anything else in the world ever could.
"I wish we could stay like this forever," Katara said with a sigh.
"Nothing would make me happier," Zuko held Katara close to him and kissed the top of her head. He took a deep breath and chuckled to himself.
"What's so funny," Katara said, pulling away and looking Zuko in the eye.
"It's just," Zuko tucked a piece of Katara's hair that had fallen out of place behind her ear and smiled lightly, "five years ago I was trying to kill you and your friends, I was so lost, and didn't realize how horrible of a person I was, or how terrible the choices I made were. But you've helped me find myself, and now we're engaged and going to be married in three months." Zuko placed his hand on Katara's stomach, which had an almost unnoticeable bump and smiled. "And we're expecting a baby! So much has changed. I don't know what I did to deserve this."
"So much has changed" Katara said, putting her hand over Zuko's. "And it's changed for the better. And you deserve happiness just like every other human being. Just because you've made mistakes doesn't make you a monster. Everybody makes mistake. It's the fact that you learned from them and grew as a person that makes me love you so much."
"You're amazing" Zuko kissed his fiancée lightly. Katara wrapped her arms around his neck and smiled.
"I love you so much," he said.
"I love you, too," she said, "Everything is perfect."
Oh how wrong she was.
