Katara was never good at dancing. It just wasn't her thing. So, of course, at the Firelord's ball celebrating his 18 birthday, she naturally just sat all by herself and watched. Since she was so bad at dancing and all.
And so, of course, because of the fact that she was so bad at dancing, Katara wouldn't dance with anyone. Even though some of the guys that asked her to dance were pretty darn cute. So, yeah. Katara was just sitting there, enjoying her…well; actually Katara wasn't enjoying herself all that much. But she could pretend.
And then, the shadow of this guy fell on her. And, of course, she looked up. And saw the firelord. She couldn't possibly refuse, since it would probably start another war or at least some sort of political crisis. And Katara was the ambassador to the Water Tribe. So she pretty much didn't have a choice. Besides to dance with Zuko.
And what do you know, for some strange reason when Katara was on the dance floor with Zuko, she was actually an okay dancer. For someone who'd never had a dance lesson in her entire life. Zuko wasn't all that bad himself, though. And he was pretty handsome, for a Firebender.
So that was why she said yes. When Zuko asked her to marry him. And when Katara was walking up that aisle, she decided that it was pretty lucky she was an okay dancer. Because otherwise, she might not be marrying Zuko. But maybe it wouldn't have mattered to him if she wasn't a good dancer. Maybe.
And when Zuko came into the room, looking as cute as ever, Katara decided he definitely would have married her anyway. Because he loved her, and love doesn't care about dancing.
What is it they say? She wondered, staring into Zuko's amber eyes. Then, when her lips met his…Ah yes, I remember. Opposites attract.
