Here are some Domestic Boyfriend/Girlfriend!Zutara headcanons because I’m trash
The two are literally the cuddliest couple you will ever meet. When most people who’d known Zuko before Katara see the two together, they’re shocked. Zuko has never seemed like someone who enjoys physical contact, but with Katara, it’s like they’re joined at the hip. If you turn around, they’re always holding hands, or linked at the arms, or hugging.
BUT they don’t throw it in your face. They aren’t one of those gross couples who can’t keep their hands to themselves. In fact, for the longest time, no one had ever actually seen them kiss. Besides cheek kisses, of course. Cheek kisses are a common occurrence. You’d think with all the motherly kisses Katara gave Aang, she’d give more than she receives. You’d be wrong. Cheek kisses are almost always given by Zuko to Katara.
One day though, Sokka caught them making out behind a pillar at the royal palace, and they were both so embarrassed they couldn’t look him in the eyes for a week. He has NEVER let them live it down.
Even as teenagers, the two were the mom and dad couple. Everyone KNEW they were going to get married. They act like grandparents. When Katara visits from the SWT, they take daily walks through the gardens and feed turtleducks.
Everyone in the Fire Nation hardcore ships the two. Ever since Katara saved Zuko’s life, the people have loved her. Zuko’s council didn’t like her at first, and hated the idea that a waterbender was invited to join meetings as an ambassador. Katara didn’t take any of their crap, and eventually won them over. When the two finally start dating, the Nation FLIPPED OUT. Towns and villages everywhere celebrated.
Once, at the start of their relationship, Katara confessed to Zuko that she always secretly loved the idea of running to hug someone and having them spin you in their arms. Ever since then, WITHOUT FAIL, Zuko makes sure to pick her up and spin her when they are reunited.
While Katara and Zuko have been jealous people in the past, the two are weirdly never jealous of the other… At least, not in the angry way most people are. When one sees the other talking to someone who may or may not be flirting, they don’t run over and start slapping them. The two just gravitate towards one another. So say if Katara is talking to a nobleman at a party and the nobleman starts sweet talking her, Zuko will magically appear behind her, wrap his arms around her, and join the conversation. If some Fire Nation fangirl starting giggling too much around their Fire Lord, Katara will be right next to them, giggling just slightly louder. The two are so in love with each other and oblivious to other advances, however, that they don’t realize that the other has come to rescue them from a flirty pursuer. They’re just happy that the other turned up.
They both have only had ONE angry jealous moment each, both at the start of their relationship. An adviser’s daughter somehow slipped on a piece of ice (which is so weird, since it was a FIRE NATION party) and into a servers tray of wine, and a poor, unsuspecting busboy who tended to flirt with anything and anyone stood too close to one of the torches in the room, and his pants burned clean off, leaving him in his underwear in front of everyone.
Zuko would never, ever, in a million years admit this, but he loves having his hair played with. Katara discovered this fact on accident. He was running late for a meeting and asked her to help him put his hair up. As she started to gather it up, she noticed he instinctually leaned in slightly at her touch. Curious, she continued running her fingers through it, and Agni as her witness, he closed his eyes and sighed happily.
Lucky for him, Katara loves playing with Zuko’s hair. It’s just so soft! During cuddles, she will always absentmindedly run her fingers through it and twirl it. Once it got to around his shoulders, she even started braiding it.
For all their cuteness, however, the couple has one fatal flaw: They’re competitive as fuck. It started with just Katara. Everyone was on a vacation at Ember Island, and the two were challenged to a beach volleyball game. They both got really into it, but Katara got too into it. When the opposing team won with a foul move, Katara lost it and started yelling at them. Zuko had to throw Katara over his shoulder and drag her away as she kept yelling. But then the opposing player insulted Katara, and Zuko flipped. The two went back for a rematch and obliterated them into the ground. They were sore winners, too.
Katara and Zuko are not allowed to play beach volleyball.
